This is determined by how many people will be riding in the vehicle on a regular basis. Typically, one headset is installed for each seating position. Wireless headsets typically eliminate the need for job- or location-specific headsets, such as at the pump panel, or at the turntable and ladder tip on an aerial, because they have the range to work anywhere.

Under-helmet headsets have a soft strap that goes over the head, allowing the headset to be worn under a fire helmet or inside the cab. Overhead-style headsets have a rigid headband and are used without a helmet. 50-Series Wired Headsets are plugged in to a headset jack to connect with the intercom. A 50-Series Wired Headset with single or a slotted-dome allows the user to hear ambient noise, such as traffic or voices on the foreground. 500-Series Wireless Headsets with Listen-Through Technology provide the same function with full hearing protection.

Firecom 500-Series Wireless Headsets have Stereo Listen-Through Technology, which allows you to mix in outside sound so you can monitor equipment, hear warnings or talk with someone not wearing a headset, all without removing your hearing protection or losing contact with your crew.

When worn properly, Firecom Headsets are built to handle rugged working conditions like rain, snow, mud and dust.

Yes, a cell phone can be used with a Firecom FHW507, UHW507 Wireless Headset or the DW501BT Direct-Wire Headset using Bluetooth™. Watch this video for pairing instruction, or consult the User Manual.

Yes. Firecom offers interface cables (sold separately) which allow you to connect a portable radio to a 50- or 500-Series Headset. Firecom supports virtually all radios. Check out our Radio Interface Guide for a complete list.

With a Firecom system, transmit capability is determined by the headset, not the position. A transmit headset can be in any position. Intercom-only headsets will not transmit on the radio at any position. Wireless headsets can be positioned anywhere if they have radio-transmit capability through a properly configured base station.

Yes. Wireless headsets can be used at the tip of an aerial or in the bucket, and they offer continuous communication during transition up and down the ladder. Check with Firecom for optimal base station positioning in this application. Our exterior module for wired headsets can be installed at the tip of an aerial or in the bucket of a ladder tower.

Firecom systems can connect up to 10 wired and up to 5 wireless headsets per wireless base station. Contact service@firecom.com (888-561-8098) for more information.

Yes. For wired headsets, simply install an additional interior or exterior headset module and run the cable; no additional intercom boxes are required (up to 10 available connections).

Yes. Firecom offers solutions for one or two people. These systems work well in water tenders, brush engines, ambulances, and command vehicles.

Yes, we can design a system to accommodate the unique requirements of an ambulance, whether you have just one radio or a combination of radios and cell phones. Here’s a sample configuration.

Yes, Firecom systems can be configured to allow multiple radios to transmit at the same time.

The Firecom 5000D Series takes apparatus intercom systems to the next level by offering automatic squelch, enhanced noise reduction circuitry, touch pad adjustable volume utilizing membrane switching, and bright LED indicators. The enhanced noise reduction is achieved by utilizing automatically controlled, dynamic range-expanding preamplifiers at each headset, which control the audio input for the intercom and radio. Expanding preamplifiers reduce excess noise from unused microphones, resulting in better clarity in noisy environments.

The intercom allows for simultaneous radio-transmit and intercom communications without the concern of intercom conversation being transmitted over the air.

Yes, up to four (4) radios can be connected to a 5000D Series Digital Intercom (capacity based on model selected). Ex. 5100D allows 1 radio, 5200D allows 2, etc.

Yes, a cell phone can be used with a Firecom intercom system if it has hands-free capability (provided your phone has a headset port/aux jack). Direct-wired cell phone conversations will be broadcast on the intercom to all crew members.

Firecom intercom systems do not include cabling. We do recommend you order a bulk roll of communication cable that we offer. Using modular plugs, cables can be run as required and trimmed to the proper length.

Accessories like replacement batteries, FH-Series Headbands, ear seals, mic muffs, ear dome ruggedizers, NFPA compliant hanger hooks, and more are available for purchase. Visit our accessories page.

The Environmental Protection Agency requires any hearing protector sold in the U.S. to have a noise reduction rating (NRR). NRR is a measure of a hearing protection device’s ability to reduce the wearer’s sound exposure. The higher the number, the greater the potential for noise reduction.

NFPA 1500 recommends hearing protection for firefighters while riding in or working around fire apparatus with a noise level in excess of 90dB (approximately the noise level of a hair dryer or lawn mower).

Firecom’s 500-Series Wireless and 50-Series Wired (dual ear dome) Headsets reduce ambient noise by 24dB when worn properly, which meets NFPA, OSHA, and Cal/OSHA standards.

Firecom Headsets connect to each other through a Wireless Base Station using DECT7® Wireless Technology. The base station connects directly to a 5000D Series Digital Intercom, which brings together the Wireless Headset users and the apparatus’ two-way radio.

Firecom 500-Series Wireless Headsets enable natural conversation in the apparatus; no yelling required. DECT7® Wireless Technology offers more audio bandwidth, which means the headsets sound great. We combined our industry-leading audio quality with our exclusive auto-leveling, noise cancelling microphone so that you can understand the subtle differences in what you hear even while the sirens are blaring.

Watch this video on basic headset features.

Microphones on the forward edge of each ear dome can be turned on to allow the user to hear environmental sound. Use Firecom Listen-Through Technology when you need to remain aware of scene noise, monitor equipment or speak to someone outside your crew without the need to remove your headset and its vital hearing protection.

The maximum sound level that Firecom Listen-Through Technology will let you hear is 95 decibels. If a sound should exceed that (a gunshot or explosion, for example), the headset will instantly shut down the ear dome speakers, protecting you from the sudden noise. You’ll hear a few moments of silence, followed by a gradual return to your previous settings.

Watch this quick video on Firecom Listen-Through Technology or follow the instructions below.

Toggle the Listen-Through feature on and off by pressing the FWD (►) and BACK (◄) arrow buttons on the right ear dome at the same time.

To adjust the Listen-Through volume, press the FWD (►) and BACK (◄) arrow buttons on the right ear dome. Listen-Through volume cycles from OFF to MAXIMUM. There are a total of five volume settings.

Note: Listen-Through volume controls are independent of crew audio volume. Mix in as much or as little as you need to stay safe and remain aware of your surroundings.

When the Listen-Through feature is active, you may toggle between the OFF volume position and the last selected Listen-Through volume setting by briefly holding down the FWD (►) and BACK (◄) arrow buttons respectively.

Yes. Firecom offers interface cables (sold separately) which allow you to connect to a portable radio to a 50- or 500-Series Headset. Firecom supports virtually all radios. Check out our Radio Interface Guide for a complete list.

Regardless of where you are or what you are doing on the apparatus, the radio-transmit button is always where you can find it, right next to your ear on the headset. There is no need to search for a remote push-to-talk switch or climb back in the cab to talk on the radio.

No. Firecom DECT7 Wireless Technology operates in a different frequency spectrum than two-way radios, so there is no interference.

Yes. Radio transmit is permanently disabled on Firecom’s UHW503 Intercom-Only Headset. Visit www.firecom.com/products/wireless-headsets/uhw503/ for more information.

Yes, a cell phone can be used with a Firecom FHW507, UHW507 Wireless Headset or the DW501BT Direct-Wire Headset using Bluetooth™. Watch this video for pairing instruction, or consult the User Manual.

You can pair a Bluetooth wireless device to any of our Bluetooth compatible headsets (DW501BT, FHW507 and UHW507). Here’s a quick video on how to do this.

Watch this video or follow the instructions below.

To create a new Bluetooth pairing:

1. Turn off the headset, and then turn it back on.
2. The headset will enter Bluetooth pairing mode for 10 minutes after power on.
3. From your device’s Bluetooth connectivity options, search for new devices.
4. Once the search is complete, select “HS-####-Sonetics.” If prompted for a password, enter four zeros (0000).

To answer or hang up a call, quickly press and release the Menu (▣) button on the left ear dome.

Watch this quick video on how to pair a headset to a base station, or review the full instructions in the User Manual.

For our complete illustrated fitment guide, refer to the User Manual. Here are a few key steps to remember when putting on your headset:

1. Inspect the ear seals (the pads that rest against your head) for damage before use.
2. While wearing, make sure that the ear seals rest against your skull without sitting on any part of your ear.
   • Tip: some ear jewelry & glasses can interfere with a good fit
3. The microphone should be no more than 1/8″ from your mouth.
4. Adjust the headband or soft strap for a comfortable, gentle fit across the crown of your head.
5. It is normal to feel a bit of pressure when you wear the headset properly. The seal protects you from dangerous noise levels.

Under-helmet style (UHW) headsets have an adjustable cloth band with hook-and-loop closure to adjust for different head sizes. Over-the-head FH-Series Headsets have an adjustable rigid headband.

The headset will respond to many button presses, menu selections and other status changes with voice prompts and/or tones. For example, when you turn on the headset you’ll hear “Firecom on. Battery high. Base Station connected.”

A sticker on the inside of the right ear dome displays your headset’s model and serial number. To see it, remove the ear seal and inner foam cover from the right ear dome (the one without the microphone boom).

Firecom 500-Series Wireless Headsets have a Noise Reduction Rating (NRR) of 24 decibels, which meets NFPA, OSHA, and Cal/OSHA standards.

When worn properly, Firecom Headsets are built to handle rugged working conditions like rain, snow, mud and dust.

Traditional voice-activated (VOX) microphones require manual “squelch” adjustment to function properly. If the squelch is adjusted too low, the microphone will be activated by almost any sound; if it is adjusted too high, it will only pick up very loud or forceful sound. Improper squelch adjustment can be frustrating, as the system will not function as intended. Firecom’s exclusive automatic squelch optimally adjusts microphone sensitivity, eliminating the need for manual adjustment. This allows for much better radio and in-cab communications.

This can depend on headset style and programming. A Firecom Wireless Headset can be programmed to require push-to-talk, or hands free VOX activation. Firecom Wired Headsets are pre-programmed so that some of the headsets require PTT at all times, and some allow hands free VOX activated intercom communication.

You will receive up to 24 hours of talk time after charging the headset for up to 4 hours.

A status LED on the left ear dome will flash from 1 to 4 times when the headset is powered on. Four flashes indicate a full charge. A single flash means it’s time to recharge the headset. When your headset is first powered on, you will hear a prompt indicating battery level, “Firecom On. Battery High / Medium / Low.”

Use the installed charging cable at your seating position or use the provided 12VDC regulated wall adapter. For details on Portable Wireless System charging, refer to the User Manual.

Accessories like replacement batteries, FH-Series Headbands, ear seals, mic muffs, ear dome ruggedizers, NFPA compliant hanger hooks, and more are available for purchase. Visit our accessories page.

Firecom’s Wired (dual ear dome) Headsets reduce ambient noise by 24 decibels (24dB NRR), which meets NFPA, OSHA, and Cal/OSHA standards.

The most common intercom-only headset requires the user to push a button to talk. We do offer one wired headset with a toggle on-off switch that opens the microphone for continuous intercom communications. Neither headset will transmit on the radio.

Traditional voice-activated (VOX) microphones require manual “squelch” adjustment to function properly. If the squelch is adjusted too low, the microphone will be activated by almost any sound; if it is adjusted too high, it will only pick up very loud or forceful sound. Improper squelch adjustment can be frustrating, as the system will not function as intended. Firecom’s exclusive automatic squelch optimally adjusts microphone sensitivity, eliminating the need for manual adjustment. This allows for much better radio and in-cab communications.

You’re ready to work!

Both the wireless headsets and the ComHub use custom Lithium-Ion batteries that charge inside each device using the provided 12VDC wall adapters or by using the charging cables inside a Firecom Charging Case.

The remote head is a duplicate of the intercom faceplate that can be located anywhere inside the vehicle. All controls, such as volume and radio selector, on the intercom box are duplicated on the remote head. The remote head is typically mounted flush on the radio console or in the OEM overhead console, reducing dashboard clutter. An optional adjustable mounting bracket is available for mounting the remote head on top of the dashboard or on the ceiling. Outside the apparatus it is often positioned on or near the pump panel.

The main intercom box can be mounted anywhere inside the vehicle, such as behind the officer’s seat in a custom cab, behind the bench seat in a commercial cab, or in the vertical cabinet of an ambulance.

The remote head is connected to the main intercom box with a six-conductor phone cable. This is the same type of cable used to connect the wired headset modules and wireless bases to the intercom box.

The 5000D Series Digital Intercoms come with 1 jack for a single remote head. By adding a splitter you can have provisions for two or more remote heads.

Accessories like replacement batteries, FH-Series Headbands, ear seals, mic muffs, ear dome ruggedizers, NFPA compliant hanger hooks, and more are available for purchase. Visit our accessories page.

All Firecom Intercoms have the same 9-pin connector (see manuals for pin out). On all MR cables, short the male pins 3-4 on DB-9 to see if the radio will key.

• If the radio will not key, check the programming.
• If the radio keys by shorting pins 3-4 on the DB-9, the problem is between the headsets and the intercom.
• Check the back of the intercom’s female DB-9 connector, pins 3-4, using an ohm meter during push-to-talk. If the relay is closing, the value will be less than 5 ohms.
• Check all RJ connector ports on the back of the intercoms. See if the pins are up or have been bent down all the way. This is usually from improperly crimped RJ connectors (see “Crimping RJ connectors”).
• If the pins are bent down, replace the RJ connector on the cable that was plugged into that port and use a pick to pull up the pins. If the pins will not pull up, the intercom will need servicing.

1. Press and briefly hold the power button on the right ear dome.
2. The status LED on the left ear dome should begin flashing.
3. If the Status LED does not flash, connect the headset to the power adapter and allow it to charge. Allow the headset battery to charge for a minimum of 4 hours to allow for up to 24 hours of operational use.

If the headset will not turn on after performing Steps 1–3, contact Service.

1. Is the ComHub or base station powered on? Check the ComHub’s status LED (to the right of the POWER button). It should be flashing green. If not, press the POWER button.

   Note: If you’re using a stand-alone Wireless Base Station, connect it to your power source using the supplied 12VDC adapter. The Base Station’s power LED will show a steady green.

2. Is the headset powered on? Check the headset’s status LED on the left ear dome. If there is no light, press and briefly hold the POWER button on the right ear dome. The status LED should begin flashing red, and you’ll hear a voice prompt announce “Firecom on.”
3. Is the headset paired to its base station? As the headset turns on, a voice prompt will announce “Firecom on. Battery (high/medium/low).” If you turned on your ComHub prior, the headset will announce “Base Station registering,” followed by “Base Station connected” when pairing is complete. If you don’t hear that prompt, check the headset’s status LED. It will flash green if it’s paired to your ComHub or Base Station. If it’s flashing red, it’s powered on but not paired. Follow the procedure in Pairing Headsets to Base Stations.
4. Check the volume level. If your crew members can hear you but you cannot hear them or yourself, adjust your headset’s volume level using the PLUS (+) and MINUS (–) buttons on the left ear dome.
5. Check the microphone sensitivity setting. If you hear your voice cutting in and out, or your crew reports hearing outside noise when you speak, make sure the distance of the mic boom from your mouth is within 1/8 inch for optimal results. Adjusting the microphone’s sensitivity may also eliminate the problem. Refer to the wireless headset manual under the “Advanced Menu – Mic Sensitivity” section for available settings.
6. Check the radio/intercom transmit setting. If neither you nor your crew can hear your voice, check the headset’s radio/intercom transmit setting. The default mode is Radio VOX with hands-free intercom and push-to-talk for radio transmit. Return the headset to its default transmit mode by following the procedures in the User Manual to access the Advanced Menu and adjust the radio/intercom transmit setting.

1. Ensure the headset you are attempting to pair is one designed to pair to a wireless base station (UHW/FHW503/505/507).
2. Ensure the headset powers on properly and has a sufficient battery charge.
3. The headset may require a firmware upgrade. Please contact Service for assistance with firmware upgrades.
4. After the firmware upgrade has successfully completed, attempt again to turn on the wireless headset and pair it to the wireless base station.

If the pairing is successful, the problem is resolved.

If the problem continues, contact Service.

• Charge all Firecom Wireless Headsets overnight before pairing and programming.

A sticker on the inside of the right ear dome displays your headset’s model and serial number. To see it, remove the ear seal and inner foam cover from the right ear dome (the one without the microphone boom).

If there is a problem with the intercom (and not an installation issue), we recommend returning the equipment to Firecom for repair. Our customer service staff will assist you with repair or replacement of your intercom and components. Visit Service for more information.

Firecom intercoms and headsets come with a 2 year warranty, which is unmatched in the intercom industry. Firecom will honor the warranty on our products regardless of who performed the installation.

Watch the installation overview video.

1. Crimp the RJ connectors on the Firecom six-conductor intercom cable. Firecom intercom cable has a smooth side and a flat side with a rib. The lock tap on the RJ connectors must be on the same side of the cable at both ends, ether smooth or flat. When the RJ connectors are crimped on correctly, the white wire is on the right side on one end, and the left side on the other. If the RJ connectors are reversed, the headsets and bases will not be able to communicate with each other or over the intercom or radio. Additional intercom cable can be ordered by calling Firecom at 1-800-527-0555 (Part no. 108-0102-00).
2. Route the cable. Avoid routing the cable with the coax from the radios. This may cause RF bleed over into the intercom resulting in a sizzling, hissing, or squealing sound in the headsets. If there is no other path to route the cable, make sure the coax is double-shielded as this will reduce the interference.
3. Mount the HM-10 headset modules. For best all-around performance from your HM-10s, the module may be placed with the plug facing the direction of the exit from the vehicle.
4. Mount the PP-20 modules. Mount the PP-20 in a vertical position. To prevent water build-up, drill a 3/32″ weep hole at the lowest point in the housing.
5. Power the intercoms. Use a single-point ground for the intercom and the radios. This will ensure the quietest operation possible. Use a power connection that will supply a minimum of 11.5VDC with proper fuse. Use a Firecom power filter to help eliminate power spikes and dropouts that may result from starting the vehicle or running the siren and equipment.
6. Mount the intercoms. Mount Firecom intercoms in an area that will not expose them to water or moisture. If this is not possible, use a plastic or fiberglass Water-resistant enclosure.
7. Mount the optional remote head. The remote heads are rated for interior or exterior mounting. Place it in an easily accessible location, so you can reach it when needed.
8. Install the wireless bases. Mount the bases on glass to ensure maximum range and usability. If glass is not available, plastic or fiberglass will work, provided no metal is directly behind the bases. Wire the power switched or hot through the fuse to the bases. Keep bases away from water and moisture by mounting inside a vehicle, or in a plastic or fiberglass enclosure if used on the exterior.
9. Install the wireless headsets. Wire the power hot all the time through the fuse to the headsets. For fastest charge, keep the power switch off while headset is charging. Use a hanger hook and secure the charge cable with a loop to avoid pulling on the headset.
10. Install the wired headsets. Clean the headset plugs with IPA or rubbing alcohol prior to use. This will help reduce static caused by dirt, grease, or deposits during shipping and handling.
11. Using wireless headsets. Disconnect the charge cable before using the headset. Program the microphone gain on each wireless headset. Keep the microphone about 1/8″ from your mouth for optimal performance for most applications.
12. Charging wireless headsets. Use only the 12-volt charger adaptor or vehicle power to charge your Firecom wireless headsets. Anything else may damage your headset. Charge the headsets overnight before programming and pairing them. This will allow quick and easy programming and pairing. Also check to see if the headset battery is charged; indicated by the red or green light blinking.
13. Adjust the intercoms after installing the equipment. Adjust the TX audio, and RX audio after installing the radio. This will set the proper audio levels for transmitting and receiving over the radio and intercom. Verify the setting by performing radio checks without service equipment. See intercom manuals for adjustments or visit Service.
14. Adjust squelch depending on your system type. You will need to set the squelch to on for wired headset system, and off for a wireless headset system.

This is up to you, as it depends on your skill level and comfort. Our systems can be installed easily with simple hand tools and the Firecom crimp tool. Most installations utilize a pre-made interface cable; however some radios, typically older models, must be hard-wired to the intercom, which will likely require the services of a radio technician. To ensure peak performance, final audio level adjustments will also require the skills of a trained radio technician.

Yes, we work with all the major apparatus builders. In fact, most builders prefer our products to other intercom systems because of the ease of installation and serviceability.
