Push-to-talk radio transmit
The 51 designation means this headset can key a connected radio. It is the configuration for the officer, the driver, and a pump position — the seats that own radio traffic.

51-Serieswired headsets
The wired headsets for seats that key the radio: push-to-talk radio transmit, hands-free intercom, 24dB protection, and no battery to charge.
Reading the model numbers+
UH is under-helmet, FH is overhead. The 51 designation means the headset transmits on the radio with push-to-talk and runs hands-free intercom. An S suffix is a situational-awareness variant: UH-51S has one slotted ear dome, FH-51S is a single-ear configuration.
Who gets a 51+
Seats that must transmit — typically the officer, the driver, and a pump position. Seats that should hear the radio but never key it belong on a 52 or a 54 instead. That is a deliberate control on channel discipline, not a cost saving; the prices are within $5 of each other.

Product overview
Wired headsets are still the right answer for a lot of the fleet. There is no battery to charge, no pairing to lose, and nothing to power on — the headset works because it is plugged in. FIRECOM's 50-Series is that line, and hundreds of thousands of emergency responders are on it.
The 51 models are the ones that transmit. Push-to-talk radio transmit plus hands-free intercom is the configuration for a seat that owns radio traffic: the officer, the driver, a pump operator. All four carry a 24dB noise reduction rating, which is the number that matters when sirens and an unmuffled exhaust are what you are talking over.
Wear style and situational awareness are the two remaining choices. UH-51 and UH-51S mount under a helmet; FH-51 and FH-51S are overhead. The S variants trade some of the seal for awareness — UH-51S has one slotted ear dome, FH-51S is single-ear — which suits firefighters who need more of the scene than a full seal allows.
For seats that should hear the radio without keying it, see the 52-Series and 54-Series headsets. These connect through a 5000-Series digital intercom or a 110 or 210 radio interface. Wear items are on the FIRECOM parts and accessories page.
What these models do
The rugged performance you depend on
One garbled message on a call is one too many. The 51-Series is the configuration for the seats that have to be heard on the radio.
Hands-free intercom
Crew intercom without pressing anything, so a conversation inside the cab works the way a conversation does. The 52 and 54 models handle the intercom differently on purpose.
24dB noise reduction
Sirens and unmuffled exhaust are no match for FIRECOM's 24dB noise reduction rating on wired hearing protection headsets. The rating is identical across the 50-Series, so the model choice is never a hearing-protection compromise.
All 50-Series
Overhead or under-helmet
FH-51 and FH-51S are overhead. UH-51 and UH-51S mount under a helmet. Wear style and radio role are independent decisions on this line.
Situational-awareness variants
UH-51S adds a slotted ear dome and FH-51S is a single-ear configuration, for firefighters who need more of the surrounding scene than a full seal gives them.
UH-51S, FH-51S
Serviceable wear items
Ear seals in PVC and ComLeather, acoustic foam, cloth covers, mic muffs, hygiene kits, hanger hooks, and the HE-150 glove-rugged coil cord extension are all replaceable parts rather than reasons to buy a new headset.

FrequentlyAsked Questions
Before you request a quote
Seats that have to transmit — usually the officer, the driver, and a pump position. Everyone else should hear the radio without being able to key it, which is what the 52 and 54 models are for. The prices are within $5 of each other, so this is about channel discipline rather than budget.
They trade some of the seal for awareness. UH-51S has one slotted ear dome; FH-51S is a single-ear configuration. Both are for firefighters who need to hear more of the scene directly. They cost the same as the standard versions.
Wired headsets have no battery to charge, nothing to pair, and nothing to power on. Wireless lets a firefighter leave the seat and stay on the intercom. Most departments end up with both — wired at fixed positions, wireless where people move. For the wireless side, see the 505 wireless headsets.
A FIRECOM intercom. On a full apparatus that is a 5000-Series digital intercom, usually through an HM-10 headset module or an HM-30 pump panel module. On a smaller vehicle it is a 110 or 210 radio interface. Tell us what is in the rig and we will confirm the connection.
