Configurable for intercom only
The headset can be configured for intercom-only use, which makes a crew position part of the conversation without putting it on any radio channel.
The reason to buy it
Built & serviced in Lemoyne, PA — by firefighters, since 2009
500-Series wireless
UHW503.V2crew headset
The crew seat's headset: DECT7 under-helmet wireless with 24dB protection, configurable for intercom-only use so the position hears everything and keys nothing.
Why a crew-specific model+
The 503 has no radio transmit and no stereo listen-through, and it can be configured for intercom-only use. That is a deliberate control, not a stripped-down headset: crew positions hear the intercom and the radio without being able to key a channel, which is what keeps traffic clean on a working incident.
Where it sits in the line+
It lists at $945 — the same as the 505 — so this is not a budget decision. You choose the 503 because that seat should not transmit. Black is the standard colour on all 503.V2 headsets, where red is standard on 507 and 505 models, so the crew headsets are identifiable on the rack.

Product overview
The UHW503.V2 is the headset for the seats behind the officer. It is a DECT7 under-helmet wireless headset on the same platform as the rest of the 500-Series — 24dB noise reduction, 24 hours of talk time, auto-on within six seconds of coming off the charging cable — and it is deliberately missing two things.
It does not transmit on the radio, and it does not carry stereo listen-through. It can also be configured for intercom-only use. Those omissions are the product. A crew of six with radio transmit on every headset is a crew that can step on the officer, on dispatch, and on each other; a crew wearing 503s hears everything and keys nothing. Deciding that at spec time is far easier than fixing it after the apparatus is in service.
It still direct-wires to a portable radio, which matters once a firefighter leaves the apparatus and the wireless base station behind. That is the path back onto dispatch, and it is deliberate rather than automatic.
One practical detail: black is standard on all 503.V2 headsets, where red is standard on the 507 and 505 models. The crew headsets are identifiable on the charging rack without anyone reading a label.
For the seats that do need to transmit, see the 505 models or the 507 Bluetooth models. The wireless side needs a WB505R.V2 base station.
What this model does
Hears everything, keys nothing
The 503 is defined as much by what it will not do as by what it will. Both halves are below.
No radio transmit
Unlike the 505 and 507 models, the 503 does not transmit on a connected radio. On a six-person crew that is the difference between clean traffic and six people able to key over the officer.
Direct-wire portable radio
The headset still wires straight to a portable two-way radio with a FIRECOM portable radio adapter cable, which is how a firefighter stays on dispatch once they are away from the apparatus.
24dB noise reduction
All 500-Series wireless headsets carry a 24dB noise reduction rating. Sirens, an unmuffled exhaust, and a pump at working pressure stop being the reason a message gets missed.
All 500-Series
Auto-on and 24-hour talk time
Lift a headset off the charging cable and it powers up and connects within six seconds. A full charge carries 24 hours of talk time, which covers a long incident without a battery swap.
All 500-Series
Black as standard
Black is standard on all 503.V2 headsets where red is standard on the 507 and 505. Crew headsets are identifiable on the rack without anyone reading a model number.
Silicone ruggedizers in fourteen colours are available across the line if you want to go further and colour-code positions or apparatus.

FrequentlyAsked Questions
Before you request a quote
Because it is not a cheaper headset — it is a different role. Both list at $945. The 503 is the same DECT7 platform with the same 24dB protection and the same battery; what it gives up is radio transmit and stereo listen-through, and those omissions are why you would choose it for a crew seat.
Usually every seat behind the officer and driver. On an engine with a driver, an officer, and four crew positions, that is commonly two 505 or 507 headsets and four 503s. Send us the riding positions and we will lay out the mix.
Yes, by direct-wiring to a portable two-way radio with a FIRECOM portable radio adapter cable. That is deliberate: the firefighter has to connect to a radio to be on it, rather than being able to key a channel from the intercom position.
It restricts the headset to the crew intercom. FIRECOM headsets are set up with the Configuration Utility, so features can be enabled or disabled and then standardized across a fleet rather than configured one headset at a time.
Black is standard on all 503.V2 headsets where red is standard on the 507 and 505, so they are already distinguishable. If you want to go further, silicone ruggedizers come in fourteen colours and are commonly used to colour-code positions or apparatus.
