Product Information
Improves the users ability to receive and send messages by
incorporating a "noise-reducing" bone-conduction voice transmitter
that virtually eliminates high ambient noise levels. Made of soft
silicone, the microphone is comfortable to wear with no pressure
points and can be reversed on the helmet suspension to position the
ear speaker over either ear.
The portable system consists of a helmet-mounted microphone and ear
speaker assembly that weighs 5.3 ounces. The helmet mic/ear speaker
assembly connects to a lapel microphone or optional basic PTT
(push-to-talk) unit and is permanently fitted with a connector for
attachment to the radio of choice.
When used with the lapel mic or PTT, the system is powered by the
battery from the radio with no need to replace or re-charge dry cells.
Special connectors suitable for most radios are available, which allow
users to adapt the system to their existing radiosA plug-in truck
communication adapter can be used by firefighters, along with their
helmet microphone assembly, allowing the user uninterrupted
communication from the time the alarm sounds until the incident is
over.
At the scene, the truck system cable is unplugged from the helmet
microphone, and the helmet microphone cable end is connected to the
users lapel mic or PTT.
A custom user-positioned ear speaker brings all incoming communication
directly to the users ear, without the need to lift up your lapel mic.
Easily snaps onto the ratchet suspension of fire helmets or
industrial-style helmets (Wildland) and can be transferred to other
users helmets without the use of tools. This device can be used over
the top of facepiece head harnesses, hoods and liners without losing
the quality of the transmission.
Intrinsic safety certifications allow the use of the Clear Command HCS
in hazardous environments. The basic PTT unit is designed for use
under hazardous material suits. The large button makes it easy for the
user to depress and communicate. The helmet mic incorporates a cable
keeper providing cable storage when not connected to the lapel mic or
PTT. An optional remote finger PTT is available as an accessory.
