Product Information
Improves the user’s 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 user’s lapel mic or PTT.
A custom user-positioned ear speaker brings all incoming communication directly to the user’s 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 user’s 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.
