The Helmet Communication System from MSA is a

state-of-the-art radio interface device which significantly improves the user’s ability to receive and send messages even in loud ambient-noise environments. It goes wherever you go. The system consists of a helmetmounted microphone and ear speaker assembly that weighs 5.3 ounces and easily snaps onto the user’s fire helmet or industrial-style helmet’s ratchet suspension.

need to lift your lapel mic up to your ear to hear

transmission.

• Easily snaps onto the ratchet suspension of fire

helmets or industrial-style helmets. The unit can be

easily transferred to other users, and no tools are

required for removal.

• Can be used over the top of facepiece head

harnesses, hoods and liners without losing the

quality of the transmission.

• The bone-conduction microphone is made of soft

silicone material, which makes it comfortable to

wear, with no pressure points.

• The helmet microphone assembly can be reversed

on the helmet suspension to position the ear

speaker on either ear.

• The helmet mic system, when used with the lapel

mic or PTT, is powered by the battery from the radio.

No need to replace or re-charge dry cells.

• Special connectors suitable for most common radios

are available for the lapel microphone and PTT,

which allows users to adapt the system to their

existing radios.

• The helmet mic is NFPA-certified which allows its

use while fighting fires.

• Intrinsic safety approvals allow the use of the

Helmet Communication System in hazardous

environments.

• The stand-alone 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 which

allows for storage of the cable when it’s not

connected to the lapel mic or PTT.
