Advanced Bluetooth wireless technology allows the connection of 4 BT-COM communication units, providing uninterrupted intercom connection between up to 4 operators.

Ease of Use

The Protos® BT-COM capsule connects into the existing Protos® ear defender bracket. No wiring, drilling or clamps are required to fit to your Protos® helmet. All of the BT-COM technical components are incorporated in the ear defender capsule and with no cables and connectors, this guarantees maximum comfort with no risks of snagging. With only a single multifunction button and two volume buttons, the BT-COM can be easily operated with just one finger.

With a range of up to 300 metres (clear site) and a battery operating time of up to 12 hours, the Protos® BT-COM will go through one working day without problems. Recharging the battery is easily done via the USB on the Protos® charging bracket. A full charge takes around 1.5 hours and the BT-COM can remain in standby for several days.

4 User Bluetooth Communication System and Phone Compatibility

The BT-COM allows the connection of 4 BT-COM units providing uninterrupted intercom connection between four operators. There is also the ability for each unit to be connected simultaneously with a mobile phone via Bluetooth. Accepting phone calls can be done hands-free by pressing the multifunction button with no need to remove the phone from a pocket. Once an outgoing phone call is executed from the hand-held device, the conversation can be carried out hands-free via the BT-COM. The conference function allows another participant to be added and the distance can be extended as long as a mobile network is available.

The Protos® electret microphone diminishes unnecessary background noises by up to 20 dB whilst always guaranteeing clearly understandable voices. Background noises remain perceptible, allowing any external danger situations to be recognised.

Bluetooth allows interference-free communication in areas where there are strong radio frequencies and Bluetooth connection does not incur any licence charges.
