The UM belt-mounted interface features a very capable VOX switch, usable in ambient noise to 120dBA and a large PTT (Push to Talk) jam-proof button. The SED exclusive PTT button allows the User to actuate the radio transmit even if the User is wearing bulky gloves. The PTT button is available in two styles: recessed, or raised.
Like the HALO® belt-mounted VOX/PTT, the SRI interface is a big button PTT only to allow the user to operate their radio more easily in adverse condition or while wearing protective gear. Simply attach the unit between the HALO headset and radio and in place in the UM.
The HALO™ SRI is intrinsically safe. It requires no power and is transparent to the radio and attached headset.
