  • Type 2.

    Same as above except the master units microphone, is switched audio from the Sirenco siren system Model SC3D control head. This saves having two microphones in the cab. The same microphone can be used for Public Address through the siren system or switched via a button to the intercom system (LED gives indication of function i.e. P.A. or intercom).

    Type 3.

    Same as type 1 and type 2 with the additional advantage of the slave units being able to access the vehicle 2 way radio. The slaves can be used as either the intercom, or by activating a local switch at the crew cab or pump, communication over the 2 way radio can occur. This enables the Brigade personnel to maintain pump operations and communicate via 2 way radio if required. Or, if trapped at a fire and taking refuge in the crew cab area, personnel can make a distress call without having to gain access to the cabin of the vehicle.

    The main 2 way radio microphone in the vehicle cabin has priority over the slave units in accessing the 2 way.
