MIS-09 Vehicle Intercom System with Emergency Vehicle Siren system
The MIS-09 was designed for the armored vehicle industry to allow the driver to communicate
with a person outside, without opening a window. As well as an intercom, the MIS-09 also includes two sirens. The main siren is a full function 100 watt siren which meets North American Emergency Vehicle standards. The Auxiliary siren provides Wail and Yelp functions at a lower volume for closer proximity use.
The system consists of a main intercom unit and a siren amplifier which are mounted under the dash board, a paging horn and siren speaker mounted under the hood and a small microphone which is mounted in the outside rear view mirror on the driver’s side. It includes a hand held microphone with push to talk switch which hangs on a clip mounted on the dash.
Once installed and connected to the vehicle’s 12 volt electrical system, it is ready to use.
To operate the system, simply turn on the power switch. A green LED illuminates to indicate
that it is functioning. Adjust the left hand volume control (Outside Mic) to obtain the desired volume from the outside microphone. You will hear this through a speaker built into the main unit.
In order to speak to people outside the vehicle, press the talk switch on the hand held microphone and adjust the second volume control (Inside Mic) to the desired level. When you press the talk switch, the internal speaker is muted, so you won’t hear your voice coming back through the outside microphone.
There are three switches to operate the sirens. For the auxiliary siren, turn on the siren switch on the right side of the unit. The main siren is controlled by two front panel switches which select Yelp, Wail or Manual mode.
