Emergency - Motorola APX 7500 Detailed Service Manual

Feature Operation: Emergency

The Consolette supports a logic input that when asserted can trigger an over-the-air Emergency
Alarm as if the user pressed the Emergency button on the front of the O5 control head. This interface
can be used with an Emergency Footswitch. The user would have to modify the accessory to attach
to the DB25 accessories connector on the rear of the Consolette. To activate this input, the
EMERGENCY* signal must be pulled to a logic low (less than 0.8VDC).
NOTE: A "normally open" switch which grounds when activated is required for this interface.
