Monitoring and Testing
Refer to the characteristics of the detectors connected to the interface.
Lid-open protection is triggered when the rear inside cover of the device is opened: in order to obtain forced removal protection in the two installation solutions you must install a longer spring (included) on the tamper switch, so that it stays pressed down against the bottom of the 503 housing and/or wall.
The devices are alarm “concentrators” for any type of intrusion detector and can be connected to:
a) 2 NC/PULSE (4080):
- by selecting NC they control one or more normally closed magnetic contacts installed in series, with a 500msec opening alarm;
- by selecting PULSE each one controls a hard-wired window blinds detector operating on a NC/NO switching counter (alarm after 6 switches).
b) 4 inputs (4080) or 6 inputs (4081) for active/passive detectors that manage alarm and tamper functions on a balanced line.
The six types of alarm are managed individually by the control panel, according to programming.
