NGA-705 i s a fully monitored interface module, which is used to connect a number of current limited conventional detectors to the Addressable control panel via the detection loop. These detectors are then seen as one address at the addressable control panel. Three LEDs are provided to indicate module status.

The module is powered exclusively from the Loop. The detector line is monitored by a bipolar electrolitic capacitor. This will reduce considerably the quiescent current load on the loop. The Green LED will pulse every time the unit is polled by the panel. The Yellow LED will be ON whenever there is a fault condition in the module and finally the Red LED will be ON when there is an alarm condition in the conventional zone.
