monitoring of alarm devices via inverted voltage (24V) and fuse of 1-4 outputs; Four individually controllable voltage outputs and/or sum control and/or evacuation function (priority input). Constant or pulsating signal on output. Display and button allow system calibration. Indications for which output and what it is alerting for (interruption or short circuit).
By default, the card comes with four F2A fuses that can be secured up to 2 A per output (maximum 8 A total for the entire card). Possible to monitor star networks about 5 loops per output. Monitoring is done with 10k resistance per loop. Possible to set positive (24 V at alarm) or negative (0 V at alarm) logic. Alarm output for securing and/or loop failures. On Display:
- The number of loops connected.
- the number of activated cargo exits (via alarm control);
- Alarm for: loop failure, short circuit and impedance failure.
Mounting: Wall
