Solution 2000/3000 - Hardwired Fire/Smoke Detector

By default, Output 2 on Solution 2000/3000 is designed for Fire/Smoke Detector.

The Event Code for Output 2 is 2,7 Fire Alarm Verification

Connect this output to the negative side of any Fire/Smoke Detector. To configure an output for this feature, use these settings:

EVENT Code – 2,7

POLARITY – 10

TIMEBASE – 2

MULTIPLIER – 15

This feature is used on some commercial fire control panels to reduce false alarms from smoke detectors. It is similar to zone pulse count used in some motion detectors.

A fire zone is allotted a pulse count of 3 pulses over a period of 3 min.

If the smoke detector trips, the voltage to the smoke detector is disconnected for 15 sec and then reapplied. No alarm is registered. If the unit activates again within 3 min of the first activation, no alarm is registered and the voltage to the smoke detector is again disconnected for 15 sec and then reapplied. If a third activation is detected within 3 min of the first activation, (three pulses in 3 min) a fire alarm is registered.

Power to the smoke detector is maintained to facilitate unit identification through the detector memory.

The zone to which the Fire or Smoke detector is connected should be programmed as:

ZONE TYPE – 13

ZONE PULSE COUNT – 3

ZONE PULSE COUNT TIME – 15
