Honeywell Alarm Control Card

Alarm Control Cards monitors through reversal of their polarity, are mainly utilized to control actuators. The card is suitable for use in systems that include devices conforming to the NFPA standards, where it can activate the alarm sounders.

Overview

Honeywell Alarm Control Card periodically performs the test on the single channels by inverting the output signal for a duration of about 200 microseconds. In case of discrepancy between the configured signal and read signal, the station signals a fault situation. For each single output, the following situations are checked: Line opening, Short-circuit towards positive, Short-circuit towards negative, pilot DMOS device fault, pilot DMOS device overheating, Supply voltage out of admitted limits. All the channels are tested during operation every 2 seconds.
