The output relay is a 4 pole, double throw; it has four independent switch contact
sets, where the pole (common) connection on each set switches between NO (nor-
mally open) and NC (normally closed) contacts. Note that the relays may be con-
figured to be energized or de-energized on receipt of an alarm event.
l Active Condition De-energized requires an alarm event to release the relay.
l Active Condition Energized requires an alarm event to energize the relay.
