3.13 Auxiliary Relays
The SK-5208 provides four programmable auxiliary relay outputs. Relays can be programmed
to activate for the following conditions, either for all zones or by individual zone: pre-alarm
(not acceptable for NFPA 72 Central Station), fire alarm, auxiliary alarm, alarm by zone, and
system or circuit troubles (loss of AC, low battery, failed to communicate, phone line troubles,
fire drills, and notification circuit troubles).
Refer to the SK-5208 programming manual for more information. Figure 3-10 shows the relay
contact connections using a door holder application as an example.
Note: Relays programmed as “Trouble” will be active during normal state and deactivated during a trouble
condition.
