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 con-

dition.

Serial/Parallel Printer Module, and the SK-5280 Status Display Module. All circuits are 24 VDC regulated.

3.14.1 Setting ID Codes

Before installing the SK-5235, SK-5217, 5824 or SK-5280, you must first set their identification codes. Each

device must be given its own identification code. For example: each SK-5235 needs a unique ID code, but a SK-

5235 can have the same ID code as a

SK-5217. Each type of device has it’s own device type programmed into it enabling the control panel to

distinguish between the different devices.

On the back of each device is a small 4-position dip switch used to set the ID code. Use the chart below to

Relay contacts are rated at
