Table 3-4: Table showing the default settings for relays
Note: Relays 3 and 6 are permanently configured for Urgent Fault and Fire 1 (any sector) respectively. All
other relays can be re-configured. Multiple functions can be attached to a relay provided the
combined voltage does not exceed 5 VDC.
3.4.3 First alarm sector relays
The first alarm sector relays are Factory set at Default to relays 8, 9, 10 and 11. Refer to Table 3-3 on page 16
for further information. These relays are activated once the sector assigned to the relay has an event where
the alert alarm is first activated. Once the first alarm sector relay has been activated on one sector, the first
alarm sector relays for other sectors will not be activated unless the system is reset.
