(Refer to Drawing #4146, 3 of 3, for Relay Layout)
K1 - Discrete warning relay for channel 1
K2 - Discrete warning relay for channel 2
K3 - Discrete warning relay for channel 3
K4 - Discrete warning relay for channel 4
K5 - Discrete warning relay for channel 5
K6 - Discrete warning relay for channel 6
K7 - Discrete warning relay for channel 7
K8 - Discrete warning relay for channel 8
K9 - Discrete warning relay for channel 9
K10 - Discrete warning relay for channel 10
K11 - Time delay relay for horns (warning & critical)
K12 - Warning relay for strobes and RTU
K13 - Critical relay for RTU
K14 - Fault relay for strobes and RTU
Warning Level Alarm
1. For warning alarm, the normally energized relays in the control module will change state and apply
coil voltage to non-energized alarm relays.
2. The warning relay for connection to a RTU will energize.
3. The relay controlling the blue strobe for the sensor in warning alarm will energize.
4. The relay controlling the common blue strobes will energize.
5. The time delay relay controlling the horns will energize for a number of minutes determined by the set-
ting of the relay.
6. The time delay relay can be acknowledged through a push button switch located on the front door of
the system.
Critical Level Alarm
1. For critical alarm, the normally energized relays in the control module will change state and apply
coil voltage to non-energized alarm relays.
2. The critical relay for connection to a RTU will energize.
3. The time delay relay controlling the horns will energize for a number of minutes determined by the set-
ting of the relay.
4. The time delay relay can be acknowledged through a push button switch located on the front door of
the system.
5. The time delay relay will energize even if it had been acknowledged on the warning alarm. In order for
this acknowledge to happen, each control module must have its appropriate configuration switch in the
correct position.
Fault Alarm
1. For fault alarm, the normally energized relays in the control module are wired in series so that when
any controller goes into fault, or upon loss of power, the relay controlling the white strobes and the RTU
will become de-energized.
