2-2 SW1 - RELAYS AND ALARM
2-2.1 SW1, Position 1: Summary Relay Supervised / Unsupervised
Configures the Summary Alarm relay as supervised or unsupervised. If a relay is supervised, the relay
picks until power goes off or until an alarm is detected. The alarm then releases to announce a change in
state. An unsupervised relay picks only when an alarm is detected.
1 = Supervised
0 = Unsupervised (factory default)
2-2.2 SW1, Position 2: Relays Latched / Unlatched
Configures all relays as latched or unlatched. If a relay is latched, the relay will remain in an alarm
condition until the Reset switch is pressed. If a relay is unlatched, the relay will remain in alarm until
either the Reset switch is pressed, or the condition that tripped the relay goes away.
1 = Latched
0 = Unlatched (factory default)
2-2.3 SW1, Position 3: Zone Relay Linkage
Configures all Zone Alarm Relays to link together and pick simultaneously upon alarm. When this switch
is turned on, if a zone goes into alarm, all six zone alarm relays and the summary alarm relay will pick.
When this switch is turned off, if a zone goes into alarm, only the zone alarm relay for the zone that is in
alarm and the summary alarm relay will pick.
1 = Individual Zone Alarm Relays Linked
0 = Individual Zone Alarm Relays Not Linked (factory default)
2-2.4 SW1, Position 4: Zone Relays Supervised / Unsupervised
Configures the individual Zone Alarm Relays as supervised or unsupervised. If a relay is supervised, the
relay picks until power goes off or until an alarm is detected. The alarm then releases to announce a change
in state. An unsupervised relay picks only when an alarm is detected.
1 = Supervised
0 = Unsupervised (factory default)
2-2.5 SW1, Positions 5: Leak Alarm Delay
Designates the unit’s leak delay time. Setting this switch to off uses the default leak alarm delay of 15
seconds. Setting this switch to on designate the leak alarm delay to use the value specified through the
unit’s craft port.
1 = Leak Alarm Delay set through Craft Port
0 = Leak Alarm Delay set at 15 seconds (factory default)
2-2.6 SW1, Positions 6: Summary Relay Silence-Ability
Configures the Summary Alarm Relay as silence-able or not silence-able. If the Summary Alarm Relay is
silence-able, the relay returns to normal when the Quiet/Test/Reset button is pressed. If the Summary
Alarm Relay is not silence-able, the relay stays picked until the alarm condition is cleared.
1 = Summary Alarm Relay is Silence-Able
0 = Summary Alarm Relay is Not Silence-Able (factory default)
