Procedures
Each digital display module is supplied with
two separate output relays. One relay for
high line pressure alarm and another for
low line pressure alarm.
Each relay has a set of dry, normally-
closed contacts that will open when an
alarm is activated on corresponding front
panel signal.
For example, when a low pressure alarm
condition activates on digital display
module front panel, relay labeled “Low
Relay” will activate, opening its contacts.
Relay contacts will remain open as long as
alarm condition is active, even if audible
alarm is silenced by MUTE
button.
When alarm condition is corrected, relay
contacts will close.
Relay contact ratings are 2 A @ 30
VDC/0.5 A @ 125 VAC.
Refer to
Wiring Schematic 9 (Page 53).
General Fault / Aux Relays
Annunciator Module General Fault Relay:
The annunciator module is supplied with
an alarm panel general fault output relay.
This relay has a set of dry contacts that
may be wired either normally open or

The relay will activate when ANY alarm on
ENTIRE alarm panel is activated. Relay
will remain activated as long as alarm
condition is active, even if audible alarm is
silenced by MUTE
button.
When alarm condition is corrected, relay
will deactivate. Relay contact ratings are 2
A @ 30 VDC/0.5 A @ 125 VAC. Refer to
Wiring Schematic 8 (Page 53).
Annunciator Module Auxiliary Relay:
The annunciator module is supplied with
an additional auxiliary relay.
Auxiliary relay has a set of dry contacts
that may be wired either normally open or
normally closed.
Auxiliary relay will activate when ANY
alarm on ENTIRE alarm panel is initiated.
Auxiliary relay will deactivate when audible
alarm is silenced by MUTE
button.
If alarm condition is still active when mute
function cancels, auxiliary relay will
reactivate.
Relay contact ratings are 2 A @ 30
VDC/0.5 A @ 125 VAC. Refer to Wiring
