Digital Display Module Master/Slave
Digital display modules of two alarm
panels may be wired together in such a
way that pressure readings of first panel
can be duplicated at second panel.
Each digital display module has RS-422
digital outputs and inputs. By connecting
digital output (master output) of first panel
to digital inputs (slave input) of the
second panel, second panel will duplicate
pressure readings.
Connect the master output terminals of
the sending digital display module to the
slave input terminals of the receiving digi-
tal display module.
Refer to
Wiring Schematic 6 (Page 51).
As an option, mutli-signal modules may be
ordered with five output relays, one for
each of five signals that multi-signal is
capable of monitoring.
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 an alarm
condition activates on top multi-signal front
panel alarm location (Signal 1), relay
labeled “Signal 1” 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.
