Indicating (Signal) Circuits Types
Sprinkler Alarm
An alarm for sprinkler flow sensors. These alarms are identical to normal non-verified
alarms unless the water-flow retard operation is enabled. If water-flow retard
operation is enabled, then these circuits are sampled every one second; if ten
samples are active within any 15 second interval, the sprinkler alarm is confirmed and
processed. An alarm condition causes the associated circuit Status LED and the
Common Alarm LED to illuminate red.
Note: Do not use the retard operation with any external retarding device;
maximum retard may not exceed 120 seconds.
General Alarm
These alarms provide remote general alarm such as for remote key switches. In a two
stage system, these inputs perform exactly the same function as the front panel or
remote annunciator General Alarm button. In a single stage system, these inputs act
the same as non-verified alarms, but if correlations are enabled, general alarm
initiating circuits are correlated to
all
NACs.
Non-Latching Supervisory
These alarms are for supervisory devices. An activation on these circuits will cause
the Circuit Status LED and the Common Supervisory LED to illuminate amber. The
buzzer will sound continuously. If the circuit activation is removed, the supervisory
condition will clear (so long as there are no other supervisory conditions in the
system) and the circuit Status LED will extinguish.
Latching Supervisory
These alarms are for supervisory devices. An activation on these circuits will cause
the Circuit Status LED and the Common Supervisory LED to illuminate amber. The
buzzer will sound continuously. If the circuit activation is removed, the Supervisory
condition will
not
clear.
Monitor (BLDG)
This is a supervised general purpose non-latching input used mainly for correlating to
a relay circuit. No other system condition occurs as a result of its activation (short-
circuit), although it is supervised for trouble (open-circuit).
Trouble-Only
This circuit is used for monitoring a trouble condition from an external device such as
a Mircom Series 500 Audio System. Both open and short circuits generate a non-
latching trouble condition.
Indicating (Signal) Circuit
Type
Description
Silenceable Signal
For audible devices such as bells and piezo mini-horns that may be silenced either
manually or automatically. While sounding, these follow the pattern appropriate for
the condition: the configured evacuation code (default is temporal code) during
single-stage alarm, or two stage general alarm, or the alert code during a two stage
system's alert (first) stage.
Non-Silenceable Signal
For audible devices such as bells and piezo mini-horns that may not be silenced
either manually or automatically. While sounding, these follow the pattern appropriate
for the condition: the configured evacuation code (default is temporal code) during
single-stage alarm, or two-stage general alarm, or the alert code during a two stage
system's alert (first) stage.
Coded Signal
For audible devices such as bells and piezo mini-horns that may be activated in
code. The code consists of 4 digits with each digit consisting of 1-15 pulses on the
signals. Each coded circuit can sound the complete code 1 to 15 times after which
signals go silent or revert to programmed General Alarm rate.
Note: The NFPA-72 and ULC-S527 specify temporal tone. However, for retrofits
of systems that were previously approved, coded signalling is allowed.
Strobe
For visual devices such as strobes that use no code patterns (they are continuous).
