Configuring strobes as Normal does not use a sync protocol for the output circuit.
•
Silenceable or non-silenceable.
Synchronized
Output circuits can be configured with various synchronization protocols.
When the output circuit is configured as strobe and also configured as non-silenceable and the
device used on the output is a combination of horn and strobe, then if the signal silence is
activated while the circuit is active the horn(s) are silenced while the strobe keeps on flashing.
Synchronized strobes and strobe/horn models of the following manufacturers are supported:
Mircom, System Sensor, Wheelock and Gentex.
5.3.3
Relay Output
Un-bypassed relay outputs are activated if any un-bypassed input circuit or common system
status which has been programmed to it is active. If the relay is configured as silenceable it is
inhibited when common auxiliary disconnect is active. Relays also turned off if they are
bypassed or if all inputs and system status correlated to the Relay Output are restored or
bypassed.

NAC Circuit Operation
NAC Circuits can be configured as
•
Signal Output
•
Strobe Output
•
Relay Output
For more information on Outputs see 5.3 Output Types.
Powered output circuits are supervised while they are not active for both open circuits and
shorts.
The circuit will not be activated if there is a short trouble on the circuit. It will be activated if an
open trouble is indicated. A circuit trouble activates the common trouble sequence as a non-
latching trouble. Since open circuit supervision does not operate while the circuit is in alarm, if
the circuit was in trouble before it was activated, it will still indicate trouble while active. The
trouble condition will be re-evaluated when supervision resumes.
Output circuits configured as strobes can have sync protocol for synchronization if configured.
Certain strobe and strobe/horns models of the following brands are supported:
•
Mircom
•
System Sensor
•
Wheelock
Note:
Silencing of the horn depends on the feature provided by the manufacturer of the
horn/strobe combination. Some models of the horn/strobe combination may not
have this feature and will not work as described above.
