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 section 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
•
Secutron
•
System Sensor
•
Wheelock
For a complete list of compatible Horn/Strobes see section 9.1 MR-3318 Compatible Horn/
Strobes.
When configured as normal, the output circuit is ON continuously when activated and does not
use any sync protocol. When configured as non-silenceable strobes, the strobes cannot be
silenced, but the horn can be silenced by pressing the 'signal silence' button.
If the strobe is configured as silenceable strobe both the horn and the strobe are silenced
(stopped) by pressing the 'signal silence' button.
