5.3.2.1 Strobe Synchronization Silencing Option
When a NAC cadence pattern is configured as Gentex built-in synchronization, the panel behavior during
system silence can be configured to leave the strobes on while silencing the horns or the panel can
silence both the horns and strobes.
The first programming screen for the NACs sets up the strobe silencing characteristics for circuits
programmed with the Gentex cadence pattern.
Strobes left on
for silence: No
When this programming option is Yes, Gentex strobes will be left active if
the NAC is configured as silenceable. When No, both horns and strobes
will be silenced.
5.3.2.2 NAC Silencing Attributes
The next programming screen for the NAC outputs sets up the silencing characteristics for circuits
programmed as FIRE NAC. Each output configured as a NAC circuit from the zone mapping can be
configured as silenceable or not silenceable when the silence key is pressed. In the screen below press
the number keys 1, 2, 3 or 4 to toggle the silenceable characteristics for circuits 1, 2, 3 and 4. Press Enter
to accept the selections when complete. The silenceable option has no effect on circuits not programmed
as FIRE NAC from the zone programming menus. Note also that input zones configured as type FIRE
can also be configured as silenceable or not silenceable. A NAC is only silenceable if it is configured as
silenceable and all active FIRE zones that triggered the NAC are also silenceable.
SILENCEABLE NACs
--3-
In this example, the screen shows that only NAC circuit 3 is
silenceable. Circuits 1, 2 and 4 are not silenceable.
5.3.2.3 Assigning Outputs to the Resettable Auxiliary Power Function
NACs that will be used as resettable 24VDC power need to be selected in the AUX RESETTABLE
programming screen. In the programming screen below press the number keys 1, 2, 3 or 4 to toggle
whether circuits 1, 2, 3 or 4 are used for resettable auxiliary power or not. Press Enter to accept the
selections when complete. Circuits programmed as resettable power will have continuous 24V power
present except for 10 seconds when the reset key is pressed.
AUX RESETTABLE
-2--
In this example, the screen shows that only NAC 2 has been
assigned a resettable power function. Circuits 1, 3 and 4 are
used for other functions.
5.3.2.4 Assigning Outputs to the Continuous Auxiliary Power Function
NACs that will be used as constant 24VDC power need to be selected in the AUX CONTINUOUS
programming screen. In the programming screen below press the number keys 1, 2, 3 or 4 to toggle
whether circuits 1, 2, 3 or 4 are used for continuous auxiliary power or not. Press Enter to accept the
selections when complete. Circuits programmed as continuous power will always have power present
even when running on battery backup unless the circuit has an over current fault trouble.
AUX CONTINUOUS
--3-
In this example, the screen shows that only NAC 3 has been
assigned a continuous power function. Circuits 1, 2 and 4 are
used for other functions.
5.3.2.5 Assigning Outputs to the Door Holder Auxiliary Power Function
NACs that will be used as door holder 24VDC power need to be selected in the AUX DOOR MAGNETS
programming screen. In the programming screen below press the number keys 1, 2, 3 or 4 to toggle
whether circuits 1, 2, 3 or 4 are used for door holder power or not. Press Enter to accept the selections
