Nac Programming - GE EST iO64 Technical Reference Manual

Chapter 3: Programming

NAC programming

The NAC circuits connected to your system must be programmed
with the type of NAC, label, correlation groups, and event
notification. Each NAC must be programmed separately.

Select either Class A or Class B.
Note: NAC 3 and 4 cannot be set to Class A. If NAC 1 and 2 are set to Class A, NAC 3 and 4
automatically configure to accept the Class A return.
Set NAC type to:
Continuous (silenceable or nonsilenceable): For strobes and notification appliances that self-
generate a temporal pattern
Temporal (silenceable or nonsilenceable): Universal 3-3-3 pattern required for evacuation
signals by NFPA 72. Used when notification appliances are not capable of self-generating a
temporal pattern.
Genesis (nonsilenceable or with audible silence or with audible/visible silence): Used with
Genesis and Enhanced Integrity horns and strobes. Genesis and Enhanced Integrity appliances
maintain synchronization per UL 1971.
Nonsilenceable: Horns cannot be silenced and strobes flash
Audible silence: Horns can be silenced while strobes continue to flash
Audible/visible silence: Horns can be silenced and strobes can be turned off
Coder (basic, continuous, 120 SPM, or temporal): Used to provide 4-digit coded output in
response to alarm conditions. When the device goes into alarm, the coded output is played a
minimum of four times by the NAC circuit. The code comes from the active initiating device or
zone. Note: The panel can only play one code at a time. For example, device 1 is coded as 1-2-
3-4 and is associated with NAC1 and device 2 is coded as 5-6-7-8 and is associated with NAC2.
If device 1 activates, NAC1 plays 1-2-3-4. If, while NAC1 is playing 1-2-3-4, device 2 activates,
NAC2 will also play 1-2-3-4 until the rounds are complete and then both NACs will play 5-6-7-8
until those rounds are complete. If you are programming NACs as coded, remember that only
one code can play at a time.
Basic: Four rounds of the 4-digit coded output are played
Continuous: Four rounds of the 4-digit coded output are played and then continuous is
played
120 SPM: Four rounds of the 4-digit coded output are played and then 120 times per minute
is played
Temporal: Four rounds of the 4-digit coded output are played and then a temporal pattern is
played
City tie: Outputs an unsynchronized, 24-volt continuous (steady) signal that cannot be silenced.
Select this NAC type when the NAC is connected to a city tie module.
Enter a text label for the NAC (up to 40 characters and two lines). When finished, choose Save.
Select the correlation group that you want to correlate/assign the NAC to. Select Yes to add the
NAC to the correlation group or No to not add the NAC to the correlation group. When finished,
choose Save.
Note: A correlation group is a collection of NACs and/or output devices (strobe) that responds
to an input device (smoke detector). When you program the loop devices, you will have to
correlate/assign the desired input device or zone to the correlation group that you want to
activate. Refer to "Correlation groups programming" for more information.
