Option
Description
Type
Set the NAC type to one of the following values.
Continuous (silenceable or nonsilenceable): For strobes and
notification appliances that 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 generating a temporal
pattern.
Genesis (nonsilenceable or with audible silence or with
audible/visible silence): For Genesis and Enhanced Integrity
horns and strobes. Genesis and Enhanced Integrity appliances
maintain synchronization per UL 1971. When using Genesis or
Enhanced Integrity notification appliances, you must select one
of the Genesis NAC types for proper system-wide strobe
synchronization.
• Nonsilenceable: Horns cannot be silenced and strobes flash
• Audible silence: Horns can be silenced while strobes
continue to flash
• Audible/visible silence: For Genesis devices only,
connected horns can be silenced and strobes turn off
Coder (basic, continuous, 120 SPM, or temporal): Used to
provide four-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 four-digit coded output are played
• Continuous: Four rounds of the four-digit coded output are
played and then continuous is played
• 120 SPM: Four rounds of the four-digit coded output are
played and then 120 times per minute is played
• Temporal: Four rounds of the four-digit coded output are
played, and then a temporal pattern is played
Continuous Non-Silenceable (Latched): For programming NAC
as latched output
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.
