Subsequently pressing/releasing the abort switch repeats the process (silencing the NACs, activating the bell, starting the 90 second
investigation timer, etc.) until the Release Timer expires and the RAC(s) activate.
Pressing/releasing the Abort switch while the Investigation Timer counts down, has no effect.
Use of the abort switches in a pre-action or deluge water type releasing service will void UL 864 Listing for this product.
• Immediate. If a confirmed alarm exists, for example two detectors on separate zones for a cross zoned system or a single detector in
a single alarm system, the RACs activate immediately upon release of the abort switch.
• 10s/Remaining. When the abort switch is released, the delay used is whichever is greater - the remaining time left on Automatic
Release Delay Timer or 10 seconds.
• IRI Abort - Cross Zoned System Only (Does not comply with UL 864). When a single alarm is present, pressing the abort switch
prevents the RACs from activating. If a second alarm condition occurs while the abort switch is still pressed, the automatic release
timer resets to whatever value has been configured for it and begins to count down, stopping at 10 seconds. When the abort switch is
released, the panel starts the release timer countdown.
• Original Delay (Does not comply with UL 864). Releasing the abort switch resets the delay timer interval to the value set for the
Automatic Release Delay Timer.

6.10 Programming Stage 1 Alarm NAC2 Coding
The function of the NAC is to warn building occupants of alarm conditions detected by the system. Occupants must be familiar with the
established procedures to follow upon detection of an alarm. For systems intended for Halon 1301 (NFPA 12A), Halon 1211 (NFPA 12B),
or clean agent (NFPA 2001) release, a pre-discharge NAC must be configured to warn building occupants of the impending discharge. The
setting of the release timer selects the duration of the pre-discharge signal. Compliance with ADA requires audible and visible notification.
• Cross Zoned System. The first alarm sounds a temporal code (.5 second ON, .5 second OFF, .5 second ON, .5 second OFF, .5 second
ON, 1.5 seconds OFF, and then repeat pattern) on the audible NACs. The second alarm causes the cadence to increase to 120 beats
per minute for the duration of the Automatic Release Delay Timer. When release occurs, the audible appliances sound a steady tone.
