NAC Temporal/Steady Programming - Section 1 (‘NAC1’ LED on steady)
You can individually program both NAC1 and NAC2 to sound in either a temporal or steady pattern. By

Temporal
The NAC1 will sound the Temporal/ANSI Fire Pattern: 0.5 seconds ON, 0.5
seconds OFF, 0.5 seconds ON, 0.5 seconds OFF, 0.5 seconds ON, 1.5
seconds OFF, repeat.
The NAC2 will sound the Temporal/ANSI Fire Pattern: 0.5 seconds ON, 0.5
seconds OFF, 0.5 seconds ON, 0.5 seconds OFF, 0.5 seconds ON, 1.5
seconds OFF, repeat.
Steady

The NAC2 will sound continuously.
NAC Auto-silence and Strobe Programming - Section 2 (‘NAC2’ LED on steady)
Automatic Signal Silence
If Automatic Signal Silence is enabled, 30 minutes after the last fire alarm on
the system, the panel restores the NACs to normal (alarms are silenced).
If another alarm occurs after the NACs are silenced, the panel will restart the
timer for another 30 minute period.
If Automatic Signal Silence is disabled, the panel will not silence the NACs
automatically.
NAC2 Strobe
If this option is enabled, on alarm, NAC2 turns on steady and does not turn
off on automatic signal silence, or when the Silence Alarm button is pressed.
When NAC2 is set to this mode, it can only be turned off when all zone fire
alarms are restored, and the system is reset. Only NAC2 can be set to this
mode.
If this option is disabled, the panel will restore NAC2 to normal following an
automatic signal silence (see Automatic Signal Silence, above), or following
a press of the ‘Silence Alarm’ button.
