10.1.4 Hazard Release
• Panel enters Hazard Release when the Release Timer or Manual Release Timer
expires. The correlated releasing circuit is activated.
• NAC code for Hazard Release state is steady.
10.2

General Panel Operation

• Activation of Manual Release Switch starts the Manual Release Delay Timer. The
expiration of Manual-release Delay Timer (MDT) activates the releasing circuits
consequently. Manual Release Switch overrides the Abort Switch always and Manual-
release Timer (MDT) always overrides Release Timer (RT).
• When the manual release switch is active and the panel is in the Hazard Alarm (pre-
discharge) state, Abort Switch cannot override the Manual Release Switch. Only the
System Reset key can interrupt and reset the panel and hazard area.
• System Reset will reset all circuits, including releasing circuits.
• The supervisory circuit can be optionally indicated on NAC-2 circuit. The NAC code of
supervisory circuit should be different from those of Hazard Alert or Hazard Alarm. By
default, when the NAC code for Hazard Alert is Temporal, the NAC code for supervisory
circuit is 20 BPM or verse visa. This configuration change is automatically done by the
panel. If NAC code for alert is chosen other than 20 BPM and Temporal, Supervisory
NAC code will remain unchanged during the configuration.
• In some pre-programmed modes, the Alert Rate and the Alarm Rate are configured the
same. So the action of Abort Switch does not change the NAC rate.
