• The activations of both Z-1 and Z-2 turn NAC-1 off, turn NAC-2 on at 120BPM, and turn
NAC-4 on steady. Hazard Area 1 state changes to Alarm. Release Timer-1 is started.
Upon the expiration of Release Timer 1, RAC-3 is active, NAC-1 and NAC-2 turn on
steady, and NAC-4 remains on steady.
• If Abort Switch Z-5 is active when Release Timer-1 is running, Hazard Area 1 state
changes to Alert. NAC-2 turns off and NAC-1 turns on Steady. Release Timer-1 is held.
• If Abort Switch Z-5 is released, NAC-1 turns off and NAC-2 turns on 120BPM. Release
Timer resumes running. Release Timer-1's value depends on Abort Delay Type.
• Activation of Z-6 starts Manual Release Timer 1 (MDT-1). Upon the expiration of MDT-1,
NAC-2 and NAC-4 turn on steady. RAC-3 is active.
• Activation of Z-4 is indicated at 20BPM on NAC-2, if configured.
