11.2.4 How the Panel Works in Mode 2
• Activation of either Z-1 or Z-2 turns NAC-1 on steady.
• Activation of either Z-1 or Z-2 changes the Hazard Area 1 state from Idle into Alarm
directly. NAC-1 turns on steady. NAC-2 turns on Temporal. Release Timer-1 is started.
• Expiration of Release Timer-1 activates both RAC-3 and RAC-4. NAC-1 and NAC-2 turn
on steady.
• Activation of Z-6 starts Manual-release Timer 1 (MDT-1) in any situation. NAC-1 turns on
steady. NAC-2 turns on Temporal. Upon the expiration of MDT-1, RAC-3 and RAC-4
turn on.
• During Hazard Alarm state, after Z-5 (abort switch) is pressed, Release Timer-1 will
reset and then restart. If Z-5 is held for any time up to 50 seconds, then the releasing
device will actuate 60 seconds after the switch is pressed. However, if Z-5 is held for
longer than 50 seconds, then the releasing device will actuate 10 seconds after the
switch is released.
• Activation of Z-3 turns both NAC-1 and NAC-2 on steady.
• Activation of Z-4 can be indicated on NAC-2 at 20BPM, if enabled.
