Delay Override - Active at access level 1 and above
Used to override the delays to outputs programmed into the FACP. Override is only active when
the delay timer is active (delay active indicator flashing). Pressing will override the delay and
cause the alarm and ancillary outputs to be immediately activated.
Silence / Resound Alarms - Active at access level 2
Used to turn off the alarm outputs once they have been operated by a fire or evacuate condition.
In the event of a new fire condition the alarm outputs will again operate. Pressing a second time
reactivates the Alarm outputs once they have been silenced.
Silencing an alarm will cause the Common Fire LED and any Zone Fire LED to change from
flashing to steady.
Silence Buzzer - Active at access level 1 or above
Used for silencing either the fault or alarm warning buzzer at access level 1 and above. The
buzzer will resound on any new event.
Reset - Active at access level 2
The reset control is used to return the FACP back to a quiescent state from a fire alarm or fault
condition and to extinguish the “System Fault Indicator”. This means all zone circuits are reset for
2 seconds.
As a result of the reset, all alarm outputs, and fire output will be switched off, and the door holder
outputs activated
Where a fault condition is cleared as a result of a reset, and if the fault condition is still prevailing,
it shall be appropriately reflected at the FACP within 20 seconds. The fault conditions that are
cleared by Reset are system fault and any zone related faults. All other faults are non latching
The reset button is unique and is not to be used for any other purpose.
Note: Reset is also used to extinguish the System Fault indicator.
Evacuate - Active at access level 2
Turns on and latches alarm outputs, fire output and local buzzer and the common Fire indicator
flashing. The door holder outputs are switched off. No other outputs or indicators are affected.
Activating the silence / resound alarms control, will turn off the alarm outputs, and cause the
common fire LED to go steady. Activating the silence / resound again will cause the alarm
outputs to be activated and common fire LED to flash.
Operation of the silence/resound control has no effect on the door holder output state
Activating the reset switch, will cancel the evacuate condition, which results in the alarm outputs
being turned off, door holder outputs activated and the common fire led being extinguished.
Next - Active at access level 1 and 2.
At access level 1, the Next key is used to enter the 0 digit of the 3210 password.
At access level 2, the Next key is used to select zone circuits for the walk test and outputs for
disable / re-enable.
