12 1X-X3 Operation Manual
Extinguishing preactivation
The control panel is in the extinguishing preactivation state when:
• One fire detection zone in the extinguishing area goes into fire alarm and the
system is configured so that a second zone in the extinguishing area is
required to activate the extinguishing event.
• Extinguishing event conditions are detected (one or two zones go into fire
alarm depending on configuration) but manual mode is activated or a fault or
disable condition of an extinguishing device is preventing activation.
• The start manual call point is pressed but a fault or disable condition of an
extinguishing device is preventing activation.
The extinguishing preactivation state is indicated as follows:
• Preactivation LED: Flashing red LED.
• Zone LEDs: Flashing red (for zones in fire alarm). Note that these will always
flash (indicating detector alarms) for extinguishing detection zones, as these
zones are considered to be automatic.
• General Fire Alarm LEDs: Flashing for detector activation. Steady for MCP
activation.
• Fire Sounders Start/Stop LED: Steady, as the fire sounders are activated
immediately and any configured delay is bypassed.
• Fire routing indications are shown in the usual manner, linked to the fire alarm
event.
The control panel buzzer sounds continuously.
Extinguishing event prevented
When the control panel is in standby, fire alarm, or extinguishing preactivation,
the extinguishing event is automatically prevented (in effect, the extinguishing
event is disabled) for any of the following:

Disabled extinguishing sounder, extinguishing release optical warning panel
or sign, or releasing actuator

Fault in hold or abort extinguishing manual call point, extinguishing sounder,
extinguishing release optical warning panel or sign, safety door monitoring
(status or wiring), or releasing actuator.
The extinguishing event is enabled automatically (with a short delay) when the
disabled feature is enabled.
The extinguishing event is enabled automatically when the fault is fixed and the
control panel is reset.
A prevented extinguishing event is indicated by a flashing yellow Preactivation
LED and by the fault/disabled LED of the device that prevented the event.
