Outputs.
•
Detection Modes can be Stage 1 / Stage 2 Investigation Mode (see section 6) or Sensitivity Mode
(Detector sensitivity is adjusted at certain times of the day) or Alarm Verification Mode (The signals
from smoke detectors must be verified after a programmed period of time before a fire alarm is
raised). All of these modes are useful in reducing false alarms and will have been programmed by the
commissioning engineer to suit the requirements / use of the building.
•
The normal activation of these modes is based on a '7-day' clock timer to be active at specific times of day
or night. The clock timers can be overridden to turn on / off the operation manually. Starting the detection
mode will activate the function until it is next scheduled to turn off automatically. Ending the detection mode
will de-activate the function until it is next scheduled to turn on automatically. Note: If there are no 7-day
timers programmed, the enable / disable function simply turns on / off the detection mode programmed.
•
To end (disable) or start (enable) the operation of the detection mode, press '5' and the display
prompts for whether the detection mode should be started or ended depending in its current
operational state. For example:
Start Detection Mode
Press
End Detection Mode
Press
•
The detection modes available are programmed in the Level 3 Commissioning Mode Functions. If
there are no detection modes configured, this option has no effect.
•
Press the ' ' key to start / end the function, as appropriate.
•
Press the 'X' key to cancel and make no changes.
•
The "Delayed Mode" LED Indicator will illuminate when the detection mode is currently active and will
turn off when the detection mode is not currently active.
5.3.5.6

Disable / Enable Output (Pattern) Delays

•
Delays to sounder and other outputs may have programmed as part of a "phased evacuation plan" for
the building.
These delays should not normally be turned off (disabled), as this will compromise the
effective, safe evacuation of the building in the event of a fire.
•
To disable or enable the operation of any output delays, press '6' and the display prompts for whether
the delays should be disabled / enabled depending in the current operational state. For example:
Disable Delays
Press
Enable Delays
