It is possible to manually override (turn on / off) detection mode
delays.
•
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
