Changes on the Detection Loop

14. Changes on the Detection Loop

14.1 Typical Scenarios

14.2 Remove a unit and Insert the same unit

Scenario during normal operation /
actions to be carried out
For example, remove an optical smoke detector BH-300 and replace the same one.
1
Remove the detector from its base.
2
Acknowledge all faults.
3
Insert the same detector.
4
Operate reset.

This chapter provides information on how changes on the
detection loop affect the system during normal operation.
The table below gives an overview of typical scenarios for various
examples, including the actions to be carried out and the panel
indication (visual/audible).
Note that some fault messages may not appear if a change is done
rapidly (for example, a unit is removed and another unit is inserted
rapidly). However, the procedures will be the same, regardless of
how quick the changes are done.
Before a point is to be added or removed from the loop (for
example, a new detector base for a detector is added or an
existing is removed), the detection loop in question has to be
disabled after entering service mode. When the change has been
done, the detection loop has to be enabled.
Panel indication (visual/audible)
Observe fault warnings "Open Circuit in negative wire" and
"Loop Unit not responding"
Buzzer off, indicator to steady
No change
Panel to quiescent condition.
