14. Changes on the Detection Loop
14.1 Typical Scenarios
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.
14.2 Remove a unit and Insert the same unit
Scenario during normal operation /
actions to be carried out Panel indication (visual/audible)
For example, remove an optical smoke detector BH-300 and replace the same one.
1
Remove the detector from its base. Observe fault warnings “Open Circuit in negative wire” and
“Loop Unit not responding”
2
Acknowledge all faults. Buzzer off, indicator to steady
3
Insert the same detector. No change
4
Operate reset. Panel to quiescent condition.
