Inspection & Maintenance

A concise reminder of routine user checks, periodic servicing and record-keeping.

Routine attention

Daily
Confirm the control equipment shows normal operation or that displayed faults are being handled.
Weekly
Operate a different manual call point and confirm the expected response.
Periodic
A competent person inspects and tests a proportion of the system at intervals no longer than the stated maximum.
Across 12 months
The programme should cover every device and the system as a whole.

Record tests, alarms, faults and work in the system logbook. Non-routine attention is also needed after a fire or when false-alarm performance is unacceptable.
