What Happens During a Commercial Fire Alarm Service?

An engineer checks the panel, batteries, sounders and interfaces, tests a proportion of the detection devices so all are covered across the service cycle, verifies the cause and effect where relevant, and issues a written service record listing anything found.

Before the visit

Agree the date and the sounder testing window with the building, and let occupants know. Where the alarm is monitored, the Alarm Receiving Centre is put on test so a service activation is not treated as a real event.

On site

The engineer works through the panel and power supplies, then the field devices, then the outputs and interfaces such as door releases and plant shutdown.

  • Panel indications, event log and fault history
  • Standby batteries and charging
  • A proportion of detectors and manual call points, rotated across visits
  • Sounders and visual alarm devices for coverage and audibility
  • Interfaces and cause and effect where applicable

After the visit

You receive a service record listing what was tested and anything that failed, with the remedial work needed. Keep it with the log book and the certification in the fire safety file.
