Household smoke alarms
Use the test control and confirm the expected warning
GOV.UK recommends testing smoke alarms at least monthly. Press and hold the test control as instructed until the alarm sounds; check linked alarms and specialist warning devices where provided.
If the alarm does not sound, follow the model instructions for battery or unit replacement. Never use a naked flame, smoke source or improvised aerosol to test a household alarm.
Workplace call points
Plan a short controlled test that does not create a false response
Use the premises procedure: notify occupants, reception, security, monitoring centres and other affected parties as required. Use the proper test key at a manual call point and verify panel indication, sounders or other outputs expected from the weekly user test.
Rotate the call point used on successive tests so devices are sampled over time. The system design and maintenance instructions determine the appropriate arrangement.
- Authorised tester identified
- Monitoring and affected parties notified
- Correct test key and logbook available
- Expected panel zone and warning confirmed
- Faults and unwanted effects recorded
- System returned to normal and parties informed
Scope boundary
A user test does not replace competent inspection and servicing
Pressing a domestic test button does not prove perfect sensing under every fire condition. Operating one workplace call point does not inspect every detector, circuit, battery, interface or sound level.
Arrange competent periodic inspection and maintenance for the system and act promptly on faults, disablements and repeated unwanted alarms.
If the test fails
Record, assess and restore protection
Record the device, zone, time, result and indication. Tell the responsible person or landlord and arrange the appropriate repair or replacement.
Where warning is impaired, assess the immediate risk and introduce suitable interim measures until protection is restored. Do not quietly cancel or omit future tests because faults are inconvenient.
