Quick answers

Does TMFAD allow the original alarm repair to be deferred?

The original system still needs prompt repair. While TMFAD is in use, follow up the repair date, parts and testing so the shutdown stays as short as practicable.

Legal information

Requirements vary by premises. Confirm the work with the responsible professional using the premises use, approved plans, licence conditions and any written directions.

Match the temporary measure to the lost function

TMFAD is a temporary standby measure when the fire alarm is not in efficient working order. Circular 6/2026 took effect on 1 September 2026 and is read with the shutdown arrangements in Circular 1/2021.

Continue repairs to the original system while temporary devices are in use. Ask the contractor to explain the affected functions, precautions and expected repair date, so management knows when normal service can resume.

Use the required contractor and on-site tests

The circular requires a Class 2 registered contractor to install compliant temporary devices beside each existing manual call point in the affected area, complete on-site testing and follow the applicable FS251 process. Ask for a list of device positions and quantities.

Ask the quote to identify quantities, positions, power arrangements and routine responsibilities, with confirmation that the selected device meets the specification. Include operating information and fault reporting in staff handovers.

Track temporary provision alongside repair progress

Keep a list of temporary-device locations, test results, contacts and progress on the original alarm repair. Report low-battery or fault indications promptly to the designated contact, following the agreed arrangements.

After repairing the original system, have the contractor test it, confirm normal operation and decide when the temporary alarms can be removed. Management should not remove them independently on the original planned completion date.

Practical checklist

  • Identify alarm failure and affected areas
  • Check contractor class and device specification
  • Record positions, power and testing
  • Assign routine checks and a fault contact
  • Track original-system repair and reinstatement

Discuss alarm repairs and temporary measures

Share the affected area, existing call-point positions and management contact to help us review the site and repair coordination.

  • Review faults and original-system repair scope
  • Assess temporary-measure and installation needs
  • Testing, documentation and reinstatement follow-up
