Fire Alarm Repair & Maintenance
24/7 emergency response · CFAA-certified technicians · Every major panel platform serviced.
What is Fire Alarm Repair & Maintenance?
Fire alarm repair and maintenance is the corrective work that gets a system out of trouble and back into supervised normal — clearing ground faults, replacing failed devices, swapping batteries, reprogramming panels and isolating wiring faults. A fire alarm panel showing trouble is not a code-compliant fire alarm system; the Ontario Fire Code requires faults to be cleared promptly.
First National Fire Protection provides 24/7 fire alarm repair and maintenance across Ontario. Our CFAA-certified technicians arrive prepared with diagnostic equipment, replacement modules and batteries for every major panel platform — Mircom, Edwards, Notifier, Honeywell, Simplex, Bosch, DSC, Napco — so most trouble conditions are cleared on the first visit.
From single device replacements to full panel swap-outs and addressable conversions, our fire alarm repair team handles the full corrective scope and re-verifies the system to CAN/ULC-S537 where required.

Ontario Fire Code & Insurer Requirements
An uncleared trouble condition on a fire alarm panel is itself a code deficiency under the Ontario Fire Code and CAN/ULC-S536. AHJs routinely cite buildings whose panels show trouble at inspection. Fast, certified fire alarm repair is the difference between a clean re-inspection and a notice of violation.
Insurers expect prompt fire alarm repair when troubles are identified. Delayed repairs can lead to coverage gaps that don't show up until a claim is denied.
- CAN/ULC-S536 — Inspection and Testing of Fire Alarm Systems
- CAN/ULC-S537 — Verification of Fire Alarm Systems
