Fire Alarm Installation in Ajax
Harex provides every service in Ajax: inspection, testing, repair, installation and verification, with the 24-hour emergency line answered for Ajax buildings at any hour.
Ajax Fire and Emergency Services runs a dedicated Fire Prevention division whose inspectors inspect occupancies under the Ontario Fire Code and also review site plans and architectural drawings for compliance, which matters on an installation or a change of use. The service has about 100 full-time staff across three halls.
Ajax Fire and Emergency Services' prevention inspectors review site plans and architectural drawings, not just finished installations. On an Ajax installation or change of use, Harex works to the drawings the Town has already seen, so the S537 verification matches what was approved.
Ajax has a growing logistics industry and an innovation district in development. Ajax West, with Pickering East, forms one of the Region's three Provincially Significant Employment Zones.
Harex forwards every completed fire alarm installation report for a Ajax building to Ajax Fire and Emergency Services, so the building is on record as maintained with the department that would otherwise be the one to notice a lapse. Ajax is about 22 minutes from the Harex base in Oshawa; travel is billed, and a three-year contract fixes the rate for its term.
Harex also provides fire alarm installation in Whitby and Pickering.
When you need this
Harex installs and verifies for a new build or addition, a change of use that puts your building under a stricter requirement. A panel that is obsolete, unsupported, or failing inspection year after year. Or a retrofit order from the fire department that you have decided to comply with.
How a project runs
- P-01Site review and scope.We walk the building, read the drawings or the order, and write the scope in plain terms with a fixed price.
- P-02Install to CAN/ULC-S524.Devices, wiring, annunciation and panel, staged around your operations so the building keeps running.
- P-03Verification to CAN/ULC-S537.Every device and every function proven and documented. This is the report the building official and your insurer want to see.
- P-04Handover and first annual.Staff shown how the panel behaves, records filed, and the building put on the annual inspection schedule so the clock never runs out.
Install or repair, honestly
We would rather repair a working system than sell you a new one. Where a panel still has parts and service life, we say so. Where it does not, we show you the deficiency history that proves it. And where a retrofit order looks unreasonable for a system that has passed for twenty-five years, we put that question to the fire department first. How we handle orders and disputes →

What clients say
across every platform
“Harex has looked after our alarm and extinguishers for years. They come when they say they will, and the report is in our hands before the insurer asks for it.”
“We were told the whole system had to be replaced. Harex asked the fire department why, in writing, and the scope came back a fraction of what we had been quoted.”
“We had thirty days and a list we did not understand. They went through it item by item, told us what was actually required, and we passed the re-inspection.”
“Four buildings, one schedule, one set of reports. I stopped chasing three different contractors for paperwork the month we switched.”
“Panel went into trouble on a Saturday night. Somebody answered, walked our supervisor through it on the phone, and had a technician there before the shift started.”
“We were told the whole system had to be replaced. Harex asked the fire department why, in writing, and the scope came back a fraction of what we had been quoted.”
