Fire Alarm Inspection & Testing 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 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 inspection & testing 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 inspection & testing in Whitby and Pickering.
Who legally needs it
The Ontario Fire Code requires it for industrial, commercial and multi-tenant buildings with a fire alarm system, and Harex inspects to it across Durham Region. Your insurer requires current records to renew. The fire department's inspection division runs a rolling schedule, and a missed inspection is how a 30-day order to comply begins. Fines typically run $5,000 to $30,000, and the statutory maximums go far higher.
Frequency
Annual testing is the baseline for most Durham Region buildings Harex inspects, with monthly checks in between. Since January 1, 2026, annual inspections must follow CAN/ULC-S536:2019. Work typically sits under a three-year contract: a technician who knows your building, a locked rate, no lapses.
What we test
Every device. S536 does not permit sampling. Harex tests all of them. If a quote seems suspiciously cheap, ask whether all devices are tested.

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.”
