How often fire alarms
are tested in Ontario.
Since January 1, 2026, the Ontario Fire Code requires fire alarm systems to be inspected and tested to CAN/ULC-S536:2019, and new or modified systems to be verified to CAN/ULC-S537:2019.
| Frequency | What happens | Who does it |
|---|---|---|
| Daily | Check the control panel shows normal with no trouble signals. | Building staff |
| Monthly | Routine operational test set out in CAN/ULC-S536, for example activating one manual pull station on a rotating basis and confirming the alarm sounds. | Building staff or technician |
| Annually | Every device inspected and tested, batteries load-tested, results recorded on the standard ULC report forms. | Qualified fire alarm technician |
| After changes | New, extended or modified systems verified to CAN/ULC-S537 and a verification certificate issued. | Qualified fire alarm technician |
| Conventional | Addressable | |
|---|---|---|
| Reports alarms | By zone | By individual device |
| Finding the source | Search the whole zone | Panel shows the exact device |
| Best for | Smaller buildings with few zones | Multi-tenant, multi-floor and larger sites |
| Upfront cost | Lower | Higher |
| Expansion | Limited by zones | Add devices to the existing loop |

Fire alarm service across the GTA
How often do commercial fire alarms need to be inspected? +
Under CAN/ULC-S536 and NFPA 72, commercial fire alarm systems require annual professional inspection and testing by a certified technician. Monthly visual checks and supervisory-signal testing are typically required as well. Boss Fire can take over the full inspection schedule and deliver documentation your insurer and fire marshal will accept.
What's the difference between conventional and addressable alarms? +
Conventional systems group detectors into zones. When one triggers, the panel tells you the zone, not the exact device. Addressable systems identify the specific device that alarmed, which is critical in multi-tenant and multi-floor buildings where locating the source fast matters. Boss Fire recommends and installs both, depending on your occupancy.
Do you provide 24/7 alarm monitoring? +
Yes. Our partnered ULC-certified central station provides 24/7/365 monitoring for fire, intrusion, medical, and environmental alerts. When an alarm is triggered, trained operators dispatch the appropriate emergency service. Typically within 30-60 seconds.
Can you take over an existing alarm system? +
Yes. Boss Fire services most major manufacturers and takes over existing installations frequently. Including transferring monitoring to our certified central station. We'll audit the system, provide a compliance report, and give you a clear upgrade path if needed.
