Fire Alarm Systems Markham — Frequently Asked Questions

Common questions about fire alarm systems Markham, inspections, and Ontario Fire Code requirements for Markham properties.

Data centres in Markham require very early warning fire detection (VEWFD) systems — typically VESDA (air sampling) — integrated with the building fire alarm panel, pre-action sprinkler control, HVAC shutdown, and ULC-listed monitoring. These systems detect combustion at the parts-per-million level, providing maximum time to evacuate and protect assets before suppression activates.

Biotech labs in Markham often produce chemical vapours that can false-trigger standard smoke detectors. SESSI specifies multi-criteria detectors (combining photoelectric and CO sensing) or aspirating systems that can be tuned to ignore lab-specific environmental conditions, reducing false alarms while maintaining reliable fire detection.

Yes. SESSI designs networked fire alarm systems for Markham tech campuses where each building panel communicates to a central annunciator — enabling security staff to identify the exact building and zone during an alarm. We manage the full network design, installation, and annual CAN/ULC-S536 inspection program.

All commercial fire alarm systems in Markham office parks require annual CAN/ULC-S536 inspection and testing. York Region mandates inspection compliance for all properties with over 100 occupants. Markham Fire and Emergency Services verifies inspection certificates during its annual commercial property audit program.
