Reliable Fire Suppression Systems Markham for Your Facility

Markham’s technology sector relies entirely on clean agent fire suppression. A water sprinkler discharge in a Markham data centre or sensitive biotech lab would cause more financial devastation than a localized fire. Facilities along Highway 7 require advanced suppression systems utilizing FM-200, Novec 1230, or inert gases (like Inergen) that extinguish fires rapidly without leaving residue, damaging electronics, or harming personnel. Markham Fire and Emergency Services expects rigorous maintenance of these systems, including semi-annual inspections and room integrity testing. SESSI is Markham’s premier partner for mission-critical clean agent suppression design and life-cycle maintenance.

FM-200 (HFC-227ea) — A clean agent that suppresses fire without leaving residue. Safe for occupied spaces and electronics.
Novec 1230 — A clean agent with zero ozone depletion potential and a short atmospheric lifetime. Common in data centres.
CO2 Systems — High-concentration carbon dioxide systems for unoccupied industrial hazards such as printing presses and turbines.
Wet Chemical Systems — Specifically designed for commercial kitchen hoods and cooking equipment. Required by NFPA 17A.
Dry Chemical Systems — Powder-based suppression for flammable liquid and industrial hazards.
Inert Gas Systems — Nitrogen, argon, or IG-55/IG-541 blends that reduce oxygen concentration without leaving residue.

Fire Suppression Systems Markham — Frequently Asked Questions

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

Both Novec 1230 and FM-200 are highly effective for Markham data centres. FM-200 has a long track record of reliability, while Novec 1230 has a near-zero global warming potential, making it the preferred choice for companies with strict environmental/ESG mandates. SESSI designs and services both systems.

Inergen is an inert gas mixture (Nitrogen, Argon, CO2) that suppresses fire by lowering the oxygen level in the room just enough to extinguish flames, while remaining perfectly safe for human breathing. It is often used in Markham archival storage, large data halls, and telecom facilities where chemical agents are not preferred.

SESSI performs an NFPA 2001 room integrity test by installing a specialized fan in the Markham server room doorway. We pressurize the room to measure leakage through cable penetrations, walls, and HVAC vents. If the room leaks too much, the clean agent gas will escape before suppressing the fire. We provide sealing recommendations if the test fails.

NFPA 2001 requires semi-annual inspection of clean agent systems in Markham, including verifying cylinder pressure and agent weight. Every 5 to 12 years (depending on the agent and cylinder type), the cylinders must undergo hydrostatic testing or internal visual inspection. SESSI tracks and manages these critical compliance dates.
