Range Guard SPDT Micro Switch for A Plus 9197227

The Range Guard 9197227 is a single-pole, double-throw (SPDT) micro switch for Range Guard A+ kitchen fire suppression systems. In plain terms, this is the small electrical switch that tells other equipment — like your exhaust fan or cooking appliance — to shut off the moment the fire suppression system fires. When the Range Guard system activates, the control head trips this switch, which then cuts power to one connected piece of equipment. It's how your system automatically turns off the fryer or fan when the suppression kicks in, which is required by fire code.

NFPA 96 — the standard that governs commercial kitchen fire safety — requires that gas and electric cooking equipment be automatically shut off when the suppression system discharges. The 9197227 SPDT switch is the electrical link that makes this happen in Range Guard A+ systems. The "single-pole" design means it controls one circuit — perfect for installations where you only need to shut off one piece of equipment or trigger one alarm signal. If your kitchen needs to shut down multiple pieces of equipment simultaneously, see the DPDT version (9197228), which controls two circuits at once.

This is an OEM part designed specifically for Range Guard A+ systems. It gets tested at every six-month inspection per NFPA 17A and NFPA 96 to make sure it actually fires when the system does — a switch that doesn't trip is an immediate inspection failure. Available through authorized Range Guard distributors. If your Range Guard system isn't shutting off your cooking equipment when it activates, a failed micro switch is one of the first things a technician will check.

Six-Month Inspection Test

Every Range Guard kitchen fire suppression system must be inspected every six months per NFPA 17A and NFPA 96. Part of that inspection is triggering a simulated system discharge and verifying the 9197227 switch actually fires and cuts power to the connected equipment. If the switch doesn't trip, or if the connected equipment doesn't shut off, the system fails inspection and must be repaired before the kitchen can be considered compliant. The inspector will note any failed switch on the inspection report and the issue must be corrected immediately.

Wiring

The 9197227 is wired into the Range Guard control head and connected to the circuit you need to shut off — typically an exhaust fan motor, cooking appliance power supply, or fire alarm panel input. Wiring must be done by a qualified technician following the Range Guard A+ system wiring diagram. Always wire the SPDT switch per the Range Guard system manual to ensure it functions correctly during both the inspection test and a real fire event.

What's the difference between the SPDT (9197227) and DPDT (9197228) switch?

The SPDT (single-pole) controls one circuit — for example, shutting off just the exhaust fan. The DPDT (double-pole) controls two independent circuits at the same time — for example, shutting off both the exhaust fan and the fryer power simultaneously. If your kitchen only needs one thing shut off automatically, use the SPDT. If you need two things shut off at once, use the DPDT. Your Range Guard system installer or inspector can tell you which your specific system requires.

My cooking equipment isn't shutting off when the system activates. Could this be the switch?

Yes, a failed or improperly wired micro switch is a very common reason cooking equipment doesn't shut off during system activation. During your next semi-annual inspection, the technician will test this switch specifically. If it's found to be faulty, it needs to be replaced with a new OEM 9197227 from an authorized Range Guard distributor before the system can pass inspection.
