Exhaust, make-up air and suppression-trip sequencing
The control sequence starts with the listed equipment documentation and approved ventilation and suppression design. Normal cooking operation and a suppression-system trip are different states. Required actions can involve exhaust fan operation, make-up air changes, fuel shutoff, and electrical disconnection of protected cooking appliances. Do not apply a diagram from a different restaurant to an unfamiliar hood. The expected response of each piece of equipment must be established before wiring or altering the controls.
EmergenServe handles the agreed electrical wiring and interfaces, coordinating with the mechanical and fire-suppression specialists for their portions of the system. A shunt-trip breaker, contactor, relay, or control-panel connection must match the actual design and equipment ratings. Electrical corrections alone cannot certify a suppression system or resolve ventilation, duct, structural, or fuel-system deficiencies outside the contracted electrical scope.
