Bill says: I'm working on a fire alarm for my engine compartment. I figure that I will install a heat sensor/switch in the engine compartment and wire it to a buzzer or siren. In order to avoid false alarms, I need to know the MAXIMUM temperature that will occur in the engine compartment under normal operating conditions (no fire) in, let's say, the Arizona desert in July. I would then use a heat sensor/switch rated just above that maximum engine compartment temperature. Ideally I would like an actual measured maximum temperature, but estimates are welcome too. Please specify weather your response if measured or estimated. ----------- On my 82 air cooled I have an adjustable thermostat that switches on and off the aux. oil cooler fan when the oil hits 220. At 220 the thermostat is about in the middle of the adjustment. You could use something similar and adjust it up until the false alarms stop occurring. If a fire occurs your alarm might work until the themostat cooked. By then you would have hit the inject CO2 button and the switch to seal off the engine compartment. Is it Friday yet?
