I am considering a Honeywell 5809 for the garage. Its a heat sensor with capabilities to measure rate of rise. The ‘heat’ zone on the 2gig heat/smoke detector only seems to measure temperature. The RE205/RE219 also seem to measure temperature.
Has anyone ever used a 5809 on a 2gig system? Is this a good solution to monitor for fire in a garage? Perhaps a kitchen as well or near the furnace? In reading about heat detectors it seems you want to monitor a fixed temperature in some situations and rate of rise in others.
FYI in my research I found out something interesting by contacting Resolution Products. The RE219 manual says ‘NOTE: Sensor reacts within 3 seconds when cover is off; 30 seconds when cover on.’ The RE205 doesn’t have this note, I contacted Resolution Products and they said the RE205 will react immediately. The Honeywell 5821 environment monitor says the high temp condition needs to exist for 10 minutes before it will trip!
