How do I setup low-temp & freeze detection on a 5808W3?
The Honeywell 5808W3 is a wireless smoke detector when programmed to loop 1. The device is also capable of low temp sensing when programmed with loop 3. The low temp zone should be set to zone type 8, 19, or custom. The Detector will generate a low temperature warning when the smoke detector's ambient temperature falls below 41°F (5°C). The thermistor is sampled every 10 seconds. If the ambient temperature falls below the low temperature threshold, the low temperature trouble will be transmitted with the next supervisory transmission. This means the panel will register the trouble anywhere from 70 to 90 minutes after the device is in the low temp state. It is piggy backing on the supervisory transmissions which are sent every 70 to 90 minutes.
The 5808w3 will remain in the troubled state until the ambient temperature rises above the low temperature trouble reset point, which includes a 4°C hysteresis. In a Low Temp condition the green LED will turn off while the red LED will blink once every 10 seconds if the detector is not in maintenance, low battery, or alarm. During a low temperature condition, the zone mapped to loop 3 will trip.
