Sensaphone FGD-0100 Remote Temperature Sensor, 2.8K

Monitor air temperature

Designed to monitor air temperature in a clean, indoor, environment. Sensing range depends on product. Does not come with wire.

When an alarm is detected, the Sensaphone can notify selected people by making voice phone calls. It will continue to make phone calls until someone responds to the call. The voice messages can be custom recorded, so you get to describe each alarm message that it speaks in your own voice. The phone interface includes a line seize feature so that extension phones are automatically disconnected when it needs to make an alarm phone call.

A built-in output relay is provided to switch an external device either automatically, or manually. You can use it to have a local light or siren trip when an alarm occurs, or even to set off a local alarm when the phone line is cut or unplugged. You can even use it to control a dual setback thermostat to change the temperature remotely. Also includes nonvolatile memory and a 24-hour battery backup with user installed batteries.
