When you need to monitor additional conditions, or need to notify more people, the 800 is the best choice. It has all of the same features as the 400, but instead of four external inputs, it is equipped with eight. And instead of being able to notify four people, it can notify eight using the same custom voice phone call technology. And like the 400, one of the external inputs comes with a local temperature sensor installed.

The 800 has a built-in ability to monitor for power failures and to listen to the sound of a smoke detector. There are also eight external inputs that can be connected to a variety of sensors to monitor temperature, water on the floor, humidity, and much more. One of the eight external inputs already comes with a temperature sensor for monitoring temperature where the 800 is installed.

When an alarm is detected, the Sensaphone 800 can notify up to eight 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.
