400 offers an easy, inexpensive way to monitor your remote
facility, cabin or vacation home. Installed in a clean indoor environment, it has built-in monitoring for power failures, temperature, and sound monitoring of audible alarms. Four external inputs on the back can be connected to various external sensors to monitor temperature, water on the fl oor, humidity, intrusion and more.
When an alarm is detected, the 400 can notify four people
by making voice phone calls. It will continue to make phone
calls until someone responds to the call. The 400 also includes nonvolatile memory and a 24-hour battery backup
with user-installed batteries.
