Essential Info

Having a security system can really add to your peace of mind. But it's no good to you at all if you are away and don't know the system has been triggered. This auto-dialer can call up to 8 numbers to report trouble, and can be programmed with a different voice message for each alarm channel. Besides calling for help, it can also remotely arm or disarm alarm zones with phone commands, and will notify you of the status of, and can control, 4 relay circuits. Add a 24-hour backup battery in case your power goes out.
