What is the Casil CA631 SLA Battery used for?
A GSM (Global System for Mobile communication) is a cellular device that is mounted to an alarm panel, like a Honeywell Control Panel, in order to provide a backup wireless line of communication with a user's central monitoring station. Cellular communicators are rapidly growing in popularity because they are more reliable than internet communicators, like the 7847i, and they act as a communication safety net should a home telephone line become damage or cut. Even in a power outage situation, a GSM communicator can send wireless alarm signals over a cellular network.
