DUAL PATH - IP & CELLULAR ALARM TRANSMISSIONS: The Cellular BAT replaces outdated conventional phone lines to provide high-speed dual path of IP Internet and Cellular alarm transmission. Alarm transmissions are made using Contact ID format, and this format can be sent to your Central Station via the PSTN to your alarm receiver or can be transmitted directly by IP. Alarm signals such as open/close, trouble, supervisory, latch-key, and monitoring of special devices, can be routed directly to your Central Station or to the customer. Transmissions such as open/close signals can be filtered to the Central Station reducing costs on monitoring fees.
