Connecting to an External Alarm

The Excalibur Multirate DAP provides a 10-pin jack labeled EXT ALM for connecting

to an external alarm device (such as a burglar alarm or smoke detector). This enables an

alarm device at a remote site to transmit an alarm through the secondary channel back to

the central site.
