Alarm Connections

The Total Access 1224 provides an Type SP15 connector (see
alarm inputs and three alarm outputs (Major, Minor, and Critical). If load shedding is active
then the Critical alarm output will be active. Alarm inputs are activated by shorting A and B
contacts (closing an externally connected relay). The outputs provide both normally open and
normally closed pins (through internal relay contacts) for proper operation with a variety of
alarm panels. Each alarm event generates an autonomous TL1 message that is transmitted
via the in-band management channel to a monitoring device.
A cable with a Type SP15 male connector on one end and a stub at the other end is available
(P/N 1196DB901L1) for wire-wrap connections to an alarm panel.
