The GE Security MPI-267 is “the right connection” for almost any 12 VDC control, power supply, or other such powered device which uses a transformer and 12 VDC battery. The MPI-267 is a compact circuit board which mounts with double sided tape. It provides a convenient way of shutting off power, both A.C. and D.C. to a control, power supply, or other similar device. An on-board relay is an optional function which disconnects a backup battery when A.C. fails and the battery voltage drops to below 7.5 VDC. The benefits of this function help to eliminate deep discharged batteries, possible cell polarity reversal when the battery is allowed to reach an extremely low voltage condition, and ultimately fewer service calls.
