Does the BM service jumper remove power, or just hold the module in reset?
For Combination Fire and Burglary systems, when the shunt is placed on the two left pins ("ON") of this three-pin jumper, the system enters a special mode named "Burg Service Mode" where the system suspends processing Burglary (non-Fire) alarm functions to permit the Burglary part of the system to be serviced (changed) while allowing the Fire system to continue to function as intended. When servicing the Burglary system, we recommend entering Burg Service Mode before removing power to avoid the various troubles (such as a Burg keypad trouble) that will occur. When Burg Service Mode is on, an LED located just below the jumper will light. A Burg Service Mode jumper is also located on the control panel motherboard that is in parallel with the JP2 jumper on the GEMC-BM/PS; either jumper can be used to initiate Burg Service Mode.
