Power Outputs - Circuit Protection

Three self-resetting circuit breakers protect the control panel from short circuits on the
continuous and programmable power outputs. If the control panel is programmed for power
supervision and a short circuit occurs on one of the power outputs, the control panel sends a
BATTERY LOW or BATTERY MISSING for Bosch Security Systems Modem IIIa
Format, or a Battery Missing/Dead (311) or Low System Battery (302) for Contact ID Format.
One self-resetting circuit breaker protects:
–
–
NOTICE!
A short circuit on one terminal disrupts power to the other terminal.
Another self-resetting circuit breaker protects:
–
–
–
NOTICE!
A short circuit on one of the terminals disrupts power to the other two terminals.
The third self-resetting circuit breaker protects Terminal 32: Power +.
NOTICE!
UL requires any device powered from a power output to be supervised.
NOTICE!
UL requires that power outputs are not shared between fire and non-fire devices unless all
devices are in conduit within 20 ft and are in the same room.
