About the Accessory Board Connector
The AlarmSaf Accessory Board Connector (ABC) allows plug-in system expansion using
compatible AlarmSaf accessory boards. The ABC is capable of carrying both primary and
secondary voltages (if applicable), DC common, fault status, and fire alarm interface status.
Products can be daisy-chained together, maintaining voltage, fault, FAI, and DC common
continuity throughout the chain.
NOTE: There are 6-pin and 8-pin versions of the ABC. The 6-pin version carries ONLY a single
voltage while the 8-pin version can carry two independent voltages for dual voltage systems.
6-Pin and 8-Pin Accessory Board Connectors
CAUTION: The ABC-01 and ABC-02 cables are used on the older Beacon Power supply boards
(PCB#: 38-118 REV A02 or earlier) that have a 6-pin ABC connector.
DO NOT USE these
cables on newer Beacon Power supply boards (PCB # 38-118 REV A03A or later) that have an
8-pin ABC connector or damage to the system could occur.
