,
SUB760, Power supply supervision module,
One of the following class D audio amplifiers:
• SUB864, 20W amplifier
• SUB865, 60W amplifier or
• SUB866 , 120W amplifier or
• SUB867, 250W amplifier (special option),
Other options can be used, depending on system requirements and available space in the standard
metal enclosure:

OWS 4 Zone Splitter Board fits 4580 brackets
• PA-1 Brooks Remote Paging Desktop Microphone with BGM / PA enable / disable control
SUB862 is replaced with SUB999 which is about 30% smaller. Its circuitry and features remain unchanged.
The board profile was replicated from 458x series of expansion boards that are used in the Addressable
CIEs so that the mounting brackets CB575 & CB574 can be used for mounting up to 4 boards, see
Figure 6.
3.2 Monitored Inputs and Outputs
The Brooks OWS provides inputs and outputs as listed in Table 2 below, each input or output is
supervised for open or short circuit faults. The inputs or outputs require an End Of Line (EOL) resistor,
47K, 1%, metal film, 1/2W.
