10.2 8-Way Sounder Board
The Sounder Board expands the number of sounders that can be used on an FACP by 8. Each
output is of a solid state design, rated at 24VDC / 750mA and requires a 10K
Ω End of Line (EOL)
resistor regardless of whether or not a sounder is wired to the circuit.
The sounder board is only available in a local version hence can not be mounted remotely from the
FACP.
The sounder board will switch ON the sounders as configured (output off, continuous or pulsed) at
the FACP and supervise the sounders for their open circuit, short circuit & line fault conditions.
Note:
Sounder polarity MUST be observed.
