address, and programmed to operate from selected inputs using the I/O-mapping
function built into the panel.
The ZP3AB-RL8 board connects to the ZP3 panel control bus. If allocated to the
User Bus section, up to 768 addresses are available. These outputs are freely
programmable. If allocated to the System Bus section, a further 256 addresses
are available, which have preprogrammed functions.

[1] If externally supplied, do not common the power supplies, i.e. do not connect the 0V of the
internal and external power supplies together.
[2] If outputs are used to switch inductive loads, they should be protected with a flyback diode.
[3] Each board is fitted with an eight-segment DIP switch. This switch is set to an address
between 000 and 127. This board address determines the address of each output, and is
specified in “System address list” on page 97.
See Figure 48 on page 65. The ZP3AB-MA8 Monitored Output Board is a
programmable output board with eight separate outputs, designed to drive fire
alarm sounder or control outputs. Outputs monitor the circuit field wiring for open
circuit and short circuit faults, and report to the panel should a fault occur. The
outputs operate on a reverse polarity basis, being set to one polarity for normal
and reversing polarity for alarm. Outputs must be polarized with a polarizing
diode (these are often internally fitted on sounders). The outputs are wired in
two-wire Class B single direction format. They must be daisy-chained from point-
to-point, without spurs. Circuits must be terminated with a 2.2 k
ȍ
end-of-line
resistor at the last device on the circuit.
