Each output is allocated a unique address, and programmed to operate from
selected inputs using the I/O-mapping function built into the panel. The
ZP3AB-MA8 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.

Supplied from separate 24 VDC power
supply unit. [1]
[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] Each board is fitted with a DIP switch, which is set to an address between 000 and 127. This
determines the address of each output, as specified in “System address list” on page 97.
Each output provides 24 VDC in alarm, and can drive a maximum circuit load of
1 A. If outputs are used to switch inductive loads, they should be protected with a
flyback diode.
The load is provided from the 24 VDC supply connected to the power input
terminals. If connected to the ZP3 panel auxiliary power supply terminals, the
load is supplied from the built-in ZP3 power supply. If connected to an external
24 VDC power supply, the external supply supplies the load.
See Figure 49 on page 66. The ZP3AB-OP24 Transistor Output Board is a
programmable output board with 24 separate outputs, designed to drive low-
power functions, such as LEDs or control relays. This board is suitable for driving
remote mimic panels. The outputs are open-collector transistor outputs, which
switch negative (0 volts) when activated. Connect the opposite side of the output
