sensitivities, or carry out other functions. The activation of these inputs is not
displayed as an alarm by the panel, but rather treated as a

control function.
The input circuit field wiring is monitored for open circuit faults.
Each input is allocated a unique address, and programmed to operate selected
outputs or functions using the I/O-mapping function built into the panel. The
ZP3AB-MIP8 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. It does not operate on the preprogrammed System Bus section.

[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 32 and 127. This
determines the address of each input, as specified in “User bus addresses” on page 100.
The inputs are wired in two-wire Class B single direction format. If connected to
more than one contact, they must be daisy-chained from point-to-point, without
spurs. Circuits must be terminated with a 2.2 k
ȍ
, 0.5 W end-of-line resistor at the
end of the circuit.
The board can be connected to the ZP3 panel auxiliary power supply terminals,
or to an external 24 VDC power supply.
