ZP3AB-MIP8 Input board
See Figure 50. The ZP3AB-MIP8 Input Board is a programmable input board with 8 separate
inputs. It is designed for connection to normally open, voltage-free contacts (key switches, relays,
etc), the closing of which provides an input signal to the panel. This signal can be programmed to
operate control outputs or sounders, disable zones or devices, change sensor 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 "silent" control function. The input circuit field wiring is monitored for open
circuit.
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 ZP3panel 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 pre-programmed System Bus
section.

Each board is fitted with a Dipswitch, which is set to an address between 32 and 127. This
determines the address of each input, as specified under
User bus address
on page 86.
The inputs are wired in 2-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 2200-ohm, 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.
Note:
If externally supplied, do not common the power supplies, i.e. do not connect the 0V of the internal and
external power supplies together.
