The Modbus interface unit connects to the RS-485
peripheral bus of the ZX series fire alarm control panels
and allows panel interrogation by a Modbus control
system. Information on the states of panel outputs,
peripherals, detectors and the general operating
condition of the panel can be requested.
The unit consists of a circuit card mounted on a steel
plate within a polycarbonate IP67 rated enclosure, as
shown above. Pre-pressed knock-outs on the box sides
allow cable entry glands to be fitted for power and
communication line wiring.
A DC supply in the range of 18-28 Vdc, typically 24 Vdc,
rated at 150 mA, is required to power the interface, An
on board switch mode power supply isolates this input
from all communication circuitry. An adequate DC
supply can be obtained from the fire control panels
auxiliary 24 Vdc output (see fire control panel manual).
An earth reference should be connected to the Modbus
Interface Platforms Earth termination point from the
supply earth (i.e. fire control panel entry gland).
For a complete listing of the commands supported
please refer to the installation guidelines and
commissioning instructions, document EXP-057.
