ZXSe Communication Modules

Product Overview
The serial communication modules are plug-in expansion modules
for use in the ZX series intelligent multi-protocol fire alarm control
panels. These optional modules add optically isolated communication
ports to the ZX series control panels to allow serial communications
for networking and peripherals. Two types of serial communication
protocols are available with the ZX series control panels:-
• RS485 Communication protocol
• RS232 Communication protocol
The RS485 communication module supports two-wire RS485 multi-
drop transmission between networked ZX2Se/ZXSe/ZX5Se control
panels, between ZX series control panels and repeaters or between ZX
series control panels and serial peripheral devices. Using a shielded
twistedpair cable with a cross sectional area of minimum 0.5 mm2
(24 AWG), the RS485 module will support cable/bus lengths of 1,200
meters (3937 ft) per channel.

When used to drive a peripheral bus the RS485 module can support
remote I/O devices such as:
• Active and passive repeaters
• External printers
• 4-way programmable relay and sounder cards
• 8-way input cards
• 40-way mimic driver cards
• Modbus and pager interface modules
The RS485 communication module can also be used in conjunction with
the Hi-485 conversion module for systems requiring a “High Integrity”
loop for network communications. The Hi-485 nodes are able to detect
and isolate transmission line faults such as short and open circuits on
the network wiring.

The Hi-485 modules also act as signal repeaters/boosters, which enable

“High Integrity” loops of up to 12 km (39,370 ft) to be constructed.

The RS232 communication module supports a single point-to-point

communication between ZX series panels. The panels can also be
installed remotely if a suitable modem and leased or private line are used.

• Class-A or Class-B networking interfacing
• Easy plug-in type connection capability
• RS232 and RS485 options • Peripheral bus for remote I/O devices
(RS485)
ZXSe Communication Modules
The RS232 module also supports a single point-to-point transmission
between a ZX2Se/ZX5Se control panel and graphic front end.

When used in an ZX5e control panel, the RS232 module can also be
used as a communication interface to the pager interface. This option is
not available with a ZX1Se/ZX2e panel.

The AUTO-LEARN facility provided in the ZX series control panels saves

considerable time and effort when installing new plug-in modules and
peripheral devices or when changing system configuration. It allows the
system to learn itself what modules and peripheral devices have been
installed on the panel.
