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 ZXa/
ZX2e/ZXe/ZX5e 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.
• Easy plug-in type connection
• RS232 and RS485 options
• Hi-485 High-integrity option for critical applications
• Compatible with ZX series intelligent multi protocol fire alarm control panels
• Class-A or Class-B networking capability
• Peripheral bus for remote I/O devices (RS485)
• Leased line modem link (RS232)
• Third-party graphic front-end interfacing
