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
