Introduction

System Overview

i-on160EX is the control unit for a hybrid wired/wirefree alarm system intended

for commercial use. One i-on160EX control unit can operate up to 160 zones

by using expanders communicating over a single bus cable. Different types of

expander allow either wired or wirefree detectors in the same system. The

single bus cable also allows the installer to connect keypads, output modules

or extra power supplies wherever they are needed.

System Design

The i-on160EX is designed to support a wide range of alarm system sizes. The

control unit printed circuit board (pcb) itself provides ten zones and four

outputs. To increase the size of the alarm system the Installer can connect

expanders and keypads to a single “bus” which carries all the data between the

control unit and its peripherals.

The control unit pcb provides connections only for wired zones and outputs.

Expanders provide connections to either extra wired zones and outputs, or

radio detectors and radio outputs. Both wired and radio devices can exist in

the same alarm system.

The Control Unit

Case

A coated steel case houses the control unit’s pcb, power supply and backup

batteries. The case is designed for vertical mounting on a wall, and provides

three fixing points. The case can be butted up to side walls or a ceiling without

blocking the opening or closing of its lid. The case lid is fixed by a single screw,

and can be hung from the case back when open. The back of the case provides

pre-cut holes for cable access, and stands 14mm off from the mounting

surface to allow trunking to pass behind.

As well as the pcb, the case provides room for two 17Ah backup batteries.

Cooper Security provide securing clamps for each battery with the case.

Back tamper/Lid tamper. The back of the case provides a plastic shrouded

slot through which the Installer can fit the combined back tamper/lid tamper

switch. This switch is mounted on a metal blade that slides through the slot

and touches the mounting surface. Once fitted and connected to the pcb,

removing the lid or prising the case from the wall activates the switch.

Printed Circuit Board

All of the control unit functions and connectors are provided by a single pcb. A

plastic pcb carrier holds the pcb within the case.

Bus Connections

The control unit provides connectors for one four-wire bus cable. All keypads,

expanders and other equipment connect to the same bus. The cable can be run

as one single line, or as a three or four armed star branched at the control

unit. See i-on160EX Installation Guide for details of bus configuration,

maximum bus length and cabling type.
