i-on RangePage 1IntroductionSystem DesignThe i-on range of control units for hybrid wired/wirefree alarm systems are intended for,domestic, commercial or industrial use. The range is designed to support a wide spread ofalarm system sizes. To increase the size of the alarm system the i-onEX control unitsallow the Installer to connect expanders and keypads to a single “data bus” which carriesall the data between the control unit and its peripherals.The control unit PCB provides connections for wired zones and a number of outputs. TheExpanders provide connections to either extra wired zones and outputs, or radio detectorsand radio outputs. Both wired and radio devices can exist in the same alarm system. Thesingle bus cable also allows the installer to connect keypads, output modules or extrapower supplies wherever they are needed.The Control UnitCaseAll i-on control units are housed in an individual case that provides space for the controlunit’s PCB, power supply and one or more backup batteries. The cases are designed forvertical mounting on a wall, and provide three or more fixing points.The i-on160EX, i-on50EX and i-on30EXL cases are made of coated steel and can bebutted up to side walls or a ceiling without blocking the opening or closing of its lid. Thecase lid is fixed by a single screw, and can be hung from the case back when open. Theback of the case provides pre-cut holes for cable access, and stands off from the mountingsurface to allow cables to pass behind.The i-on30EX case is also made of coated steel, and has an “all-over” lid fixed on by a twoscrews.The i-on16 and i-on40 cases are made from ABS plastic.Battery BackupThe i-on160EX case provides space for two 17Ah backup batteries. Each battery has itsown connector on the control unit PCB, and is charged by the control unit while mainspower is present.It is possible to run the system with a single backup battery (although the resulting standbytime may not meet the Grade 2 or Grade 3 requirements). If you chose to use a singlebattery, then you should connect the battery to connector “BATT1” and program thecontrol unit to suppress alerts that Battery 2 is missing, see page 104.The i-on50EX and i-on30EXL provide space and a connector for one 17Ah battery.The i-on16, i-on30EX and i-on40 provide space and connectors for one 7Ah battery.Back tamper/Lid tamper. In the i-on160EX, i-on50EX i-on40 and i-on16 the back of thecase provides a plastic shrouded slot through which the Installer can fit the combined backtamper/lid tamper switch. This switch is mounted on a metal blade that slides through theslot and touches the mounting surface. Once fitted and connected to the PCB, removingthe lid or prising the case from the wall activates the switch.In the i-on16 and i-on30EX the lid tamper is a switch mounted on the main PCB.
