Back tamper/Lid tamper
. In the i-on160EX, i-on50EX i-on40 and i-on16 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.
In the i-on16 and i-on30EX the lid tamper is a switch mounted on the main
PCB.
Printed Circuit Board
All of the control unit functions and connectors are provided by a single PCB. In
the i-on160EX a plastic PCB carrier holds the PCB within the case.
Bus Connections
30
50 160.
The i-on EX range of control units provide 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 the relevant
Installation Guide
for details of
bus configuration, maximum bus length and cabling type.
Zone Connections
The control unit itself provides the following connections for wired zones:
Control Unit CC Zones
FSL Zones

These zones can be either all Closed Circuit (CC) or all Fully Supervised Loop
(FSL). The Installer can select the zone wiring type during initial
commissioning, or at any time after. Note that the Installer can make the
wiring type of expanders either CC or FSL, independent of the wiring type of
the zones on an i-onEX control unit. Note that there are no wired zones on the
i-on16 control unit.
Output Connections
Transistor Outputs
The control unit provides connectors for programmable transistor outputs
which can be used to control external equipment. The outputs are normally
switched negative, from 12V to 0V on activation. In this mode each output can
sink up to 500mA from a dc source.
The installer can program these outputs to be switched positive (from 0V to
12V on activation). In this mode the outputs can deliver up to 500mA to an
external load.
See page 8 for the number of transistor outputs available on each control unit.
