Quick Installation and
Maintenance Guide

6.1 Cable harness attachment
Connect the cable harness to the terminal, by lining
up the connector, matching the colour of the wires
to the label, and pressing firmly in.
6.2 Mounting
The terminal is intended to be mounted within the
existing tamper protected alarm panel enclosure
which means that the interfaces between the terminal
and the alarm panel do not need to be separately pro-
tected against tamper. Identify a location within the
enclosure from which the interface cables provided
with the terminal will reach their required destination
on the panel. The position of the cellular antenna
must also be taken into account, and this is best
located externally to the enclosure.
Fix the terminal into the position chosen using either
the Velcro pads, adhesive mounting pad, cable tie
provided, or some combination of these.
6.3 Connecting cellular
Connect the antenna to the terminal and locate
the antenna in a place away from metal surfaces or
obstructions, and where a good signal strength is
expected to be available. Do not fix the antenna
until after the terminal has been powered up and the
cellular signal strength can be checked (see section
‘Connecting Power’ below).
6. INSTALLATION
6.4 Connecting to the alarm panel
Dial capture
If the dial capture interface (PSTN emulation) is to
be used, connect this to the existing PSTN dialer in-
terface of the alarm panel. Polarity is not important.
Pin inputs
If pin inputs are to be used, connect these to the
appropriate outputs from the panel. By default these
inputs are disabled, and if used should be configured
so that in the alarm condition they are open circuit.
Relay Outputs
If signaling back to the panel is required, connect
either Relay A and/or B as required to the alarm
panel inputs. The relay contacts are voltage free, so
wire accordingly. Relay outputs can be used to signal
various fault reporting states.
By default, Relay A is set to ‘General Fault’, and any
fault condition will therefore be reported by this
relay, such as loss of comms or connection to the
ARC. This does not require any further configura-
tion.
Serial
If a serial interface is to be used, connect RX and
TX to the serial interface from the panel. By default
this interface is set to 9600bps using the
IRIS API protocol.
