3. If the PCB version of the IRIS Dialler has been selected, use the self adhesive
stand-off feet fitted to the board to mount the Dialler where required.
4. Connect the 2-wire analogue line interface on the alarm dialler to the DIAL
input connector on the Dialler using the cable provided (Grey). This cable is
terminated at both ends with an RJ11 plug and if the dialler has a connector
block rather than an RJ11 socket, the cable can be cut and stripped. The two
centre cores should be used and the polarity of the connection is not
important.
5. The Dialler has the facility to monitor the connection to the alarm dialler so
that it can detect disconnection and report this to the ARC. If this facility is
required, connect an 18K ohm sense resistor across the 2-wire analogue
interface on the alarm dialler.
Note – for this feature to work correctly it is essential that this resistor is
connected at the alarm dialler end of the cable, not the Dialler end.
The ARC must also enable this facility on this Dialler.
6. Use the Ethernet cable provided (Cream) to connect the ETH interface on the
IRIS Dialler to the local router, hub, switch etc that gives access to the IP
network. The cable provided is terminated at both ends with an RJ45 plug that
is the standard interface used for Ethernet connections on most equipment.
Make sure this cable run is protected from tampering.
Note - it is essential that the Cream cable is used rather than the black
(ISDN) cable.
7. Connect the IRIS Dialler to the power source (normally the 12V battery
backed supply in the alarm panel) using the cable provided (white stripe is
negative). The polarity of connections is important for correct operation,
although the Dialler is protected against damage from the application of a
reversed polarity power supply.
8. When the power is connected correctly several LEDs on the Dialler come on
or start flashing.
4.3 Checking Network Connection
1. A short while after applying power (typically about 10s) the Ethernet interface
to the IP network connection can be checked.
2. If this interface is running correctly the ETH LED will be on steady (it may
flicker from time to time indicating data flow).
