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.

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).

3. If the ETH LED is flashing on/off on a .5s/.5s cycle, then the Ethernet

connection has not synchronised. This could be for a number of reasons:

• Cable not connected properly.

• Cable connected to wrong device or port on device (e.g. router).

• Device to which cable connected not switched on.

4. If the ETH LED flashes off briefly every 1s, then this indicates that it is

synchronised but has not been given an IP address. The IRIS Dialler may

need to be set with a Fixed IP address (see Local Configuration sections).

Consult the local Network Manager.
