4 Installation – Alarm Transmission and Polling over IP
4.1 Preparation Prior to Installation
1. Check that the ARC to which connection is to be made supports Chiron’s IRIS
Alarm over IP system.
2. The IP address of the Polling Engine/Receiver at the ARC is required – this
will be a twelve digit number. Note – IP addresses are often provided as four
numbers separated by the “.” character, e.g. 192.168.3.34. This will need to
be converted to a twelve digit equivalent by adding leading zeroes to each
number to make them up to three digits each, and then removing the “.”s. The
address above becomes 192168003034.
3. The account (“chip”) number is loaded into the alarm dialler – this is the same
as required for any standard dialler installation.
4. The IRIS Dialler should be set to factory defaults. If it is believed that the
Dialler has been used before on another site and retains that configuration, it
should be set to defaults. The way to do this is describer in the Local
Configuration sections of the User Guide.
5. The IRIS Dialler has an Ethernet interface for IP network connection that uses
Automatic IP addressing (sometimes referred to as DHCP). If Fixed IP
addressing is required this can be set up on the IRIS Dialler as described in
the Local Configuration sections of this User Guide.
4.2 Physical Installation
1. It is recommended that the IRIS Dialler is located within the same enclosure
as the alarm dialler so that it can be powered from the battery backed power
supply, protected by the tamper switch and wired directly to the alarm dialler
without any external cabling.
2. Make allowances for the external wiring which will be required, i.e. IP network
connection via the Ethernet cable. Make sure external cable runs are
protected from tampering.
3. If the PCB version of the IRIS Dialler has been selected, use the Velcro fixing
strips 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.
