Warning: Mixing (or leaving unattached) the Live and Neutral connections when interconnecting
Alarms may damage all the Alarms - ensure that the same colour wires are used throughout the
premises for Live, Neutral and Interconnect wires.
We strongly recommend that you check for the following before connecting the Alarm:
• check for Live and Neutral using a two probe tester.
• check for Live using a neon tester.
• check that the Interconnect wire is NOT connected to Live, Neutral or Earth. Do not use an Earth
wire for the Interconnect line.
Note: The Alarm does not need to be earthed. However the terminal marked is provided for the
convenience of the installer so that any copper Earth wire or cable coloured green and yellow, can
be safely terminated.
To interconnect Alarms connect all the IC terminals together as shown in Figure 9 (see
Interconnecting Alarms section).
