Warning: Mixing the Live and Neutral connections when interconnecting Alarms may damage all
the Alarms - ensure that the same colours 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).
