WARNING: Mains operated Alarms should be installed
and interconnected by a qualified electrician in accordance
with the Regulations for Electrical Installations published
by the Institution of Electrical Engineers (BS7671).
Failure to install this Alarm correctly may expose the
user to shock or fire hazards.
WARNING: The Alarm must be continuously powered
24 hours a day so it is important that it is not on a circuit
that can be turned off by a switch.
Note: BS 5839-6: 2013 gives the folowing recommendations
regarding the mains supply to be used in a Grade D system (The
Ei141RC, Ei146RC Smoke Alarms and Ei144RC Heat Alarms can
be used in a Grade D system). The power supply for the Alarms
should be derived from the public electricity supply to the dwelling.
The mains supply to the Alarms should take the form of either:
(a) an independent circuit at the dwelling's main distribution
board, in which case no other electrical equipment should be
connected to this circuit (other than a dedicated monitoring
device installed to indicate failure of the mains supply to the
Alarms); or
(b) a separately electrically protected, regularly used local lighting
circuit.
Alarms should be connected on a single final circuit, unless the
means of interconnection is by radio signals (e.g. RadioLINK).
(See BS 5839-6: 2013 for further information)
Note: The Ei168RC RadioLINK Base can be used to eliminate
interconnect wiring, make system extensions and provide simple
and cost effective compliance with BS 5839-6: 2013.
Mounting & Wiring Alarms
1. Select a location complying with the advice in the
(Positioning Alarms section).
2. Disconnect the AC mains supply from the circuit that
is going to be used.
3. Lift off the wiring cover as shown in Figure 3.
The house wiring must be connected to the terminal block
on the mounting plate as follows:
L: Live - connect to the house wires coloured brown or
marked L.
N: Neutral - connect to the house wires coloured blue
or marked N.

Figure 3
See page 20 for information on interconnection.
Note: Wiring must be installed in compliance with local
regulations.
Warning: Mixing the Live and Neutral connections
when interconnecting alarms will 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.
