HARDWIRE
INSTALLATION
The alarm base plate is designed to be
permanently mounted, using it’s own built-
in terminal block to connect it to the mains.
The base plate can be screwed directly to
the ceiling.
WARNING:
Wiring should be installed
by a qualified electrician in accordance
with BS7671. We advise you to follow the
new harmonized cable colour coding as
specified in BS7671.
IMPORTANT:
The circuit used to power
the alarm must be a 24 hour voltage circuit
that cannot be turned off by a switch.
BS 5839: Part 6 states that: For mains
powered alarms, each with an integral
standby supply (Grade D), the mains
electricity supply should take the form
of either a) an independent circuit at the
dwelling’s main circuit 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 electricity
supply to the alarms); or b) a separately
electrically protected, regularly used local
lighting circuit.
• Ensure a permanent connection to the
fixed wiring of the building is made in a
suitable junction box.
• Remove the terminal block cover.
• If trunking is required, snap the break-
out tab away from the base plate prior
to connection.
• The wiring must be connected to the
terminal block as follows:
Live (L)
- Connect to the Live in the house
wiring.
Neutral (N)
- Connect to the Neutral in the
house wiring.
Interconnect (I)
- If desired, join the
Interconnect wire between the alarms.
Use the
terminal to safely terminate
any copper Earth or green / yellow cable.
Neutral (N)
Interconnect (I)
Live (L)

WARNING:
Mixing the Live and Neutral
connections when interconnecting alarms
will damage all the alarms. DO NOT use the
Earth wire for the interconnect connection.
