(d) In exhaust streams from gas engines, vents, flues or chimneys
(e) Do not place in close proximity to an automobile exhaust pipe;
this will damage the detector
INSTALLING YOUR DETECTOR
The Carbon Monoxide Detector is easy to install to protect you and
your family in your home, cottage, cabin and office.
The product can be installed flush mounted set into a wall/partition.
You will need the following tools to install the unit:
Drill with a 6mm bit
Phillips screwdrivers
The product is designed with the cables emerging from the bottom
of the unit.
Flush mounting
In order to flush mount the unit a suitable hole will needs to be cut
in the wall. This will need to be 150mm wide by 90mm high and a
minimum of 40mm deep. The power supply cabling and
connections for the Remote LED and relay (if used) will need to
come from behind or inside the wall. This will normally be via
conduit in solid wall or from inside the outer skin of a partition wall.
Once mounted in the hole in the wall, the unit can be secured to the
wall using the two screws provided (and if needed the raw plugs)
through the two holes either side of the base.
Figure 1 – Flush Mounting
Before connecting power ensure you have selected the correct
connection for either mains or DC installation, checking the label on
the product.
Feed the cables for the power (and, if used, the relay and Remote
LED) up from the underside of the base. The cables are then
secured using the cable clamps provide. The cable clamp can be
reversed to accommodate larger cables as shown.

Mains Powered Connect
CAUTION: ISOLATE THE MAINS BEFORE STARTING WORK
The detector should be wired to the mains supply via an
unswitched fused outlet to BS5733. The fuse should be rated at 3
Amps. The brown or red wire should be connected to the live
terminal shown L below and the blue or black wire should be
connected to the neutral terminal shown N. The earth terminal is
not required.
Figure 3 AC Supply Wiring
DC Powered Connect
The detector should be wired to the 12V or 24V supply with a fuse
rated at 3 Amps. The red wire should be connected to the terminal
shown below with a + (plus) sign and the black wire to the negative
terminal shown with a – (minus). Reversing the connections may
damage the product.
In caravans and motorhomes the detector should be connected to
the battery supply via the main switch. This will ensure operation
when the caravan is occupied. Permanent connection for prolonged
periods may cause a flat battery if the battery remains uncharged

HOW TO USE THE RELAY FACILITY
The relay provides a means of signalling an alarm condition to an
external warning device such as control panel or remote audible
buzzer. It can also be used to shut off a gas valve in the event of a
detected leak. The relay is a single pole changeover type that
allows contacts to be either open or closed when gas is detected.
Relay contacts can be wired in parallel to provide an alarm signal
when any of the units connected detect gas.
For the mains powered versions the relay contact is specified up to
240V @ 6A ac and for DC powered versions its is specified at 24V
@ 6A
