cover it completely, particularly around the edges, with
a dust cover (eg. with the elasticated cover supplied or
a plastic bag), until all cleaning is finished.
Warning: Wiring should only be installed by an Electrician
in accordance with current IEE wiring regulations for
electrical installation. The installation must also be in
accordance with the control panel instructions and the
instructions in this leaflet.
Warning: The mains circuit used to power the control panel
must be a 24 hour voltage circuit and be wired on a
separate circuit (one with no other lights or applilances) to
ensure maximum reliability of the supply.
Warning: The Alarms must be connected to a panel that
supplies a permanent voltage that cannot be switched off.
Warning: For safety reasons the voltage supply from the
control panel must not be greater than 30V (peak or d.c.)
and must be either independent of the supply mains or
isolated from it by double or reinforced insulations.
Warning: If the control panel is not provided with an
ALL-POLE MAINS SWITCH (with a contact specification of
at least 3mm in each pole), then the electrical installation of
the building shall incorporate an ALL-POLE MAINS
SWITCH, (with a contact separation of at least 3mm in each
pole).
Installation
Select a location complying with the above advice.
1. Remove the mounting plate from the Smoke/Heat Alarm
by releasing the tamper-proof catch with a small screwdriver
as shown in figure 1a and sliding the alarm from the plate.
2. Lift the foam flap covering the circuit on the mounting
plate. If necessary move the jumpers on S1 and/or S2 (see
figure 7) by carefully lifting them and placing them over the
required pins.
3. If surface wiring the unit remove the required breakaways.

Low voltage signal cable is satisfactory (e.g. wire 0.22mm
)
provided the resistance between the units and the panel is
less than 20 ohms.
All wiring must comply with local codes. Connect the wires
to the terminals as shown in the wiring diagram (figure 6).
The gasket flap can be tucked behind the terminals while
this is being done. Place gasket flap back over circuit board
and terminals.
4. Carefully align the mounting plate and screw into place.
With recessed wiring, ensure the rear gasket seals around
the edge of the hole in the ceiling. This is to prevent air
draughts affecting the smoke / heat entering the alarm. If
the orifice is too large it should be sealed with silicone
rubber or equivalent.
Check the battery is connected in the back of the alarm.
Carefully line up the unit on the base and slide on.
