Checking you can hear the Smoke & Heat Alarms
With the Alarm sounding in its intended location, check you are
able to hear it in each bedroom with the door closed, above the
sound of the radio. The radio should be set to a reasonably loud
conversation level. If you can't hear it over your radio the
chances are that it wouldn't wake a person.
If a Smoke Alarm is too far away for it to wake a person, it is
best to interconnect to another Smoke Alarm or Heat Alarm

near the bedroom, so when one alarm senses fire, all
interconnected alarms respond (see below for further details).
LOCATIONS TO AVOID
Don't place Smoke Alarms in any of the following areas:
• Bathrooms, kitchens, shower rooms, garages or other
rooms where the smoke alarm may be triggered by steam,
condensation, normal smoke or fumes. Keep at least 6
metres (20 feet) away from sources of smoke.
Don't place Heat Alarms in any of the following areas:
• Bathrooms, shower rooms or other room where the unit
may be triggered by steam or condensation.
Don't place Smoke or Heat Alarms in any of the following
areas:
• Places where the normal temperature can exceed 40°C
(104°F) or be below 4°C (39°F) e.g. attics, furnace rooms
etc. directly above ovens or kettles, as the heat/steam
could cause nuisance alarms.
• Near a decorative object, door, light fitting, window
Figures 2 moulding etc., that may prevent smoke or heat from
entering the Alarm.
• Surfaces that are normally warmer or colder than the rest of
the room (for example attic hatches, uninsulated exterior
walls etc). Temperature differences might stop smoke or
heat from reaching the unit.
• Next to or directly above heaters or air conditioning
vents, windows, wall vents etc. that can change the
direction of airflow.
• In very high or awkward areas (eg. over stairwells) where it
may be difficult to reach the alarm (for testing, hushing or
battery replacement).
• Locate away from very dusty or dirty areas as dust build-up
in the chamber can impair performance. It can also block the
insect screen mesh and prevent smoke from entering the
6
4
smoke detector chamber.
• Locate the unit at least 1 metre (3 feet) from dimmer
controlled lights and wiring - some dimmers can cause
interference.
• Locate unit at least 1.5m (5 feet) and route wiring at least 1m
(3 feet) away from fluorescent light fittings as electrical
"noise" and/or flickering may affect the unit.
Dwelling with Recommended
• Do not locate in insect infested areas. Small insects getting
into the smoke detector chamber can cause intermittent
alarms. Insects and contamination on the Heat Alarm sensor
can increase its response time.
KITCHEN
POSITIONING SMOKE/HEATALARMS
The locations must comply with applicable building regulations.
DINING
BEDROOM
Hot smoke rises and spreads out, so a central ceiling position is
the preferred location. The air is "dead" and does not move in
corners, therefore Smoke & Heat Alarms must be mounted
away from corners. Place the unit at least 300mm (12 inches)
from any light fitting or decorative object which might obstruct
smoke / heat entering the Alarm. Keep at least 300mm (12")
away from walls. See figure 4. (Smoke Alarms should be
located directly on the ceiling or up to 570mm below it. Heat
Alarms should be located directly on the ceiling or up to 90mm
below it).
Wall mounting is not recommended for these Alarms.
Sloping Ceiling
In areas with sloping or peaked ceilings install your
Smoke/Heat Alarm 90mm (3 feet) from the highest point
measured horizontally (see figure 5), because "dead air" at the
apex may prevent smoke from reaching the unit.

INTERCONNECTING SMOKE/HEAT
ALARMS
When a fire is sensed the alarm must be given throughout the
house. Up to twenty (20) Smoke Alarms (models EI 180, 181,
185, 186 only) and Heat Alarms (model EI 183, 184 only) can
be interconnected so that when one senses fire all alarm.
Caution: Do not interconnect to any other type of alarm.
The unit initiating the alarm can be identified by the red LED on
the cover flashing every second. Figure 6 shows the
interconnect wiring.

Note: It is only necessary to wire one relay to the control panel.
If any alarm senses fire this relay will change state due to the
signal on the interconnect line.
These Alarms should be interconnected only within the
confines of a single family living unit. If they are interconnected
between different units there may be excessive nuisance
alarms. Everybody may not be aware that they are being tested
or that it is a nuisance alarm caused by cooking etc. When one
unit alarms all relays will switch.

planned to ensure nuisance alarms are not excessive, e.g.
from cooking or weekly testing.
Smoke Alarm Locator Switch (EI 159) should be incorporated
into the system and be readily accessible to all occupants so
that the source of an alarm can be quickly identified. (see
Accessory section).
All Alarms must be cleaned and maintained regularly.
A competent person must be on call to quickly remove any
faulty alarms (i.e. units with red light flashing), which are
causing all alarms to sound.
INSTALLING SMOKE/HEAT ALARMS
The Alarm is designed to be permanently mounted , using it's
own built-in terminal blocks to connect it to the panel. The
mounting plate can be screwed directly to the ceiling after
connecting the wires.
IMPORTANT PRECAUTION: Do not install the actual alarm
itself in new or renovated buildings until all work is
completed (including floor coverings) and the building has
been fully cleaned. The wiring can be installed when
appropriate. (Excessive dust and debris from building
work can contaminate the smoke chamber or heat sensor
and cause problems, it will also invalidate the guarantee).
If it must be installed, 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
Figure 5
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
900mm
must be either independent of the supply mains or isolated from
(3 ft)
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.
2
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.

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 ( EI
181, 184, 186 only).
Carefully line up the unit on the base and slide on.
Press the test/hush button for 10 seconds. The horn should
sound (EI 181, 184, 186 only).
7. Connect the panel power to the alarm circuit. The green light
on the mounting plate should turn on.
Check the operation of the Alarm as outlined in the next
section.
CHECKING AND MOUNTING YOUR
ALARMS
INSPECTION & TESTING PROCEDURE
After installation, after re-occupation following a holiday, and
weekly, check all your Alarms as follows:
Check the green light is illuminated on the mounting plate. This
shows the panel is supplying power.
Press the test button for up to 10 seconds to ensure the
sensor chamber, electronics and sounder are working. A red
light on the cover will flash while horn is sounding. The relay
contacts should change over with the EI185, EI186 relay
contacts when the horn sounds with the EI180, EI181, EI183,
EI184, it contacts within 6 seconds after the horn sounds. The
alarm will stop when the button is released. Pressing the test
button simulates the effect of smoke or heat during a real fire
and is the best way to ensure the Alarm is operating correctly.
WARNING: DO NOT TEST WITH FLAME.
This can set fire to the Alarm and damage the house.
We do not recommend testing with smoke or heat as the results
can be misleading unless special apparatus is used.
Check for any sign of contamination such as cobwebs or dust
and clean the alarm as described below if necessary.
Interconnected alarms
Test the first unit by pressing the button. All the detectors
should alarm within about 5 seconds of the first horn sounding
and the red light on the first unit only will flash once a second.
The relay contacts should change over about 6 seconds after
the horns sound. Check all the other units similarly. (Note:
Ionisation and Heat alarms signal to other interconnected
alarms, about 4 seconds after their own horn sounds. Optical
alarms signal within about a second).
