For an early warning in the event of a fire, install this smoke alarm on every floor in your building and in
escape routes, hallways and enclosed rooms to make sure you are protected against fire. Heat detectors
can be installed in kitchens and other areas where smoke alarms are not suitable (if these rooms are not
going to be used as escape routes).
The i series has been specially developed as a high-end, sophisticated product range. An integrated
microprocessor and the extra yellow diagnosis LED allow potential faults to be minimised during regular
maintenance, which means unscheduled servicing can be avoided.
The Ei650C and Ei650iC models can be wire-linked or interlinked wirelessly to form a network, ensuring
the alarm can be heard throughout the building in an emergency. Wireless interlinking requires special
radio models (Ei650M/Ei600MRF). The modules must be purchased separately. The Ei650W and Ei650iW
models can only be interlinked using radio modules.
The Ei650 and Ei650i models are stand-alone smoke alarms that cannot be interlinked using wires or
wirelessly (see table).

2.1 How smoke alarms and heat detectors work
Before a smoke alarm goes off, a sufficient amount of smoke must have entered the
smoke chamber. The smoke alarm should be located less than 7.5 m from the source of
the fire in order to respond quickly. The devices must be installed in locations where
they can be heard throughout the building, so that all inhabitants can wake up and
get out quickly in an emergency. A single smoke alarm can offer limited protection if
it is installed properly, but two or more alarms (preferably interlinked) are needed in
most houses to ensure that a warning is given quickly enough. For optimum protection,
a smoke alarm should be installed in every room in which a fire could break out (except
the kitchen and bathroom).
The first smoke alarm to be installed should be placed between the bedroom and the
most likely source of a fire (for example, the living room). It should be located no more
than 7.5 m from the door of a room in which a fire could break out and block the
escape route.
Heat detectors sound when the temperature on the heat detector reaches 58 °C.
They are recommended for use in kitchens, garages, boiler rooms and other areas in
which there is often a large amount of steam or dust. Smoke alarms cannot be installed
in these locations without the risk of repeated false alarms. A heat detector should only
be used in rooms that adjoin escape routes in which smoke alarms are installed.

2.2 Location
First check what legal requirements there are in your federal state for installing smoke
alarms. Please refer to local building regulations for the exact requirements*. Fire
prevention experts recommend that smoke alarms should be installed at least in every
bedroom and every child’s room, as well as in the escape routes for these rooms (except
in unsuitable rooms such as the kitchen and bathroom).
Multi-storey homes
If there is more than one storey in your home (see Figure 1), at least one alarm should
be installed on every floor. Preferably, the alarms should be interlinked (if this function
is available on your device) so that the alarm sounds throughout the building. Radio
modules, which are easy to install, are ideal for this, as the alarms can be interlinked by
radio – no wires are needed.
For even better protection, you should install heat detectors in kitchens, garages, boiler
rooms, etc. Smoke alarms are not suitable for these rooms.
Heat detectors should be interlinked to the Smoke Alarms.

Minimum protection
■ Smoke alarm on every storey, in every
bedroom and children's room and in
the escape routes for these rooms
Optimum protection
(in addition to the measures already
mentioned):
■ Smoke alarm in every room
(except the kitchen and bathroom)
■ Heat detectors in kitchens,
garages, etc.
■ All devices interlinked
(if this function is available)

Smoke alarm

Single-storey homes
If the building has just one storey (see
Figure 2), place one smoke detector in
every bedroom and every children's room
at least, as well as in the escape routes for
these rooms. Please refer to local building
regulations for the exact requirements*.
In buildings with more than one bedroom,
smoke alarms should also be placed
between the bedrooms and the living room.
Heat detectors should be placed in the
kitchen and garage.
Check if you can hear the alarm
Use activated alarms in the designated locations to check whether the alarm can be
heard when the door is closed in each bedroom – including when there is music playing
or noise from the TV. The TV/audio systems should be set to a normal volume. If you
cannot hear the alarm due to other noise, there is a risk that you would not wake up
in a real emergency. Interlinking alarms using wires or wirelessly (if this function is
available) ensures that an alarm can be heard in the entire building.

2.3 Positioning
Installation on the ceiling
Hot smoke rises and spreads across the ceiling of a room. Because of this, it is
recommended that you choose a central position on the ceiling for installing smoke
alarms. The air “stands still” in corners and does not circulate, therefore smoke alarms
should never be installed in corners. Place the alarm at least 0.5 m away from walls and
corners. Place the alarm at least 0.5 m away from lights or other decorative objects that
could obstruct the smoke's penetration into the smoke alarm. In rooms and hallways less
than 1 m wide, the smoke alarm should be installed in the centre of the ceiling between
the walls (see Figure 3).

Maximum room
height 6 m

Under the applicable standard, a smoke
alarm can monitor an area of up to 60 m²
(see Figure 5).
Information on wall installation
In the following circumstances, smoke
alarms can be installed on a wall, in the
middle third of the longer side of a room
(see Figure 6):
■ Insufficient ceiling strength
■ In hallways ≤ 6 m² (if a high number
of false alarms are likely)
■ In kitchens that are used as
escape routes
The following distances from walls, ceilings
and fixtures must be observed:
0.3 m-0.5 m from the ceiling
1 m below the smoke alarm
0.5 m to the side of the smoke alarm
> 0.5 m > 0.5 m
0.3 to
0.5 m
1 m

Maximum area 60 m²

Sloped ceilings
In rooms with inclined ceilings where
the slope is more than 20° from the
horizontal, pockets of heat can form
in the ceiling apex which can prevent
smoke from entering the smoke alarm.
Therefore, smoke alarms must be installed
at least 0.5 m and at most 1 m from the
ceiling apex in these rooms (see Figure 8).

Hallways
The distance from the front face of the
hallway (hallway = max. 3 m wide) to the
first alarm must not be more than 7.5 m.
An alarm should be installed in corner areas
(cornice joints), junctions and crossings in
hallways. The maximum distance between
two smoke alarms in hallways should be
15 m (see Figure 7).
Max. 15 m

Unsuitable installation locations
Do NOT install smoke alarms in the following areas:
■ Bathrooms, kitchens, shower rooms, garages or other rooms where steam,
condensation or dust could set off the alarm.
■ Do not place smoke alarms in dusty or dirty areas, because dust particles can gather
in the smoke chamber and impair the performance of the alarm. This can also block
the insect screen, which may stop the smoke from entering the smoke chamber.
Avoid areas where there are a lot of insects. Small insects that can get into the smoke
chamber may set off a false alarm.
■ Locations where the normal temperature may rise above 40 °C or drop below 0 °C
(e.g. uninsulated lofts, boiler rooms, directly above ovens or boilers, etc.). Heat or
steam may set off a false alarm.
■ Next to decorative objects, doors, light fittings, window surrounds, etc., which may
obstruct the smoke or heat from entering the alarm.

17
■ On surfaces that are usually warmer or colder than the rest of the room. Due to the
temperature differences, smoke or heat may not reach the alarm.
■ Next to or directly over heating devices or air-conditioners, windows, wall vents, etc.,
which change the direction of air flow.
■ In very high or inconvenient areas (e.g. above staircases) where the alarms are hard
to reach (for testing and silencing purposes).
■ Position the alarm at least 1 m away from dimmable lights and their wiring, as some
dimmers can cause faults.
■ Position wire-linked alarms at least 1.5 m away from fluorescent tubes and lay the
cables at least 1 m away, as the
device may be impaired by electrical “interference”
and/or flickering.

How to install the alarm
1. Choose an installation location in line with the
recommendations in section 2.
2. Remove the mounting plate from the smoke
alarm by turning it anticlockwise (see Fig. 9).
3. Place the mounting plate on the ceiling in the
exact location where you want to install the
alarm. Mark the position of the two screw holes
using a pencil.
4. For wire-linked alarms, use a suitable
two-core cable at the marked positions of
the individual alarms. Make the connections
to the alarm (see section 4.2).
5. Ensure that there are no electric cables in this area of the ceiling and use a 5.0 mm drill bit
to drill a hole in the centre of the marked positions. Insert the plastic dowels into the drill
holes. Screw the mounting plate onto the ceiling. If you decide to install the alarm in
adifferent way, you must ensure the alarm is fixed to the ceiling permanently.
Smoke alarms with a radio module should be installed with the antennae in the same
direction (i.e. largely parallel). To do so, choose part of the building – e.g. the front wall of
the house – and then install the mounting plates so that they all face it (see Figure 10).
Turn the device anticlockwise.
If the device does not detach, it
may have been installed with
tamper proofing (see Figure 12c).
