Product Description
Ordering Key
Smoke detector G8910 2217
allows early detection of
smoke-developing smoulder-
ing and flaming fires. The
smoke detector operates on
the proven principle of light
scattering. The sensing
chamber contains a light
source and a light sensor
positioned so that light only
hits the sensor when airborne
particles enter the chamber
(Tyndall effect), thereby gen-
erating the electric signal.
This design eliminates the
need for a radioactive source.
G8910 2217 only requires to
be connected to Dupline. All
signals, ie smoke alarm, sta-
tus signal - indicating correct
connection between the
smoke detector and the built-
in Dupline circuit board - as
well as signal indication of
successful self-testing are
transmitted via the Dupline
bus.
G89102217 features LED
indication of alarm and oper-
ational state of the detector. A
test button allows manual
testing of the alarm function,
while simultaneously an alarm
is transmitted via the Dupline
bus.

Wiring Layout
Position of the
PCB (A) in G8910
2217: The Dupline
signal wire is led
through the hold-
ing device (E) and
fastened at the
screw terminals
(B). Subsequently,
the PCB is fitted in
the G8910 2217
so that the con-
tacts (C) lead into
the holes.
Notes on Applications
To achieve minimum protec-
tion, a G8910 2217 should be
installed in each sleeping area
and/or on each floor. A smoke
detector installed in each
room will ensure higher pro-
tection (except in the kitchen
and bathroom, where steam
may cause false alarms).
The following guidelines must
be observed when using
G8910 2217:
The floor area and floor-to-
ceiling height in rooms must
not exceed 60 m
2
and 6 m
respectively.
The width and length of hall-
ways and narrow corridors
must not exceed 3 m and
15 m respectively.
The smoke detector should
be mounted as close as
possible to the centre of the
room.
A gap of at least 0.5 m from
walls and furniture must be
observed.
The G8910 2217 must NOT
be mounted at the following
locations:
Near to ventilation ducts or
strong draughts.
Directly in the apex of
pitched roofs (a minimum
distance of 30 cm from the
apex must be observed).
In rooms where - under nor-
mal conditions - a lot of
steam, dust or smoke is
present (for example in
workshops, bathrooms and
laundry rooms).
