Drilled Hole Mounting; Testing, Maintenance And Servicing - Abus Rwm450 Bedienungsanleitung

(Q) and EN14604:2005/AC:2008 in
addition to 1.1
The additional use of this optional
adhesive produces an
• extremely firm
• and long-lasting joint between the
alarm unit and the fixture and thus
with the installation site.
• The alarm unit cannot now be
removed by pulling it from the
magnetic holder; this means signifi-
cantly greater security against
unauthorised removal, theft etc.
Only use this method of fixing when
you are absolutely certain that the
unit must remain permanently fixed
and that it should not be removed.
Be certain to note that this is a
very strong fixing; the unit can
only be removed with great effort
and possible damage to the
mounting site and to the device.
We accept no liability for any
damage incurred.
Application:
a) Remove the information sticker
and the protective film from the
self-adhesive surface (Fig. 3) of
the magnetic holder.
b) Press the adhesive surface of the
magnetic holder for approx. 10
seconds firmly onto the mounting
surface.
c) Remove the first protective film
from the thin double-sided
adhesive film and press this firmly,
smoothly and flush onto the entire
metal surface of the smoke alarm
unit.
d) Now remove the second protective
film of the thin double-sided adhe-
sive film and place the unit with
gentle pressure onto the pre-moun-
ted magnetic holder.
e) The adhesive bond will reach its
final strength after approx. 72 hours.

2. Drilled Hole Mounting

Application:
a) Using an 8-mm drill bit, drill a
hole at the installation position
(take care not to strike any electric
cables, etc. underneath).
b) Insert the 8-mm wall plug into
the hole.
c) Push the 5-mm countersunk screw
provided through the bottom of
the magnetic holder and into the
hole (Fig. 4).

d) Tighten the screw into the wall
plug so that the screw sits flush
and is fully sunk into the recess
provided for it in the magnetic
holder.
e) Only tighten the screw sufficiently
to prevent the magnetic holder
from deforming or bending.
f) Place the alarm unit on the mag-
netic holder.
g) If required the unit can be
removed
from the magnetic holder by pull-
ing it gently vertically away.

TESTING, MAINTENANCE AND SERVICING

This smoke alarm automatically tests
its functional readiness once every
minute. It automatically adjusts the
sensitivity of its detection optics
according to the prevailing environ-
mental conditions. If the energy
reserves of the smoke alarm are
depleted or the detection optics are
so contaminated that it can no longer
adjust its sensitivity to the condi-
tions, the device indicates this
situation at an early stage so that you
have sufficient time to replace the
smoke alarm with a new unit.
You should ensure that the air inlets
around the sides of the smoke alarm
never become constricted by dust,
dirt, paint or adhesive tape, etc.
To check that the device is fully
functional you should regularly (at
least once per month) test the alarm.
To do this, press the Test and Stop
button (Fig. 1, IV) to trigger a test
alarm (Fig. 5). When you do this,
check that the unit is undamaged
and securely fixed to its mounting
location, and that the air inlet fins
(Fig. 1, II) are completely free of
foreign bodies.
