anti-lock protection
The bell is protected against the "jokers", who block the bell switch-keys in
a position "pushed in" for purpose of producing a continuous reproduction
of the signal. In the case of such treating the KAKADU bell, the signal will
be reproduced only once, and it can be started again only after release
and re-pressing the switch-key.
The bell has been adapted to cooperate with different bell wirings -
switched on both through short-circuit (Fig. 3a) and also through
supplying the voltage of ~230V (Fig. 3b). If it is possible to select a type of
wiring (for instance, in new or renovated flats), then we suggest using the
installation switch on through short circuit it does not require to be
connected to a bell and a voltage switch, which makes the bell work
independent of the power grid and eliminates any possible electric shock
(even in such extreme case as, for instance, breaking of the casing or
pulling out the switch-key from the wall).

INSTALLATION
The bell is installed on the wall or a ceiling in the place, to which the wire
from the bell switch-key is delivered. In order to make a correct
installation, the following steps should be made successively:
1.Take the bell out of the package, remove a small flap and unscrew the
bolt connecting both parts of the bell (a bottom and a cover).
2.Apply the bottom to the surface, on which the bell is to be installed, in the
way ensuring that the wire of the switch-key gets into one of the cable
holes and mark with a pencil 3 longitudinal installation holes (see Fig. 1).
3.Put the bottom aside and bore the holes with a diameter of 6 mm in the
marked places, and then mount the plastic anchors, which are in the kit.
4.Screw down the bottom to the mounted anchors (through the
longitudinal installation holes) by threading the wire from the switch
through one cable holes.
CAUTION !!! In the case of installing the bell on the uneven surface, the
bolts should be screw down to the extent ensuring that the bottom will
not distort (this would make closure of the cover impossible).
