08) If it is necessary to prevent unauthorised removal of the smoke
detector, then the removal protection mechanism should be enabled
to lock the smoke detector onto the base. To do this, cut out the pre-
punched section on the detector housing using a suitable knife
(see "Installation and User Manual - Smoke alarm device Dual/VdS").
The locking mechanism can now only be opened using a tool.
09) Insert the smoke detector into the 230 V base and lock in place by
turning gently clockwise.
10) Carry out a function test (see "Installation and User Manual - Smoke
alarm device Dual/VdS").
Fitting the battery
If the battery is not in place, then it will not be possible to lock the
detector into the mounting plate or base. Only use IEC 6 LR 61, 9 V
(Duracell Plus) block batteries in the smoke detector.
