If necessary, the alarm can also be secured using a number 2 or 4 thread-cutting screw
(diameter of 2-3 mm – not included) with a length of 6-8 mm (see Figure 12d). This
will fix the alarm to the mounting plate (see Figure 12c). First attach the alarm to the
mounting plate.
Insert the screw (not included) into the “U”-shaped recess shown in Figure 12c and
screw it down firmly.
To remove the alarm from the ceiling, first remove the screw and then turn the
alarm anticlockwise.
