To open the detector box, use a flat-blade screwdriver no. 5 (8 mm). Smaller flat-blade screwdrivers may
damage the material of the rotary snap locks.

To actuate the rotary snap locks , press them firmly with the screwdriver towards the housing base and then
turn through 90°. The position of the lock slit shows the current status (see Fig. 15 ):
⇒
approx. 45° angled toward detector housing corner = closed;
⇒
approx. 45° angled toward detector housing edge = open.
In either position the rotary snap locks must snap into place.

The positions of the fastening holes are shown in dimensioned drawing Fig. 14 . When fastening to masonry, use the S6 dow-
els supplied.
