2.4.1 Opening and closing the detector housing
Notices about opening and closing
• To open the detector housing, use a flat-blade screwdriver no. 5 (8 mm). Smaller flat-blade screwdrivers
may damage the material of the rotary snap locks.
• To use the rotary snap locks , press firmly with the screwdriver toward the housing base and then turn 90°.
The position of the lock slit shows the current state (see Fig. 2 ):
⇒ approx. 45° angled toward detector housing corner = closed
⇒ approx. 45° angled toward detector housing edge = open
The rotary snap locks must snap into place.
• The housing cover (control unit) is connected to the Main Board by a flat cable . Make sure that when the
housing cover is lifted away the flat cable does not become damaged.
Fig. 2 Opening, closing and fastening the detector housing
After the detector housing is open, the four mounting holes in the housing base are accessible. To facilitate mounting work,
remove the entire housing cover of the detector housing (including control unit). To do that, pull off the 10-pin flat cable con-
nector from the AMB 35 Main Board.
The detector housing is fastened with the four supplied Torx wood screws (Ø 4.5 x 35 mm) and the four U-washers
(Ø 4.3/12 x 1 mm), “ A ”. Use a Torx T20 screwdriver to insert and tighten the screws.
The positions of the fastening holes are seen in dimensioned drawing Fig. 1. When fastening to masonry, the supplied S6
dowels are used.
Notice
When mounting several ASD 535 units next to each other, it is important to ensure that the mounting holes are
drilled precisely . The device can be moved a maximum of ±2 mm horizontally and vertically to correct the
mounting position. A rotation correction of approx. ±5 mm is possible.
