The shaft 29 of the Head screw 28 penetrates a hole 31 in the rear wall of the housing 24 and the slot guide 22, during the Head 30 of the head screw 28 on the inside of the rear wall of the housing 24 is present. The two clamping pieces 26 are advantageously as sliding blocks guided in the slot guides 22 32 formed. The slot guides 22 extend over an arc angle greater than 45.

To align the housing 11 on the holder 10 are the two Loosen head screws 28. Now the housing can 11 can be pivoted, the sliding blocks 32 and the cap screws 28 screwed therein being in the slot guides 22 move. The maximum swivel range is - as mentioned - 45 °. In the desired position of the housing 11 the two head screws 28 must then be tightened again ·. Loosening the head screw 28 and with it that The housing 11 can only be pivoted when the upper housing part 15 has been removed.

As can be seen from Fig. 4, the upper part of the housing latched onto the lower housing part 14. For this purpose, on the one hand and on the upper edge of the upper part of the housing 15 Front panel 16 on the other hand, each spaced apart locking elements 33 and 34 provided, which at

mounting surface 12 emerging electrical 'supply lines

45 to the danger alarm system arranged in the interior of the housing 11 (Fig. 1). These electrical supply lines are completely covered and without dismantling the assembly box inaccessible.

On the back 41 of the holder 10 there are still two through holes 46 for one fastening screw 47 each. These through holes 46 are as bores provided in two transverse ribs 48 arranged at a distance from one another. The transverse ribs 48 extend from the Back 41 of the holder 10 up to the guide section 21 and are shaped there after the latter. So they are Through holes 46 for the fastening screws 47 only accessible from the front 20 of the holder 10 with the housing 11 removed.

For attaching the mounting box to the mounting level 12 or on the room wall 13 are initially the holder 10 and the housing 11 by unscrewing the head screws 28 to separate from the sliding blocks 32 from one another. For this purpose - as already described - the upper part of the housing 15 be removed from the lower housing part 14 beforehand. Now the holder 10, which is separated from the housing 11, is attached to the fastening. Level 12 attached and by means of the through holes

46 penetrating fastening screws 47 in the wall of the room 13 attached. Then the electrical leads 45 are through the recess 43 in the holder 10 and through the through holes 44 in the rear wall 24 of the housing. Thereafter, the lower housing part 14 is with place its convex surface section 19 on the guide section 21 of the holder 10 and the cap screws 28 through the bores 31 in the housing rear wall 24 and through the slot guides 22 in the internally threaded bores 27 to be screwed into the clamping pieces 32. The lower housing part 14 is in the desired position inside

half of the available swivel range of 45 to align on the holder 10, and the cap screws 28 are to be tightened., so. that the lower housing part 14 no longer can be moved. The upper housing part 15 is then to be snapped into the front plate 16 and with its tabs 35 to be clipped into the latching lugs 37 in the lower housing part 14. That’s the case. 11 closed., Neither the mounting screws 47, the head screws 28 and also not the supply lines 45 are accessible without opening the housing 11. Manipulating this requires removing the Housing upper part 15, whereby - as already described "the sabotage protection switch 40 enters into activity.

To despite the limited range of relative pivoting mobility of the housing 1.1 to the holder 10 of 45 ° a swivel range of the housing 11 of 180 ° with respect to the mounting plane 12 must be reached. the fastening of the holder 10 to the B. fastening plane 12 in two each around 180 ° mutually rotated positions take place. In the same way, the housing 11 must be 180 ° against each other in two rotated positions are attached to the holder 10. This is illustrated in Fig. 3-, where for better recognition of the various swivel positions Housing lower part 14 s.ch. is refractory. - -

The position shown on the left in FIG. 3 is referred to here as the basic position. In this position the housing can be swiveled from a swivel position Q ° (parallel to the mounting plane 12) by an angle of 45 ° (dash-dotted line, shown). Should now the Montageb.px be aligned to an area _; can, which lies between this maximum swivel range of the housing 11 of 45 and a swivel angle of 90 °, so the housing 11 is to be removed from the holder 10 in order to ..18 ° _ to. .tre.hen and again on the holder 10 to fasten., all of this _; 12 .unverändert..g§haltene at .an de.r _{.B.efestigungsebene;} m, holder, 1 0 ....

the housing 11, as in the second position in Fig. 3 schematically is indicated, in a swivel range from the position shown in solid lines with a swivel angle compared to the mounting plane 12 from 90 ° to the The position shown in dash-dotted lines must be aligned with a pivot angle of 45 °.

The third and fourth positions of the housing box correspond to the arrangement of housing 11 and holder 10 to each other the second or first position. Here, only the holder 10 together with the housing 11 is opposite the second or first position rotated 180 ° around its longitudinal axis.

Because of this different arrangement of the holder 10 on the fastening surface 12 and because of the different relative positions Assignment of holder 10 and housing 11 to one another, it is possible to mount the mounting box so that it is within an angular range of 180 ° to the mounting plane can be aligned.

The front panel 16, which can be separated from the housing 11, is also used with the already mentioned detector or motion detector with further components, in particular those from Control devices, such as lamps or the like. Equipped. These Components are connected to the assemblies located in the interior of the housing 11 via electrical connecting lines connected to the alarm system. For repair or for It is the replacement of components of the alarm system necessary to remove the front panel 16 from the housing 11 in order to improve the accessibility and accessibility. So, on the one hand, not all electrical connections between the interior of the housing and the front panel 16 must be solved and on the other hand the electrical connection lines or their connections not through the freely hanging front panel 16 are loaded, the latter is designed to be foldable. To this end, the

130045/0405 ORIGINAL BATHROOM

Front plate 16 has two angled tabs 49 ″ projecting transversely therefrom. The angular tabs 49 are on both Arranged on the sides of the front panel 16, protrude into the interior of the housing and are angled downward in the plane of the flap. At the end, the two angled tabs 49 each have a guide pin 50, ″ that of the angled tab 49 protrudes transversely 'and preferably up to the housing side wall 39 protrudes ". A rib 51 protruding into the interior of the housing" is arranged on each housing side wall 39, their rear boundary surface facing away from the Froritplatte 17 52 a stop for the guide pin 50 forms. The rib 51 extends from the housing bottom 53 the entire height of the side wall 39 of the lower housing part 14.

On each housing side wall 39 there is one transversely protruding therefrom Locking web 56 is provided, which is arranged offset at a distance from the rib 51 into the interior of the housing is. The distance between the locking web 56 and the front end of the housing 11 is selected such that that with the front plate 16 attached to the lower housing part 14, the guide pin 50 on the facing away from the front plate 16 The rear of the locking bar 56 is in contact (Fig. 4). The locking web 56 also extends like the rib 51 from the housing bottom 53 eus upwards. But its height is many times smaller than that the rib 51 and corresponds to the embodiment described here approximately the diameter of the guide pin 50. The locking web 56 effects an additional locking of the front plate 16 on the housing base 53, so that the former does not overcome the latching elements 54, 55 can be lifted off the lower housing part 14 on its underside. When the front panel 17 pivot the guide pins 50 on the angle tabs 49 over the two locking webs 56 and come to rest on the rear boundary surface 52 of the ribs 51 (Fig. 5). The lower housing part 14, the upper housing part 15 and also the front plate 16 with angled tabs located thereon 49 are each made in one piece from plastic. The angle tabs 49 can therefore to a small extent rebound, which may be sufficient for the guide pins 50 to slide over the ribs 51 and the front panel 16 can fall off in the folded-down state. To avoid this, 39 is close to the two housing side walls a guide web 57 is arranged in each case. The two guide webs 57 are parallel to the side walls 39 and in Spaced therefrom. This distance is slightly larger than the sum of the length of the guide pin 50 and the thickness of the angle tab 49 carrying the guide pin (FIG. 6). These guide webs 57 prevent this

above-described rebound of the angle tabs 49 so that they cannot slide over the ribs 51.
The height of the guide webs 57 measured from the housing base 53 is dimensioned such that the guide pins 50 are still in the region of the guide webs 57 in the pivoted position of the front plate 16 (FIG. 5). The guide webs 57 extend as far as the locking webs 56 and even further beyond them, so that the guide pins 50 engaging behind the locking webs 56 cannot rebound here either.
