Important note
Under extreme (weather) conditions, such as a long and
persistent heat wave, the function may be impaired for
physical reasons.
1.
The housing
The two halves of the housing are fitted with an interlocking
device. The housing is then sealed by a seal.
-
Opening the housing
(fig. 1)
Pierce seal using a small screwdriver or something similar
(A) and remove (B). Push the top half of the housing briefly
upwards (C), so that the sliding mechanism can unlock. Pull
the top half of the housing downwards until stop pin is
reached and then remove (D).
-
Closing the housing
(fig. 2)
Replace the upper part of the housing and pull downwards
until stop pin is reached (A). Then push the upper part
upwards until the stop pin is reached (B).
2.
Mounting
2.1
Mounting position
Avoid:
* mounting above radiators (especially critical with long-
range- and curtain mirror)
* mounting near air outlet openings
(e.g. air-conditioning plants)
* direct sunlight
* nearness to fluourescent lamps
* nearness to incandescent lamps
2.2
Cable entry / tension relief
When entering the cable from above (F) the terminal clamp
is to be removed. A looped cable run serves as tension relief
for different diameters of cable. Depending on the thickness
of the cable it is laid clockwise or anti-clockwise around the
square (D).
In using the other cable entries (G) tension relief follows as a
result of cable joints, where the cables are pulled tight on the
bottom part of the housing. The cable joints are pulled through
the slots provided in the bottom housing component (E).
2.3
Wall mounting
(fig. 4)
-
0° vertically inclined
(fig. 4/1)
The device is fastened by using 2 screws: One under the
terminal clamp and the other through the small square in the
middle of the detector (fig.3/A).
-
3° vertically inclined
(fig. 4/2)
In this position the range is somewhat reduced. This is
specially recommended for small rooms.
Fastened with 2 screws in the lower part through 2 holes at
the same height (fig. 3/C).
-
45° horizontal to the left or to the right
Fastened through 2 holes at the side above each other.
(fig.3/B)
-
Corner mounting
(fig. 4/4)
Fastened through 2 holes at the side above each other.
(fig.3/B)
In fastening the bottom part with 4 screws there is a danger
that this no longer fits to the upper part of the housing due
to the tension caused by the screwing. To avoid this, the
bottom part may be fastened by using 2 screws only on the
one side.

Installation
A maximum of 63 detectors can be connected to each detector
group. After all work has been carried out the opening beneath
the housing is to be sealed with the provided plastic seals.
(see chapter 6.3)
The supply line should consist of shielded and paired
intertwined lines. For the necessary cross- sections please
read the installation instructions (chapter "circuits") of the
respective control unit.
The terminal clamp works according to the lift-principle and
has a plug-in protection for the connecting wires. A 2,5 mm²
cross-section is able to be clamped.
The connecting wires are to be stripped for a length of 10 mm
±1 mm.
If more wires are required per terminal clamp, care should
be taken to ensure that their diameter is of the same size to
guarantee a secure clamping (possible loose fitting and
twisting).
The shield connections have to be as short as possible to
avoid the danger of unintentional short circuits.
The principle of BUS-1 circuit wiring see fig. 5
Note:
The BUS-1 terminal technique requires no end of line
resistor.

Note:
Please read the installation instructions in chapter 3.
With
Version 1
the voltage supply is interrupted for the rest of the BUS
users. If this is not requested then
applicable.
5.
Programming
5.1
BUS-1 user address
The DIP-switch serves the purpose of coding the BUS-1
user address. As a logic detector the detector seizes a BUS-
1 address.

S1/6.

Using the DIP-switch S2 it is possible to program the
following parameters:
- range
- sensitivity

Start-up
6.1
Checking the installation
A requirement for reliable functioning is the satisfactory
installation of all system parts. Check all circuits in order to
recognize possible circuit breaks or short circuits.
Make sure that no earth leakage exists.
6.2
Walk test
Carry out a walk test with each detector.
The walk test method is described in the installation
instructions of the respective control unit.
6.3
Inserting the seal
While inserting the seal the top part of the housing has to be
pressed upwards so that the slider can snap in. The housing
is now locked and can only be opened by removing the
(fig. 4/3)
seal.
