Mounting Location and Installation
The power and flexibility of the
H
uman Detector
Flex
alarm system, amongst others, lies in its wireless radio
connection. Due to the transmission frequency and protocol, a high level of security is ensured. The modulation
process contributes to an increased range compared to products from various competitors. To ensure unrestricted
wireless radio operation, a few basic rules should be observed:
·
Do not mount the sensor module directly on metal surfaces or parts.
·If this is not possible, a minimum distance of approx. 40 cm should be kept from the metal surface.
This is important to ensure proper radiation of the transmitting antenna.
·
Choose an installation position of the sensor module so that there are no large metal parts between
the module and the radio control unit. This is critical, for example, when the sensor modules are
placed in display cases or vehicles.
·Choose an installation location so that you have access to the sensor module at all times. This is
necessary, for example, for checks and changing the batteries.
·Under no circumstances may unauthorised persons have free access to the sensor
modules. An exception can be sensor modules that inevitably trigger an alarm in the event of
contact (such as
HDF-OPTICAL
,HDF-TOUCH
and
HDF-3D PROTECT). Access by unauthorised
persons, however, should only be possible in exceptional circumstances.
Note:
The distance of 40 cm to metallic surfaces and parts can be reduced, if it is not possible to maintain this distance. In
this case, however, you should check the stability of the radio link very carefully.
Choosing the location for installation
The
HDF-DOOR
alarm module consists of two parts. Both, the sensor module and the permanent magnet, can be
fitted with two screws each. It is recommended, in many cases, to bond the two components to the surface at the
installation location, e.g. useful for aluminium framing.
We recommend double-sided adhesive mounting tape for fixing:
WÜRTH item: 0894909094
and
0894909005
(without guarantee)
This tape is transparent, adheres well to various surfaces, is largely emission-free and can be removed without
leaving any residue.
The sensor module must be mounted directly on the frame of the door edge or flap; the permanent magnet
accordingly on the door or flap. The position of the magnet in relation to the sensor housing is printed on. It is
important that the permanent magnet is in the correct position near the sensor housing. The distance must not
exceed 10 mm.
The
HDF-DOOR
alarm module triggers an alarm both when the door or flap is opened and when it is closed.
Note:
We recommend placing the permanent magnet on the moving door or flap. If the sensor module were to be installed
there, it could be damaged when the door is slammed.
