DM25
1.

GENERAL DESCRIPTION

The DM25 microwave movement detector has been created for controlling the opening of automatic gates. It can detect
movement of persons or of greater masses, such as vehicles of all kinds, over surfaces from one to fifteen square
metres.
This versatility is due to the possibility of adjusting range by means of the special setting trimmer (E Fig. 1).
Basically the DM25 consists of a signal receiver-transmitter. Each device has a LED (D Fig. 1) in SMD technology, not
visible externally, which indicates detection of movements and the state of excitation of the relay.
Its high-level protection box (IP55), its considerable setting range by means of the special trimmer (E Fig. 1) and vertical
setting by means of the special slots (A Fig. 1) mean that the DM25 can be perfectly applied to automatic gates both
externally and internally. Adjusting the settings mentioned above it is also possible to tare the detector in such a way as
to detect only masses of a certain size, such as vehicles of any kind.

4. ASSEMBLY INSTRUCTIONS
The DM25 must be installed in locations and on surfaces free of vibrations, protected from inclement weather and
accidental knocks and at a height of around 2.5 metres from ground level. Installation must be carried out following the
instructions shown in Fig. 1 and the diagram in Fig. 2.
Using the trimmer (E Fig. 1), set the desired range. You are advised to set the range in such a way that there is no
detection of movement lower than approximately 20 – 30 cm. from the ground level being covered.
This precaution is advised in order to reduce the amount of interference generated by vibrations which might interfere
with normal functioning of the DM25.
