Installation/Configuration Notes
Installation notes
•
Head-on or parallel flush mounting.
•
The magnet should be fixed in the bore.
•
Head-on installation in ferromagnetic materials is
possible with the EG1 flush-mount housing.

Connecting LSN contacts
•
Each LSN contact is a physical LSN element (1 out of
127 possible per loop).
•
The length of LSN contact connection cables must be
included when planning the total line length of the LSN
loop, as LSN technology is incorporated in these
detectors.
•
Passive coupling elements for joining the connection
cables to the installation cable must be placed as close
as possible to the LSN contacts. The 1 m connection
cable with 2 m LSN cable length is included in the
calculation of the LSN cable length (LSN is carried into
the contacts and back out again).
•
Connector boxes (optional) are classified as installation
material.
Testing LSN contacts
•
Reed switch and microswitch functions can be checked
before installation by a high-Ohm multimeter or
continuity checker (for diode paths).
•
The resistance values are approximate values; a large
change in resistance is significant here.

Contact open: approx. 3 megaohm
Contact closed: approx. 1 megaohm
Note
Only the intrusion contact can be checked in
this way. The tamper switch of the Class C
magnetic contact can be checked by the LSN
control panel or with the LSN testing device
(software version 3.x onward).
