Installation/Configuration Notes
Installation notes
•
Installation is carried out in the door bolt with the bolt
contact being activated by the tongue of the lock. It
should be kept in mind that only the second turn of the
key in the lock actually activates the contact. To make
any necessary adjustments, the bolt contact's operating
spring lever can be bent.
•
When installing in fire protection doors, please ensure
that no mechanical changes, except for the fastener
bores, are carried out on the door frames.
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.
1 Detector
2 High-Ohm multimeter
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).
