Features
▶ Up to 6 UEZ LSNs can be networked with system loop
technology (SRT)
▶ Fire alarm peripheral elements can be connected in the
LSN loop
▶ 4 loop or 8 stub lines with UEZ 2000/1 LSN
▶ Max. 254 LSN elements with UEZ 2000/1 LSN
▶ 8 loop or 16 stub lines with UEZ 2000 LSN
▶ Max. 508 LSN elements with UEZ 2000 LSN
▶ TeleService capability
The UEZ LSNs are intrusion control centers designed for
monitoring medium-sized properties (monitoring area 6000
to 12,000 m² depending on specification).
The emergency call peripheral elements are connected via
the LSN (Local Security Network).
Both systems are equipped with an LVM 100.
• The UEZ 2000/1 LSN cannot be extended with an
additional LVM 100.
•
The UEZ 2000 LSN can be extended with an additional
LVM 100.

Functions
A combined operation of fire and emergency call is possible
within the framework of the control unit. In addition, a
combination of various LSN elements on an LSN line is
possible.
False alarm protection is provided by an internal program:
Alarm delay and/or dual detector/cross zoning (only with
smoke detectors).
Full functionality is maintained on the loop in the event of
short-circuit or interruption.
Encrypted data transmission is possible for the priority
Bosch control panel or in the SRT loop.
Message processing
In the LVM 100 line processing module, the information
from all LSN elements is scanned cyclically, and processed
and digitized by the line processors on the LVM. Information
prepared in this way is transmitted via interfaces from the
line processing units to the ZVM 100 central processing
module; at that point it is analyzed and generated as a
message, for example to a display/operating panel,
recording device, priority Bosch control panel, etc.
