ISP-EMIL-120 LSN Expansion Module

F.01U.076.548 | V3 | 2008.10

Installation manual

Bosch Sicherheitssysteme GmbH

Functional description
The LSN expansion module can be used to connect 6 detector zones (conventional detectors or monitoring 

contact inputs), for control purposes (4 control outputs) or for connecting arming devices (e.g. NBS 10) with 

system components to the local security network (LSN). The LSN Expansion Module has been developed for 

connection to LSN control panels, e.g. MAP 5000, and provides the extended functionality of LSN improved 

technology. The LSN mode "classic" can be selected via the integrated DIP switch (default setting), enabling 

the connection of all classic LSN emergency call detector control panels such as NZ 300 LSN, UEZ 2000 LSN 

and UGM 2020. A maximum of 2 x IMS-RM relay modules can optionally be installed in the expansion module 

housing (2 relays per relay module, 2 switch contacts per relay), if the switched control elements cannot be 

directly controlled from the expansion module due to the high current requirement, or to enable zero-potential 

switching. A wall tamper contact can be installed, if required (optional).

Installation

Connection terminals, relay module (optional) and wall tamper contact (optional): see Fig. 4, page 8

Address setting

The address of the expansion module is set via the 8 DIP switches on the connector board using a suitable 

pointed implement. 

5.

The DIP switch settings for all permissible addresses are listed in the diagrams and the tables below 
(1 = on, 0 = off): see Fig. 5, page 9 and tables below.

NOTE! Installation to be performed by authorized specialized personnel only!

!

WARNING! Current-carrying components and isolated cable. Danger of injury 
through electric shock. The system must be free of current when connecting.

CAUTION! Electrostatic discharge (ESD) Electronic components may be damaged. 
Attach grounding wrist strap or take other suitable measures.
