To dispose of old electrical or electronic
devices, you should use the return and collec­tion systems put in place in the country con­cerned.

Short information

This zone expander module integrates manual
conventional sensor technology (e.g. conven­tional magnet contacts) into the local security
network (LSN).

How to close the zone expander module

1. To close the zone expander module, put
the housing cover onto the mount with
PCB while ensuring that the insertion
post (element 3 in figure above) on the
lower side of the housing cover fits into
the designated opening for the insertion
post (element 4 in figure above) on the
mount with PCB. Do not force the inser­tion post into any of the other openings.

2. Secure the housing cover with the hous­ing cover fastening screw.

3. Put the adhesive seal onto the housing
cover fastening screw.

Connection

!

Caution!

Incorrect cabling
Incorrect cabling leads to malfunction
of the system.

!

Caution!

Cable length
Exceeding the permitted cable length is
not covered by CE declarations and
leads to malfunction of the system.

– Do not exceed the total cable length of

500m for the primary cables, the control
cables and the contact cables of EM 55,
KD55/1, NKK, NNK 100 2-wire, NVK and IC

400.

Permitted cable length of the primary cables
(PL)

– Maximum length of one unshielded cable:

3m

– Maximum length of all shielded cables: 500m

LSN connection

– Voltage supply can be fed-through (other-

wise free terminals for 0V/+U).

– Incoming and outgoing LSN can be swapped

over.

4-wire and 2-wire connections

Notice!

A mixed operation of a 4-wire connec­tion at one of the primary outputs and
a 2-wire connection at the other
primary output is not permitted.

Notice!

For a 4-wire connection always use un­shielded cables.
For a 2-wire connection always use
shielded cables.

4-wire connection (unshielded)

– Use a 4-wire connection with an unshielded

cable with a maximum length of 3 m and the
internal EOL resistor (e.g. for magnetic con­tacts).

– With an unshielded cable, do not connect

contacts with metallic enclosure.

2-wire connection (shielded)

– Use a 2-wire connection with a shielded

cable with a maximum length of 500 m and
an external EOL resistor (e.g. for lock con­tacts).

– Connect shielding only to the zone expander

module.

– Use one ferrite bead per shielding.
