Surface mounting
The IC 400 LSN universal expander connects conventional
motion detectors to the local security network (LSN)
Functions
The following detector connections to the IC 400 LSN are
available:
Expansion module inputs
•
1 freely programmable alarm input
•
1 tamper input
•
ETO fault, input for the electronic fault detector output
(ETO = Electronic Trouble Output) for some detectors,
permanently occupied
Expansion module outputs
•
Detector power supply
•
Walk test (Out 1) and alarm memory (Out 2)
(programmable via the control panel software)
LSN
In the event of wire interruptions or short-circuits, all LSN
elements in the LSN loop continue to be monitored. In this
case, the system automatically creates two stub lines that
continue to monitor from both sides up to the location of
the fault.
The module housing has a tamper contact that, if triggered,
sends a unique message and is evaluated as a sabotage
alert.

Installation/Configuration Notes
Expansion module power supply
The LSN part of all LSN elements (expansion modules and
detectors) is supplied with power via the control panel's 2-
wire LSN line.
All LSN expansion modules are designed to loop through
the power supply (+V, -V) of subsequent expansion
modules.
The maximum cable length of the separate power supply
(+V, -V) depends on the current consumption of the
expansion modules to be supplied and their peripherals, if
not powered by an external source.
The applicable voltage range must be taken into account to
ensure correct operation of the LSN expansion modules.
Cable lengths
Cable length per primary line (PL) or control lines
•
Maximum length unshielded cable – 10 m
•
Maximum length shielded cable – 500 m
Alarm input
The alarm input is equipped with a window comparator.
Terminating this input with an 8.4 kilohm to 14.2 kilohm
(typ. 12 kilohm) resistor does not trigger an alarm. In all
other cases, an alarm is triggered. Imax = 0.5 mA
Tamper input
The tamper input is equipped with a window comparator.
Terminating this input with an 8.4 kilohm to 14.2 kilohm
(typ. 12 kilohm) resistor does not trigger the sabotage alert
message. In all other cases, a sabotage alert is triggered.
Imax = 0.5 mA
ETOin
Input for the electronic trouble output (ETO) for some
detectors.
Fault
Low: 0.0 to 0.8 V =, Imax = 0.12 mA
No fault
High: 2.5 to 5.5 V =, Imax = 0.12 mA
The unswitched input is terminated by an internal pull-up
resistor.
