System Overview
The SE 120 LSNi SmartKey arming device is a system solution for arming intrusion systems. The
individual components of the system can be put together as required for the intended usage.
Operating modes with or without the SPE blocking element are possible. Control authorizations
for arming/disarming are defined during control panel programming.
SPE blocking element
The SPE blocking element is an additional
lock for the door and is meant to prevent
unauthorized entry to the armed area. The
SPE blocking element is always installed in
the armed area in conjunction with a kit to
enable it to accommodate different doors
(the image shows a door-mounted installa-
tion; for other variants, please see installing
the SPE blocking element). A conventional
magnetic contact can be used with the
door-mounted installation kit.
Operation types with and without blocking
elements are possible.

SmartKeys
There are two types of SmartKeys
Keys with a security card
Standard key (without security card)
Key with security card: the system operates like a locking device. The key kit consists of a
set number of valid keys and a security card. The control unit is initialized using the security
card and accepts only the keys of the key kit. To order additional keys, the security card must
be sent to the manufacturer together with the order. The keys are labeled with a consecutive
key number, a security card number and an 8-digit identification number.
Standard key (without security card): the keys are not numbered and can be read in as of-
ten as required. The keys are labeled with an 8-digit identification number.

System Description
SE 120 LSNi control unit
The control unit processes the status re-
ports of all components in the system,
communicates these reports to the intrusion
alarm system and controls the SPE blocking
element. The control unit is installed in the
secure area.
Reader
The system is armed and disarmed by hold-
ing an electronic key up to the reader. The
LED and buzzer provide information about
the status of the system as well as opera-
tion.
The reader can be surface mounted or re-
cessed mounted (outside the secure area).
Bolt contact
A conventional bolt contact can be con-
nected to the control unit. The bolt contact is
not included in the scope of delivery.
Magnetic contact
A conventional standard magnetic contact
can be connected to the control unit. The
magnetic contact is not included in the sco-
pe of delivery.
Note: Conventional contacts are the rec-
ommended contact type as they can be
processed directly by the control unit.
