The motor-powered blocking- and locking element prevents access to the armed zone
of an intrusion detection system. (IDS).
The use of a blocking element has the following advantages:
An IDA can be armed by different arming elements at different positions.
Access to the secured zone can be prevented or authorized at one or several
It is easily mounted in the door frame. Only a borehole is required in the door leaf
or the counter unit for the locking bolt and the magnet.
Integrated magnetic contact for monitoring of opening.
Actuation is either dynamic or static.
Electrical and mechanical emergency unlocking and a combination of both is
nhanced mechanical stability - no breaking point at the locking bolt. Shearing
force at side >3 kN.
VdS approval as final control element in access control systems.
When the operating voltage is applied, the locking bolt is always retracted which is
equivalent to the position "Access authorized" (OPEN).
An operating voltage interruptor switch could enable this simple electrical emergency
The locking bolt is extended with the static or dynamic control signal "CLOSE". The bolt
is also retracted with the corresponding control signals.
In case of inadmissible bolt counterpressure or should the bolt jam, an electrically
controlled correction takes place followed automatically by several new attempts.
The time the bolt requires to move depends on the operating voltage and ranges from
0.8 to 1.2 s at an operating voltage range of 9.0 V to 15.0 V DC.
If the locking bolt does not move into the "OPEN" position electrically, emergency
unlocking can be activated using a tool (e.g. Screwdriver).
