Without operating voltage
, the outside lever handle is coupled (closed-
circuit principle).
With operating voltage
, the outside lever handle is decoupled and can be
coupled via an additional control signal (e.g. via a switch).
Alternatively, it is always possible to couple the outside lever handle
temporarily through the built-in locking cylinder by turning and holding the
key. As soon as the key is released, the outside lever handle is decoupled
again.
The following lock functions are available as potential-free contacts:
Latchbolt (locked or not locked) *
Position of the cylinder cam / key (actuated)
Outside lever handle (actuated or not actuated)
Inside lever handle (actuated or not actuated)
2.3.1.2 Closed-circuit principle (fail-secure)
The following lock functions are available as potential-free contacts:
Latchbolt (locked or not locked) *
Position of the cylinder cam / key (actuated)
Outside lever handle (actuated or not actuated)
Inside lever handle (actuated or not actuated)
* Only SECURY 1970.
SECURY 1971 does not have a latchbolt contact. The latchbolt cannot be queried through the
shoot-bolt lock B-1990X-XX-X-X FSK (
