Secury 2170 / 2171 (Electrically Couplable) - G-U SECURY 21 EK Montageanleitung

2.3.1 SECURY 2170 / 2171 (electrically couplable)

Basic functions
The multi-point lock is equipped with an automatic lock (panic function C,
see general instructions M -00090-00-0).
EN 179
Opening the door in escape direction is possible at any time.
2.3.1.1 Open-circuit principle (fail-secure)
Without operating voltage, the outside lever handle is decoupled (open-
EN 1125
circuit principle).
By applying operating voltage (e.g. via a switch), the outside lever handle
can be coupled.
Alternatively, it is always possible to couple the outside lever handle
through the built-in locking cylinder (key).
The following lock functions are available as potential-free contacts:
„ „ Position of the cylinder cam / key (initial position or actuated)
„ „ Outside lever handle (actuated or not actuated)
„ „
Inside lever handle (actuated or not actuated)
2.3.1.2 Closed-circuit principle (fail-safe)
Without operating voltage, the outside lever handle is coupled (closed-
circuit principle).
By applying operating voltage (e.g. via a switch), the outside lever handle
can be decoupled.
Alternatively, it is always possible to couple the outside lever handle
through the built-in locking cylinder (key).
