Relay Outputs - G-U BKS B-1893 Serie Manual De Instalación

If a voltage loss occurs during the motor-driven daytime release, the points described
under 4.3 apply.
If a control signal is still applied once the power supply has been restored, the lock adopts the
corresponding release mode once again.

Fig.16: Installation
Signal contact 1 ("Locked by motor" position reached)
Signal contact 1 (terminal 41 and 51) closes as soon as the motor-driven shoot-bolt lock has reached
its initial position. During this process, the latch and deadbolt triggers are retracted and the top and
bottom locks move to the locked position. The actual automatic locking operation of the passive leaf
is only performed once the passive-leaf control lock B 1895 has been triggered by the closing door
leaf.
Signal contact 2 ("Unlocked by motor" position reached)
Signal contact 2 (terminal 42 and 52) is closed as soon as the shoot-bolt lock has been driven by the
motor to the final position of the actuated release mode.
Deadbolt monitoring (only B-1893x)
The deadbolt monitoring signal is output potential-free via the deadbolt monitoring relay contact
(terminal 43 and 53) as soon as the deadbolt of the active leaf lock engages in the shoot-bolt lock.
If the deadbolt monitoring is actuated when the deadbolt is moved manually to the locked position
(with B-18xxx), control signals are not processed at the inputs I1 and I2. This means that the door
cannot be unlocked by the motor.
Latch (latchbolt) monitoring
The latch or latchbolt monitoring signal is output potential-free via the latch(bolt) monitoring relay
contact (terminal 44 and 54), as soon as the latch or latchbolt of the active leaf lock engages in the
shoot-bolt lock.
