The B-1893x or B-1993x motor-driven shoot-bolt lock can be operated with a
nominal current of 2A-4.2A.
The amount of operating current depends on the loads exerted on the door leaf.
If only low loads are anticipated due to gasket sealing forces, wind load, draught, etc., a correspon-
ding power supply unit with low output can be used. A power supply unit with a higher output is
therefore especially recommended at external doors and in staircases.
The diagram below can be used as a decision-making aid. The green area represents the operating
range of the motor-driven shoot-bolt lock.
