ELECTRO-MECHANICAL SECURITY LOCK
Please make sure the following installation requirements are met to ensure the correct functioning of
your B&B A1 electro-mechanical lock :
Use BB25LSZH cable (2 x 1,5mm² + 5 x 0,22mm² - shielded).
Use 24V DC regulated POWER SUPPLY of minimum 2,5A per lock.
Make sure the distance between the power supply and the lock is maximum 25m.
Measure the voltage coming to the lock and make sure that this never drops below 22,8V (24V DC +/-
5%) - important especially when the solenoid is activated! In case of a voltage drop on the line
one can increase the TRIM 2 on the PS24D52 power supply (factory setting = 2 ).
Make sure the distance between the lock and striker plate is min. 2mm and max. 6mm.
Make sure the lock and striker plate are installed in a proper matter where the 2 are perfectly aligned
(in closed door position they should be straight across from each other, both laterally and in
height).
Make sure that there is no friction on the bolt when being ejected and retracted (this should be tested
after installation of the rubbers on the profile).
Make sure the holes for inserting the cylinder are large enough so the cylinder can be easily installed
without being forced.
Only cylinders with the lever at 5 and 7 (o’clock) can be used:
Filings that end up in or around the lock will be attracted
when the solenoid is activated and will eventually damage the lock. Compressed air can be used
to clean out the lock if necessary.
Do not use grease or oil in the locks. The necessary areas have been libricated during the assembly at
the factory.
A standard revision is recommended aftre 300'000 cycles or 5 years.
Make sure the door is equipped with adequate hinges (according to door size and weight) to avoid
„hanging“ of the door.
Make sure the door is equipped with an adequate door closer (according to door size and weight) !
DO NOT FILE with the lock already installed!
Please note that in order for the lock to function correctly the above mentioned specifications need to
be strictly followed. B&B LOCKS b.v.b.a. can not be held accountable for on-site interventions and
reparations under warranty if the installation was not done according to these specific instructions !
min. 2mm
max. 6mm
