Installation
· The SL2000 code lock should be mounted near the supervised door on a vertical piece of supporting
structure.
· Assure that the surface beneath of the controller’s rear panel is flat and smooth.
· Disconnect power supply before making any electrical connections.
· Once installed and electrically connected, the unit has to be properly programmed.
· When forgotten, MASTER and INSTALLER codes can be reprogrammed through Memory Reset procedure.
· The code lock must be supplied form reliable power supply, calculate the adequate wire gauge to guarantee
that the voltage dropout between the power supply and the DC input of SL2000 will not exceed 1V in the
worst case.
· It is recommended to supply door release device (e.g. door strike or magnet lock) and SL2000 from
separate power supply but when both code lock and door release device are supplied from the same power
source you must use separate pairs of cable to supply each of them.
· Always add the silicon diode (e.g. 1N400x series) in parallel to door release device – locate diode as close
as possible to door release and as far as possible from the code lock.
· It is forbidden to supply the door release device directly from the DC input terminals of a code lock.
· Do not attempt to use Door Relay output for switching of a voltages higher then 24V DC/AC.
