DC POWER SOURCE
WARNING: In order to prevent voltage spikes generated by magnetic lock or DC powered strikes from
being induced into the system, it is strongly recommended that a 1N4001 diode be installed
across the magnetic lock coil, so that the cathode of the diode (the end with the band) is
connected to the positive connection of the coil and the anode is connected to the negative
connection of the coil.
