First, be sure the lock is being powered by a DC source and that polarity is correct (RED to positive DC BLACK to negative DC). If the Magnalock is wired in reverse polarity, it won't be damaged, but it will not operate.Second, if the unit continues to appear dead, it must be electrically checked with an Ammeter. It must be powered with the correct input voltage and checked to see if it draws the specified current. If the unit meters correctly, then the magnet body is operating properly and the problem must lie in the mounting of the strike.
The SAM operates by pulling the strike plate against the magnet face when the door closes, seating the conical buttons on the strike into corresponding machined holes at either end of the magnet body. If the buttons do not seat, the lock will not hold. There are three potential causes that can produce a failure of the buttons to seat. First, the mounting alignment between the strike and the magnet body can be off so that the buttons don't line up with the conical machined holes in the T brackets. A misalignment greater than 1/8 inch end to end or front to back will cause engagement failure. You can normally visually detect such an alignment problem. Watch the strike closely as you very slowly close the door. You should see it "try" to move against the magnet body but note that the buttons are acting as stand-offs because they are not lining up with the holes. In some cases, this problem can be corrected by adjusting the door but re-mounting the unit properly is often required. The second possible cause is that the gap between the magnet body and strike plate has widened to the point that the magnet can no longer pull the strike plate in. This can happen, for example, when the lock is mounted at the top of the door and the door sags downwards which increases the gap. Note that the gap is supposed to be 1/10 inch or the point at which the tops of the buttons just graze the magnet surface. If the actual gap is significantly greater than this, you have found the problem. It can be corrected by either readjusting the hanging position of the door or readjusting the level of the strike (by turning the two strike mounting screws) so as to reduce the gap to the correct dimension. The final possible cause is that the strike mounting hardware has somehow become frozen so that the strike has lost its movement ability towards and away from the magnet body. You can check this by trying the move the strike by hand with the door open. If it will not move, dismount it and clean and lubricate (or replace) the mounting hardware.
First, Check the strike and magnet face to see if something is interfering with a flat fit.Second, the strike must be allowed to float around the rubber washer stack which must be on the strike center mounting screw. The magnet then pulls it into flat alignment if the strike is mounted to rigidly proper alignment can't occur and the lock won't hold. To correct the problem, try loosening the strike mounting screw to see if the lock then holds properly.Third, if you are operating the lock on AC instead of DC or on half wave rectified DC (transformer + single diode) the lock won't hold. Half wave rectified DC is unacceptable; you must, at a minimum employ full wave rectified DC (transformer + bridge).
First, make sure that it is not reporting secure because a small obstruction or too stiffly mounted strike is causing the Magnalock not to hold properly. This problem can be corrected by cleaning the surfaces of the magnet and strike or establishing proper play in the strike mounting. Second, you can verify function of the Senstat feature as follows. Note that the core is separated into 3 sections from left to right. The Senstat output is created by the strike establishing electrical contact between the leftmost and rightmost core segments. With the lock powered, use a conductor to connect the two outside segments. If the Senstat reports secure then the strike plate is not making proper contact with the lock face. If using a conductor doesn't cause the lock to report secure, check to see if there is a broken Senstat wire. If not the lock must be returned to the factory for replacement.
When power is removed the Magnalock must release. If internal circuitry were to fail completely, the lock would only exhibit "stickiness" at a rough level of 5 pounds.First, make sure that power is being removed from the Magnalock by the control device using a meter. If voltage is not dropping to zero check your control switches and wiring.Second, check the face of the Magnalock and the strike plate for foreign material. Any material found should be removed using a piece of cloth and a non abrasive cleaner.
Electric locks return voltage spikes on their power wires and also emit microwave radiation when switched. Note that Magnalocks include internal electronics which suppress both inductive kickback and radiation. First, check the access control equipment it may be faulty or have been installed improperly. Second, a problem can arise with the Magnalock. If the Senstat version is being used, the strike plate (which passes current) must be isolated from a metal door and frame. Securitron supplies insulating hardware to accomplish this but the hardware might not have been used or the strike may be scraping against the header for instance. Check for full isolation between the strike and the door frame (when the door is secured) with an Ohmmeter. The presence of lock voltage potential in the door frame can interfere with the ground reference of access control system data communication and therefore cause a problem.
