The top of the strike should be positioned about 1 10 2 5mm below the line where the door meets the door stop or below the header if there is no door stop to permit free closing If the strike is mounted vertically instead of horizontally increase this stand off distance to 2 10 5mm More clearance is needed on a vertical mount because the strike projects out from the door and can scrape the side frame as the door swings closed on its arc Final positioning of the strike is dictated by the desired position of the magnet The strike must be centered on the magnetic poles 3 bars and the magnet is normally moved an inch or so in or down from the frame corner so that the magnet mounting holes will not have to be drilled awkwardly in the corner When the strike position has been chosen step two is to drill three holes in the door following the template Step three is mounting the white plastic bushings which surround and insulate the roll pins into the 1 2 12 7mm holes The bushings are employed to insulate the strike electrically from a metal door and also help prevent the roll pins from wearing the door Rev A 3 5 00 Page 2 FIG 1 STANDARD MAGNET DIMENSIONS AND ASSEMBLY If G option is furnished 62 and 82 series only the wire cable emerges from a 3 4 male 1 2 female conduit fitting on the end of the magnet The mounting holes are counterbored from both sides to make the magnet Length Width Depth non

6. BOTH LOCKS ARE SECURE 3 DOUBLE DOOR CONTROL SWITCHING It s common to control two locks from a single access and or exit switch on double doors or on an installation where two locks are mounted on a single door In nearly all cases this works with no problem but occasionally the release can appear to be sticky for similar reasons to those discussed in Section 3 3 This happens when one of the locks is poorly coupled to its strike plate This could occur because of an installation problem the strike plate is not being allowed to swivel or because of some obstruction between the plate and magnet surface When an electromagnet is not well coupled to its strike plate its magnetic field collapses so rapidly that it provides some energy to recirculate in the second magnetic lock slowing the release of that lock FIG 14 DOUBLE POLE SWITCHING OF TWO LOCK INSTALLATION TWO POLE MAGNALOCK 1 POWER MAGNALOCK 2 SUPPLY Rev A 3 5 00 Page 16 So if you notice slow release on a double lock installation this is telling you that one of the locks is not holding properly and that the problem should be corrected Alternately any chance of slow release can be eliminated by controlling the two locks with a double pole switch or relay This blocks the recirculation path and is shown in Figure 15 3 8 EMERGENCY RELEASE Magnalocks are often wired into a system such that they can be released in an emergency either manually from one s

8. force of the blow rather than transmitting that force to the lock In more technical terms the momentum of an object striking the door will generate momentary force at the lock as a direct function of the deceleration of the arriving object If the object decelerates abruptly because the door is very stiff it will generate a large force Slow deceleration as the door gives with the arriving object generates a relatively small force at the lock Once the above paragraph is understood we can conclude that the best place to mount the Magnalock on an inswinging door is at the top of the door header In fact this is best place to mount any lock on an inswinging door Most people prefer to mount at the middle of the door as it gives a feeling of security when one shakes the door from the doorknob This however is an illusion If a strong kick is struck right at the lock the power of the kick is transmitted nearly directly to the lock and there is a good chance of defeating the lock or its mounting If the lock is at the top of the door a kick at the door center causes the door to flex which absorbs most of the force of the blow The concept of preferring a door that gives also affects the issue of physical security on different door types Oddly enough the characteristics that make an inswinging door strong can make it more difficult to lock if it is stiff Steel doors and most particularly solid steel doors such as may be found in prisons transmit bl

11. periodic cases of an assault destroying the door but leaving the Magnalock intact and still holding a piece of the door This raises the question of whether it ever makes sense to install the model 82 Magnalock on non steel doors since the model 62 is stronger than the door Justification for using the model 82 lies in margin for error The greater strength of the model 82 can compensate for a dirt build up or improper installation and this may be warranted for the protection of critical areas Steel clad fire doors or solid steel door such as are sometimes found in prisons are generally stronger than the model 62 Magnalock so the use of the model 82 Magnalock can provide extra security for critical applications on steel doors In looking at methods of attack the first point that must be made is that it is far more effective to force the attacker to pull the door open rather than to allow him to push it This is controlled by whether the door swings away from or in to the protected area with the former being preferred If the attacker can be forced to pull the door it is much more difficult for him to generate the requisite amount of force to defeat any of the Magnalock versions A crowbar may be used to try to pry open the door At first this seems to be a major worry as a long crow bar can develop high force through leverage In fact what generally occurs is that the door experiences material failure The crowbar tears in the case of wood or bends

13. slows release A diode should never be connected as shown in Figure 12 Rev A 3 5 00 Page 14 The second problem is when any load is operated in parallel with the Magnalock A good example would be adding an incandescent lamp in parallel with the lock so that the lamp would be illuminated when the lock is powered The lamp acts like a resistor and allows current recirculation which will greatly slow lock release time When you want to add a resistive load in parallel with the lock you must put a forward diode in series with the resistive load Mi will block recirculation and restore quick release Correct practice is shown in Figure 12 elow A special case exists when you use an LED connected in parallel with the Magnalock to show that the Magnalock is on for example This does not slow release as the LED does not allow recirculation but the limited recirculation energy will eventually burn out the LED LED s are susceptible to even a tiny amount of reverse voltage Therefore add the forward diode as you would with an incandescent lamp See Figure 12 to extend the life of the LED FIG 12 WIRING CONSIDERATIONS TO AVOID SLOW RELEASE MAGNALOCK BLACK NEVER CONNECT PARALLEL REVERSE DIODE AS SHOWN USE A FORWARD DIODE WITH ANY PARALLEL RESISTIVE LOAD SUCH AS A LAMP 3 4 WIRE GAUGE SIZING If the power supply is distant from the lock voltage will be lost dropped in the connecting wires so that the Magnalock will not re
