troubleshooting electronic door locks

Remove the wires from the two terminals which read zero volts. If the electric strike operates properly with the door held open, the lockset may be pre-loading or binding the keeper of the electric strike. Please note that the HES 8300 fire rated strike is NFP80 compliant and does not require a hole to be cut in the frame. One of the great benefits of the UnLatch is its motor driven mechanism. Overload current through the PolySwitch trips it so that it clamps the current down to roughly 100mA. 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). Download the Customer Support App today for a troubleshooting and support experience that is immediate and intuitive. An electronic lock (or electric lock) is a locking device which operates by means of electric current. Are HES electric strikes polarity sensitive? These days a firearm for home defense is a better idea than ever. 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. You can use the following illustrations to identify you lock:Typical Cylindrical Lock (Use the UnLatch with this type of lock), Typical Mortise Lock (Use the Mortise UnLatch with this type of lock). We are considering using the UnLatch lock for an upcoming project with an access control system. It is a very reliable system, but subject to wear and tear as any other part in a vehicle. There are three potential causes that can produce a failure of the buttons to seat. Second, a problem can arise with the Magnalock. I have an existing electric strike and transformer. The Premis lock is design to overcome pressure resistance on its bolt as result from weather stripping and warped door as result of climate and/or structural variations. Please check with your designated project authority for guidance. What do I need to mount it on the inside (in-swing side) of the door? Check the strike and magnet face to see if something is interfering with a flat fit. Tighten the hinge screws and then try adjusting the strike plate by loosening its screws and shifting it slightly. The microprocessor will accept this sequence and interpret it as code 1-2 in memory slot 45. Yes, simply use a 2004M ElectroLynx Adapter. PolySwitches look like capacitors. Yes, mounting the lock on the jam will not change the functionality of the Magnalock. The power consumption for each strike is listed on the front page of the installation intructions and on the label on the back of the strike. Be sure you're not waiting more than 5 seconds between hitting keys as if you are, the entry will be ignored. Perform the door handing process in the Installation Guide. Later it will be noticed that the door is opening on 1-2 as this is such a simple sequence that it will be entered. What are signs that my power supply isn’t providing sufficient amperage? Representatives are available8 a.m. - 7:30 p.m. ESTMonday through Friday. Liquid error (blog-sidebar line 37): include usage is not allowed in this context . Is there anyway to set off an alarm should main power fail? Read them again carefully. Some HES can use A/C power for intermittent operation. If all of the LEDs are out use a meter to check between F1 and F2 on the power distribution board if you see system voltage here then your fire alarm has disconnected the system.Second, if the LED on the outside of the box is out check the AC input, if there is no AC voltage present you have found your problem.Third, if AC voltage is present check the AC input fuse. I have a requirement that states that I must automatically unlock all my doors upon the activation of the fire alarm system. An inexpensive plug-in D/C power supply would suffice, such as Securitron part # PSP-12 or PSP-24. Next, check to see if the keeper is returning fully. Yes, electric strikes with old-style, white connectors are compatible with most Quik-Wire version accessories with a simple field modification. When this is confirmed note that the UnLatch will never operate unless the springlatch plunger is pushed in by the springlatch. First, check the access control equipment it may be faulty or have been installed improperly. Do you offer anything for our CCTV installations? Is a shotgun a good choice? Set it to DC for PolySwitches #2 and #3. Depending on your lock, you may have to wait 10 to 20 minutes before attempting to enter your code again. This is almost always due to use of a switching power supply. The hole in the door is misaligned. 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. Note: If your vehicle has electronic door locks, you will need to remove the door lock cluster panel from the door panel. *Some old-style accessories, such as the old-style 2001: Plug-in Bridge Rectifier and the old-style 2003: MOV are not field-modifiable because there are no leads when the connectors are removed. We offer a series of "Z" brackets for this requirement. are properly connected. Go into your Jetta and play around with the power lock switches. The UnLatch requires 3-3/8" Long, 1-3/8" Wide, 2" Deep while the Mortise UnLatch requires 3-3/8" Long, 1-7/8" Wide, 2" Deep. Sign up for promos & updates from Liberty Safe. If PolySwitch #1 has tripped, visually inspect the four large diodes on the board to see if a loose wire has fallen on them to create a short circuit. Check that the switch, key pad, etc., meet the voltage requirements for the system. If it works properly under this test, you need to adjust the door so the pressure is eliminated. The following chart will show you the allowable distance based upon operating voltage and wire size. We now need to figure out the size of our battery back up. If the strike is mounted too rigidly, proper alignment can't occur and the lock won't hold. A third option with a double door (assuming that there is no center mullion) could be to use one magnet mounted in the middle of the jam with a split strike option. Is there any way that we can mount the narrow DK-26 keypad to the single gang electrical box without leaving an exposed opening along both sides of the keypad? If the actual gap is significantly greater than this, you have found the problem. It is suggested you change your battery with a good quality alkaline battery, like Duracell or Energizer, every six to 12 months to ensure smooth operation of your electronic safe lock. We have an existing DK-26 entry system with the keypad on the exterior of the door. Plug the black connector at the other end of the 2007M pigtail into the 2001M: Bridge Rectifier and set voltage/finish wiring as directed in the instructions included with the accessory. A tripped PolySwitch acts as a high impedance resistor so you will read several volts across the PolySwitch leads. HES does not manufacture an intrinsically safe/explosion proof strike. Can I use HES electric strikes for continuous duty? It is important that for us to confirm that the lock is actually locked. First, press the back up release on the back of the bar if the door does not release the there is a fault in the systems general wiring. Learn about this problem, why it occurs, and how to fix it. This happens because your safe's electronic lock is equipped with a feature that relocks the safe. But this is only a temporary condition that might seem like a minor inconvenience. DK-26PBK (narrow black - indoor/outdoor), DK-26PSS (narrow stainless steel - indoor/outdoor) or DK-16P (single gang - indoor). For further questions, please call Customer Support at 800-626-7590. Checking between red and black with a meter you should see system voltage.Fourth, if the back up button works, you have tried adjusting the sensitivity and you have good voltage at the six pin connector check the antenna wire and make sure it is connected to the bar via the Phillips head mounting screw also check to make sure that the screw is not stripped. This problem can be corrected by cleaning the surfaces of the magnet and strike or establishing proper play in the strike mounting. For further questions, please call Customer Support at 800-626-7590. The lock is not holding properly (I can pull or tug it open). Is there an intrinsically safe/explosion proof strike available? When the UnLatch can't generate enough torque to release the latch, it automatically shuts down but then operates the next time it is triggered. The latch status output will change state when the springlatch plunger is pushed in. If the LED flashes once quickly the lock is drawing to much current or you power supply is under rated for the system. Ambient temperature should be between -31°F to 151°F. )Finally, the unit could have experienced motor failure or other internal electronic failure. We're here to help! Two terminals, however, will read about zero volts. We need to have battery back up. Check for full isolation between the strike and the door frame (when the door is secured) with an Ohmmeter. The electric strike does not operate properly when the door is closed. If terminals SRC and HCD are connected, the Hard code will be disabled. If a strike failure has occurred during the warranty period it should be returned to a distributor for a replacement. A rusty Magnalock will still function but at reduced holding force. It supplies 10 amps of 24vac power. If the buttons do not seat, the lock will not hold. 0.01 micro Farad capacitors to the supply one between positive and earth ground and one between negative and earth ground. Finally, verify that there is no debris interfering wiht any of the mechanics. It must be powered with the correct input voltage and checked to see if it draws the specified current. To circumvent this, use a pencil or other similar object to lightly push in the springlatch plunger and then close the trigger wire to +V and you will see the UnLatch plungers move. Using a multimeter, verify that the input voltage is within the recommended limits (+-10%). Note: drop is higher on smaller gauge. Both the Magnalock core and strike plate are plated and sealed following a military specification. Your total current draw will be 840mA. First, what is my total load or current draw, and second how long (maximum length of time) do I need to maintain the load on battery. DK-26 and DK-16 Specific: Unit won't accept programming. Just verify that there is sufficient space in the jam to accept the body of the lock. For those requirements we offer the BACS-24-10. If the product is installed in a heavily corrosive atmosphere, such as near the ocean, it will eventually rust even with non abrasive cleaning. Once the plating has been removed, it cannot be restored in the field, so the lock will have to be periodically cleaned and coated with oil or other rust inhibitor. Including videos, step-by-step tutorials, guides, and more. Each PolySwitch protects against a particular problem and you need to know how to determine if the PolySwitch has tripped and how to correct the problem and reset the PolySwitch. Contact your distributor for price and availability.If the strike is still under warranty it can be returned to the distributor from which is was purchased for replacement. You can depend on these locks to keep your guns and valuables secure in your safe. DK-26 and DK-16 Specific: Keys do not operate but I hear a beep every five seconds. Remove the old-style, white connector from the electric strike and connect the free wire-ends to the wire-ends of the 2007M pigtail connector. Door Lock Doesn’t Latch Properly When a door latch doesn’t click into position, it usually means the latch and the strike plate are out of alignment. Having trouble with an installation? Note that the core is separated into 3 sections from left to right. This can arise through an unnoticed programming error. It protects against an internal short on the board. If the problem occurs on initial installation, usually it's caused by misunderstanding the programming instructions. I am having difficulty figuring our which lock is best for my various applications. First, check for voltage at the lock if voltage is present and the door is not locked then the lock is the problem.Second, if you do not have voltage at the lock check the sensitivity adjustment potentiometer on the back of the board turning the POT counter-clockwise will decrease the sensitivity and the bar may begin to function.Third, if adjusting the sensitivity does not work try removing the red wire of the harness from positive DC if the door does not lock check for voltage between the white and black wire of the harness if you have no voltage then an upstream switch is more likely the problem.Fourth, check the surrounding area for anything that might generate an RF field such as neon signs or loss prevention gates disconnect the device and see if the bar begins working properly, if it does then the addition of a 22,000 micro Henry inductor in-line between the board and the bar should solve the problem. What type of power do HES electric strikes use? Monitoring generates improper indication (LBM, LBSM). Pay particular attention to the keypad white wire going into terminal WHT. If the LED does not go on then the code is not being accepted and you need to re-program the system. Solenoids can reach around 140 degrees F.  Note: if the electric strike becomes too hot to touch, it is likely that there is too much voltage getting to the strike and this will cause damage to the solenoid if left unchecked. If it does then the system is functioning normally and you need to check the lock and lock wiring. ; Read More If they are, temporarily disconnect the keypad and attempt to reset PolySwitch #3 by de-powering the board for 5 seconds. Additional outputs can be added with CCB-8A slave boards. DK-11 Specific: Entering the code does not unlock the door. Can I use HES electric strikes in double door applications? Call the factory. 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. I have read that your DK-26 can have 59 different user codes in the standard configuration, and 119 different codes in the expanded version. If you run into any issues with the electronic safe lock on your new Liberty Safe, do not hesitate to contact your local dealer for advice. The power supply requirements will vary depending on the strike and the quantity and type of auxiliary devices that are going to be used. Email options ideal for after-hours support. 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.
