Here's a common maglock problem that leaves many access control techs scratching their heads.
Your customer asks you to fix a problem with this door:
Everything works great, except one side of the maglock seems to hold the door closed a split second longer than it should - it almost seems 'sticky' - a user has to push on it hard to open it, with noticeable 'pop' and maybe even some door vibration. Over time, the door could bend and not lock correctly, or someone might even injure themselves trying to force it open.
After you inspect the maglock, power supplies, and access settings, everything seems correct. The lock wiring is in good shape, there is even an MOV/diode installed at the lock, and the controller is opening the lock contacts as it should. At a glance, everything looks the same as another door nearby, except that door works perfectly.
The customer thinks the $1800 maglock must be bad. Your company installed the lock 11 months ago, so the customer is asking for a warranty replacement.
