A noisy telephone entry panel or a stuck door strike usually occurs due to a bad ground wire or an incorrect power supply. We replace these with clean, low-voltage wiring and set the battery voltage properly so the Door King intercom works reliably. Storms can damage boards if there’s no surge suppression, so we check that as well. No more complaints about the front access control system.

Alpha Doors and Security offers the expertise and parts needed to install your access control system.
