  If the maglock isn't locking and the internal alarm isn't sounding, here's what you can check: * Make sure the power supply is providing the correct voltage, both at the supply and at the DE5300. * Verify the power supply output voltage is 24VDC. * Ensure the power wiring has continuity from the power supply to the Module. * Confirm that the power supply has the correct polarity by verifying the proper color code is used.

Why does the Von Duprin Control Unit release delay start immediately when arming, causing the maglock to lock and then release after 15 seconds, and the internal DE5300 alarm to turn ON?
- R
  Ricky ShawAug 17, 2025
  If the release delay starts immediately when arming, the maglock locks and then releases after 15 seconds, and the internal DE5300 alarm is ON, the issue could be: * The push pad is not returning to the full extended position. Pull the push pad out fully to see if this fixes the problem. Also, check for dirt and rubbing around the push pad area. * The Device Wiring Cable (2 position plug) is disconnected. Plug in the Device Wiring Cable 2 position plug. * The REX wiring/connector is defective. Check for broken wiring from the Device Wiring Cable 2 position plug to the REX switch under the Push Pad. * The REX switch is defective. Check the REX switch is closed when the Push Pad is fully extended; if it's still open, replace the switch.

- A
  Anna CampbellAug 27, 2025
  If the maglock remains unlocked after a power outage and power is restored (with the Key Switch in the Armed position), it might be because the DE5300 is not self-arming after the outage. Check if DE5300 onboard switch #5 (Armed Power Up) is set to OFF.
