Electric Strike and Nightlatch Replacement in Belfast

A contractor recently raised a job with Delta Security Systems for the replacement of an electric strike and nightlatch at a Belfast property. The existing hardware had reached the end of its serviceable life and needed professional replacement to maintain secure access control.

The Job

Electric strikes and nightlatches work together to provide controlled entry to buildings. The electric strike is mounted in the door frame and releases when triggered by an access control system—whether that's a fob reader, keypad, or intercom release. The nightlatch on the door itself provides the locking mechanism that engages with the strike.

When either component fails, the entire access system is compromised. In this case, both required replacement to restore reliable operation.

Our Installation

Our engineer attended the Belfast property and completed:

  • Removal of the old electric strike from the door frame
  • Installation of a new CDVI electric strike with proper alignment
  • Replacement of the worn nightlatch with a new unit
  • Testing of the complete access control circuit to verify operation
  • Final adjustments to ensure smooth door operation

The installation was completed efficiently, leaving the access system fully operational.

Why Quality Hardware Matters

Electric strikes and nightlatches are subjected to constant use in busy properties. Choosing quality components from reputable manufacturers like CDVI ensures:

  • Reliable operation – Consistent performance under heavy use
  • Durability – Built to withstand thousands of cycles
  • Compatibility – Works seamlessly with existing access control systems
  • Security – Proper engagement and holding force
