Beyond Human and Hardware Issues: The Other Problems
In some cases, door findings may result from environmental or scheduling factors beyond human control. These "other" types of findings are more difficult to anticipate but can be managed with the proper procedures.
Below are some other problems that a checker should know and look out for.
Signage
The numbering should be legible and properly affixed. Clear and concise signage ensures that the correct doors are used in the right circumstances.
Card Reader
The card reader should function properly, be free of damage, and be securely mounted. Inspect for signs of tampering, wear, or malfunction, and verify that it reads cards accurately and effectively communicates with the door lock system.
Glass Panels
The glass panels should be free of cracks, chips, or signs of wear. Look for vulnerabilities such as gaps and entry points.
Pressure Changes
The door should be capable of handling fluctuations in air pressure without affecting its operation. Pressure imbalances from the HVAC system can cause doors to slam shut, stay ajar, or become difficult to close; check for proper sealing, door alignment, and pressure relief mechanisms to prevent damage or malfunction.
Access Scheduling
Confirm that the access control scheduling system is programmed correctly to allow or restrict entry based on the designated schedules.
Natural Occurrence
External environmental factors or physical phenomena can happen naturally and affect a door's functionality or its locking mechanism. These factors include:
- Humidity or Moisture: Doors may expand or swell due to increased humidity or moisture in the air, causing the door to misalign with the lock.
- Temperature Changes: Extreme heat or cold can cause materials like metal or wood to expand or contract, leading to misalignment between the door and its locking mechanism.
- Settling of a Building: Over time, buildings may naturally settle, causing the door frame to shift and the door to fall out of proper alignment.
- Wind or Weather Exposure: Strong winds or constant exposure to elements like rain, snow, or extreme heat can wear down or warp the door and frame, leading to a faulty lock.
- Corrosion or Rust: Natural aging or exposure to moisture can cause metal locks or hinges to rust or corrode, making it difficult for a door to lock properly.
- Pest/Bugs: Pests, like wasps or bees, may create nests inside the door frame, obstructing the locking mechanism.
