Understanding Push Bar Doors
A push bar door, commonly found in commercial buildings, is a door that is opened by pushing a horizontal bar that unlatches the door, allowing it to be pushed open. They are also known as panic bars, crash bars, or push bars, and are designed for easy exit during emergencies, complying with safety regulations.
Why Locking Push Bar Doors is Important
In general, push bar doors are designed to allow free egress from the inside. However, it’s equally important to be able to lock these doors to prevent unauthorized entry from the outside or to secure the premises after hours.
Step-by-Step Instructions to Lock a Push Bar Door
Locking a push bar door can vary depending on the hardware and locking mechanism in place. Below are general steps that can be adapted to your particular door hardware.
Step 1: Identify Your Locking Mechanism
First, determine the type of locking mechanism that your push bar door uses. Common types include a rim lock, a vertical rod lock, or a mortise lock. The locking mechanism may involve a key, a combination lock, or an electronic access control system.
Step 2: Engaging the Lock with a Key
If your push bar door has a keyed lock, use the key to engage the lock. Typically, you would insert the key into the cylinder on the exterior side of the door and turn it to lock or unlock the door. Some push bar doors can also be locked from the inside by turning a knob or key.
Step 3: Using a Hex Key or Allen Wrench
Some push bar doors can be locked or unlocked using a hex key or Allen wrench. Insert the wrench into the appropriate hole or slot on the push bar itself or the door’s edge and turn it to engage or disengage the locking mechanism.
Step 4: Securing Doors with Vertical Rods
Doors equipped with vertical rods sometimes have a latch at the top or bottom that can be manually moved to secure the door. This requires physical access to the latch, which may involve opening a panel or using a special tool.
Step 5: Electronic Access Controls
For doors with electronic locks, you may need to use a code, card, fob, or biometric data to lock or unlock the door. These systems may provide options for scheduling automatic locking and unlocking based on time of day.
Step 6: Test the Door
After engaging the locking mechanism, test the door from both the outside and the inside to ensure that it is properly secured and that egress is still possible from the inside.
Tips for Secure Locking
– Always follow manufacturer’s instructions and local building codes when operating and locking push bar doors.
– Do not compromise the ability for individuals to safely exit through the door in case of an emergency.
– Maintain your door and locking mechanism properly to ensure they function correctly when needed.
– Periodically check the lock’s functionality and integrity.
– Train staff on how to operate and lock the push bar doors.
Conclusion
Locking a push bar door is a straightforward process that ensures the security of a property while still complying with safety regulations. Always consult the manufacturer’s guide specific to your door’s hardware for precise instructions. If in doubt, seek the help of a professional locksmith or door hardware specialist to assist with the installation or operation of the locking mechanism.
