How to Install and Maintain Panic Exit Devices？

Ensuring the safety and quick evacuation of occupants during emergencies is crucial in any building. A panic exit device, often referred to as a crash bar, serves as a lifesaving mechanism designed to enable fast and unimpeded exit during emergencies. It is essential for commercial buildings, schools, hospitals, and other establishments where mass evacuation might occur. In this article, we will discuss how to install and maintain panic exit devices to ensure they function correctly when needed the most.

Terms Explanation

Crash Bar

Also known as a panic bar or bump bar, a crash bar is a door opening mechanism designed for emergency exits. It consists of a spring-loaded metal bar fixed horizontally across the door. Pushing the bar unlatches the door, allowing swift egress.

Panic Exit Device

A general term for devices, including crash bars, installed on exit doors to facilitate quick escape during emergencies. These devices often comply with modern fire and safety regulations.

Task Step Guide

Step 1: Understand the Building Code Requirements

Before installing a panic exit device, it's crucial to familiarize yourself with local building codes and fire regulations. These codes dictate the type, placement, and installation methods for panic exit devices. Obtain copies of the relevant codes from your local fire department or government office.

Step 2: Select the Appropriate Panic Exit Device

Panic exit devices come in various styles and sizes:

• Touch Bar Exit Devices: These are sleek and require minimal pressure to operate.

• Cross Bar Exit Devices: Traditional style, typically a horizontal bar spanning the width of the door.

• Rim Exit Devices: Mounted on the surface of the door.

• Mortise Exit Devices: Recessed inside the door and provide a cleaner appearance.

Choose a device that suits the door type and usage:

Type of Device	Use Case
Touch Bar	High-traffic areas
Cross Bar	Older buildings with traditional aesthetics
Rim Exit Device	Surface-mounted convenience
Mortise Exit Device	Modern buildings desiring a clean look

Step 3: Gather Necessary Tools and Materials

For installing a panic exit device, you will need:

• Drill and various bits

• Screwdrivers

• Measuring tape

• Pencil

• Level

• Safety glasses

• Panic exit device kit (includes the bar, latches, screws)

  
  

Step 4: Measure and Mark the Installation Points

• Measure the Door: Measure the door width and height to find the center.

• Mark the Center Line: Using a pencil and level, mark the center line where the panic device will be installed.

• Align the Template: Most panic exit devices come with a template to help in marking the positions of screws and holes. Align the template on the center line and mark the holes accordingly.

  
  

Step 5: Drill Holes

Drill holes in the marked positions for the screws and any other components that need to be fixed to the door. Use appropriate drill bits for the door material (wood, metal, etc.).

Step 6: Attach the Panic Exit Device

Follow these steps:

• Fix the Main Mechanism: Attach the main bar mechanism horizontally on the door, aligning it with the drilled holes. Secure it using screws.

• Install the Latches: Fix the latches on the door frame where they will secure the door when closed.

• Check Alignment: Ensure the installed bar aligns perfectly with the latches and operates smoothly.

  
  

Step 7: Test the Device

Open and close the door several times, pressing the bar to ensure it releases the latches quickly and efficiently. The operation should be smooth and require minimal pressure.

Step 8: Maintain the Panic Exit Device

• Regular Inspections: Inspect the device at least twice a year for any wear and tear.

• Lubricate Moving Parts: Use appropriate lubricants to keep moving parts functioning well.

• Check Alignment: Ensure that the bar and latches are always aligned correctly.

• Test Regularly: Conduct routine tests to verify the device's functionality during emergencies.

  
  

Tips and Reminders

• Ensure your panic exit device complies with all local fire and safety regulations.

• Engage a qualified professional if you are uncertain about installation procedures.

• Keep emergency routes clear and ensure the devices are always accessible.

• Regular maintenance is crucial for reliable operation during emergencies.

• Consider installing alarms with exit devices to alert security personnel during unauthorized use.

  
  

Conclusion

Installing and maintaining a panic exit device is vital for the safety of building occupants. By following the steps outlined—understanding building codes, choosing the right device, installing it correctly, and performing regular maintenance—you can ensure a safe and swift evacuation during emergencies. Always prioritize adherence to safety regulations and consider professional advice when in doubt. With proper installation and maintenance, panic exit devices become invaluable assets in safeguarding lives.
