A vertical rod panic bar replacement involves removing and installing a exit device that secures a door from top to bottom. Vertical rod panic bars are typically on double doors or doors without a center post, and they engage at both the top and bottom of the door frame.
Here’s an overview of the steps involved in replacing a vertical rod panic bar:
Preparation and Safety
- Verify the compatibility of the new exit device with the door dimensions.
- Ensure the door is in good condition and does not have structural issues.
- Gather all necessary tools: screwdriver, drill, measuring tape, etc.
Remove the Old Exit Device
- Unfasten the screws securing the existing exit device bar to the door.
- Detach the top and bottom rods carefully as they connect to the frame’s latches.
- Remove any mounting hardware from the door and frame.
Install the New Push Bar
- Measure and mark the placement for the new push bar, ensuring it aligns with the existing latches in the frame.
- Attach the main body of the exit device to the door using screws, making sure it sits securely.
- Install the top and bottom rods, adjusting them to reach the latches accurately.
Testing
- Ensure the push bar functions smoothly by pushing on it to release the latches.
- Confirm that the top and bottom latches engage and disengage when the bar is pressed.
Final Adjustments
- Adjust the rod lengths or positioning if the door does not open or close smoothly.
- Tighten all screws and ensure that the exit device operates without resistance.
WHY IS IT IMPORTANT A ROD IN A PANIC BAR SYSTEM?
The rods in a vertical rod panic bar system are crucial for ensuring adequate door access control security and quick egress in emergencies. Here are the main reasons why they’re essential:
TOP-TO-BOTTOM DOOR SECURITY
The rods connect the exit device to the top and bottom of the door frame, securing the door at both points. This dual-point locking mechanism makes the door harder to force open than a single latch, enhancing security.
EVEN FORCE DISTRIBUTION
When someone pushes the exit device, the rods distribute the force to both the top and bottom latches. This balanced distribution prevents undue stress on any part of the door or frame, reducing the risk of mechanical failure.
INCREASED STABILITY FOR DOUBLE DOORS
Vertical rod systems are ideal for double doors without a center post, where each door panel needs to be secured independently. The rods ensure that both door leaves are stable and secure until the exit device is pressed.
QUICK AND SAFE EGRESS IN EMERGENCIES
In an emergency, people can exit quickly by pushing the push bar, which immediately disengages the top and bottom latches via the rods. This setup allows doors to open with minimal effort, which is essential for fast evacuations.
COMPLIANCE WITH FIRE AND SAFETY CODES
Many safety codes require reliable exit devices, especially in public or commercial buildings. Vertical rods help ensure doors comply with safety standards by providing a secure, easily operable exit.
Overall, the rods in a panic bar system balance security and accessibility, ensuring that doors stay locked when needed but can open swiftly in emergencies.
PANIC BAR PARTS WITH ROD
A vertical rod panic bar system consists of several essential parts, each vital in its function and effectiveness. Here’s a breakdown of the main components typically found in a rod-based push bar system:
Push Bar
The main horizontal bar is on the door. The design is for opening the door when pushed and disengaging the locking mechanisms to allow safe and quick egress. The push bar is connected to the rods and latch mechanisms to ensure smooth operation.
Vertical Rods (Top and Bottom)
These rods run from the push bar to the top and bottom of the door. When the panic bar is pressed, both rods retract, releasing the latches and opening the door.
- Top Rod: Connects the push bar to the top latch mechanism.
- Bottom Rod: This rod extends from the push bar to the bottom latch mechanism, securing the door at the bottom.
Top Latch Mechanism
This latch connects to the top rod at the top of the door frame. When the push bar is pressed, the top rod retracts, disengaging the latch and opening the door.
Bottom Latch Mechanism
This latch connects to the top rod at the top of the door frame. When the push bar is pressed, the top rod retracts, disengaging the latch and opening the door.
Strike Plates
- Top Strike Plate: Mounted on the frame where the top latch engages. It is a secure point for the top rod to latch onto when the door is locked.
- Bottom Strike Plate: This plate is placed on the floor or threshold to secure the bottom rod. It receives the latch, holding the door access control in place until the bar is pushed.
Center Case or Housing
This is the central part where the push bar and rods connect. The housing contains internal mechanisms that transfer the force from the push bar to both the top and bottom rods, ensuring simultaneous disengagement of the latches.
End Caps
These protective covers are located at each end of the exit device. They protect the internal mechanisms from dust, debris, or damage and give the device a finished look.
Dogging Mechanism (Optional)
Some exite devices have a dogging mechanism that allows the bar to be “dogged down,” keeping the latch retracted for easier access during hours when locking isn’t necessary. This feature is often a hex key or lever used to hold the bar in a depressed position.
Each vertical rod panic bar system part is essential for maintaining security or enabling a quick exit. Together, they make the exit device reliable and easy to use, critical for emergency safety.
