Panic exit devices, commonly referred to as panic bars or crash bars, are an essential feature in public buildings and facilities. These devices are designed to provide a quick and easy exit during emergencies, where safety depends on rapid evacuation. Whether you're a building owner looking to comply with safety codes, or an installer choosing the right panic bar for various applications, understanding the features and types of these devices is critical.
This guide explores the different types of panic bars, their features, and how to select the right one for your needs. We'll also discuss fire-rated vs. non-fire-rated devices to help you make informed decisions.
Choosing the right panic exit device, however, depends on various factors, including the type of door, its function, and whether fire-rated devices are required.
Not all panic bars are created equal. The three most common types of panic exit devices—rim, vertical rod, and mortise devices—serve different purposes and cater to diverse needs. Here's a closer look at each type.
● How It Works
A rim panic bar is mounted on the interior surface of the door with a latch that secures into a strike at the top of the frame. It’s one of the simplest and most commonly used types of exit devices.
● Best Applications
Rim devices are ideal for single doors or paired doors where only one leaf is active. They are also the easiest to install, making them a popular choice for schools, retail stores, and small offices.
● Key Features
- Surface-mounted with minimal installation requirements.
- Provides quick, easy exit during emergencies.
- Works well with doors that don't have extensive hardware.
● How It Works
Vertical rod panic devices use top and bottom latches that secure directly into the ceiling and floor, offering higher security.
● Best Applications
These are commonly used for double doors with both leaves active since they allow greater versatility and coverage. Most vertical rod devices are suitable for wide doorways in high-traffic environments such as hospitals, malls, and auditoriums.
● Key Features
- Enhanced security through dual latching mechanisms.
- Can be concealed to maintain the door's appearance.
- Ideal for doors that require more safety and stability.
● How It Works
A mortise panic bar is embedded into the edge of the door, requiring a pocket (or mortise) to be cut in the door for the locking mechanism.
● Best Applications
Mortise devices are typically used in high-security environments such as financial institutions, government offices, and luxury hotels.
● Key Features
- Offers seamless integration for a sleek look.
- Provides the highest level of security among all types of panic bars.
- Requires professional installation due to the complexity of embedding the mechanism.
Your choice of a panic exit device isn't just about the type—it depends heavily on the door specifications and its intended use.
● Metal Doors
Rim or vertical rod exit devices are the go-to options for metal doors due to their durability and ease of installation.
● Wood Doors
For wood doors, both rim and mortise panic bars work well. Mortise devices are often preferred for doors in high-traffic or high-security areas.
● Single Doors
Rim panic devices provide a simple and effective solution, ideal for smaller single doors in offices or classrooms.
● Double Doors
Vertical rod exit devices work best for double doors where both leaves need to remain operational. Rim devices can also be paired with a latch for some double-door setups.
● Frequent Use
For doors that see heavy traffic, such as main exits, opt for sturdy devices with high-cycle ratings.
● Emergency-Only Use
For doors used strictly as emergency exits, simpler panic bars with fewer moving parts can reduce maintenance needs.
One critical consideration when selecting a panic exit device is whether or not it needs to be fire-rated. Here’s how fire-rated and non-fire-rated devices differ, and when to choose each.
● Definition
Fire-rated devices are designed to remain secure during a fire, preventing the spread of flames and smoke. They are required for fire doors, which are an integral part of fire evacuation systems.
● Key Features
- Built with heat-resistant materials.
- Certified per fire code standards (e.g., UL or NFPA certifications in the U.S.).
● When to Use
If the door leads to stairwells, has access to emergency equipment, or is part of a fire-rated assembly, a fire-rated panic bar is mandatory.
● Definition
Non-fire-rated devices are not designed to block flames and are typically used on doors that serve as standard egress without additional fireproofing requirements.
● Key Features
- May offer more flexibility in design and materials.
- Lower cost compared to fire-rated options.
● When to Use
If the door is for daily use and doesn’t need to meet fire code regulations, non-fire-rated devices are an excellent option.
Selecting the right panic exit device for your property requires careful consideration of your building's layout, the type of doors in use, and the applicable safety codes. Additionally, investing in a high-quality panic bar ensures reliability during emergencies and lowers maintenance costs.
If you're unsure about the best option for your building, consult a professional installer or review local safety codes to ensure full compliance.
Choosing the right panic exit device not only safeguards occupants but also provides peace of mind to building owners and operators. From rim and vertical rod devices to mortise options, there's a solution for every type of door and application.
Whether you're outfitting a school, office, hospital, or retail space, the right panic bar can make all the difference in emergency preparedness. As you weigh your options, prioritize quality, ease of use, and compliance with fire safety regulations to make the best choice for your needs.
