The constant fear of something happening in the building while you are still inside is something that many of us experience. We can never totally remove the possibility of catastrophic incidents such as a fire happening. Fortunately, many buildings employ rim exit devices on their emergency doors to allow for more immediate evacuation.
Every establishment should install exit devices so people can easily exit in case of emergencies. While these devices may not be used often, they still help in safely securing the way in which people leave the premises.
What Are Rim Exit Devices?
Among all panic exit hardware that exists, rim exit devices are the most popular and commonly used. This type of panic exit device allows people to easily push out of swinging doors for exit. It has an exit device trim or lever.
The rim device can be used on a single door or double doors. The end of the panic device has a latch bolt that latches onto the surface of the rim (the door frame).
Rim panic devices are easy to install since all door hardware is mounted on the surface. If you want an exterior pull plate or lever, you can simply bore a hole to attach it.
This kind of heavy-duty panic device can only be operated from the inside by pushing a crossbar or push rail. A rim device is a good option for convenient installation, and no re-adjustments are needed after successful installation.
Rim exit devices are rated in two ways: panic hardware or fire-rated panic hardware.
A rim exit device should not be confused with a mortise exit device. While the two may look similar, a mortise exit device is only applicable for doors with a mortise lock. This door lock is great for aesthetic interiors but can be more difficult and expensive to install.
Benefits of Installing Rim Exit Devices
Exit devices, regardless of their type, have one main purpose: safety. Doors with exit devices serve as the safest option for exit in case of emergencies.
And since people may start to panic when things start to go awry, the installation of easy-to-push exit devices becomes crucial for survival.
Exit devices also have simple components that very rarely malfunction. With this in mind, one can guarantee that it won’t disappoint to deliver during an emergency.
The addition of rim exit devices, or any panic devices for that matter, also gives you a good discount on insurance premiums. Insurance companies give better rates to properties with advanced emergency preparation protocols in place.
Additionally, an exit device tightens security when placed on exit-only doors. It makes sure that the door remains inaccessible from the outside and no strangers can get in.
Exit devices can further supplement security systems, especially in the case of an alarmed exit device. The alarm will sound when an exit device is used, which alerts the security team that something is happening in real time.
Two Case Studies for Rim Exit Devices
Establishments, school campuses, government offices, and other similar facilities and institutions see a lot of pedestrian traffic. So, securing reliable fire exit hardware becomes a primary concern.
Here are some case studies to prove the significance of rim exit devices for these places.
Winds West Elementary School Implements ASSA ABLOY Door Security Solutions
Winds West Elementary School, located in the heart of Tornado Alley, experiences about 11 tornadoes per year. With this natural phenomenon occurring frequently, the need for a reliable exit door device is highly prioritized.
The newly constructed wing employed FM8700 exit devices from Sargent, along with other heavy-duty hinges and locks.
The extremely sturdy door assembly was chosen specifically for its strength and ability to resist the damaging effects of a tornado. They are also used in safe rooms as well as in emergency shelters that follow the protocols and guidelines of the Federal Emergency Management Agency (FEMA).
Tarrant County College Makes Use of Von Duprin Exit Devices
Texas’ 6th largest college, Tarrant County College, boosted its security features by upgrading its access control and security systems. Among the upgrades they did on their campus was the installation of Von Duprin 99 Series QEL electrified exit devices.
The Von Duprin Series rim exit device features a latch bolt design. There are four bolts mounted for better security and durability.
The exit devices have QEL (quiet exit latch) capability. This means that the panic bar operates quietly, which is very beneficial for major areas within the campus, such as the auditorium, the classrooms, and the library.
Criteria for Choosing Rim Exit Devices
Ordinary door knobs do not provide the necessary security and safety elements needed for emergencies. For this reason, panic devices should be installed at exit points for a more organized evacuation procedure.
Choosing rim exit devices, however, isn’t a walk in the park, and many things should be considered.
Door Design
Doors come in various types. A rim exit device only works for outswinging doors. You can install this particular exit device in both single and double doors.
Size of the Door
Exit devices should be in accordance with the size of the door. You cannot install a short bar onto a large door because it defeats the purpose, and vice versa.
Measure the size of the door where you intend to install the rim device. Then, scout for rim devices that cater to that particular size and door thickness.
Materials
Heavy-duty materials like stainless steel or aluminum mostly make up rim device construction. The durability of the materials used indicates how dependable the device will be.
Certifications
Certifications are proof that exit devices do the work they are designed to do. Certification bodies have set standards that brands have to comply with to pass. These standards determine how well rim exit devices work.
ANSI-grade, UL-listed, and ADA-compliant labels mean you can trust the product.
Rim Exit Devices for Safe Exit
Exit devices may not be used as often as entry gates, but they do have a special role in ensuring safety in cases of emergencies. The installation of a rim exit device provides people with greater peace of mind, knowing they can safely exit the vicinity with ease.
