Panic Hardware – Learn the basics


Damage from panic attacks is more common than you think. Damage may result from the lack of maintenance of such equipment and / or the installation of fake components or components.

As a door and hardware specialist witness and forensic adviser, I kept many cases where the installed panic attacks were the source and cause of some bodily injury. As a practitioner and installer, I installed and organized thousands of panic devices and experienced, evaluated and solved the problems that arise with these special hardware.

Three Most Common Problems with Panic Hardware Door Damage (1) Incorrect Installation (2) Low Maintenance (3) Appropriate secondary locks are installed.

Panic drive is a door element designed to move quickly and unhindered from the door. The panic drive is typically located on the corridor doors where the fire hazard separates and provides separate areas for the smoke, fire or heat control of a commercial building, hotel or hospital. Most of the high traffic or high density buildings, such as cinemas, large arena complexes or restaurants, are usually found on the exit doors. Panic attacks relate to almost every location where rapid evacuation from the building can be the difference between the lives and death of the passengers (life security).

The most important aspect of all panic equipment is that there is no need for special knowledge for their use. Simply pushes a bar, a bar or another activator, the locking mechanism retracts and presses the door. These types of devices operate differently from a typical door lock, as they are designed to allow exit without any key or any rotating motion. Usually it is equipped to travel to the building or to the exit of the controlled corridor. These devices are presumably suitable for the use of disabled (ADA-compatible) or suitable persons.

Over the years, panic attacks have changed to improve the ease-of-use of ADA's compliance and improve general security for the population. Early panic equipment was originally created using a horizontal tube or flat band. A pair of arms that rotates on both sides of the tube or rod on the base plates allows the panic to operate and activates the locking retraction mechanism. While these devices work properly, numerous injuries have arisen due to the panic attack of the door. The poorly maintained and incorrectly replaced hardware styles cause more errors in many cases when I held myself as a door hardware expert.

These early devices are still visible in many facilities across the country, and many of them work well and are properly maintained. If all of this Panic Device has been properly configured, securely attached and securely attached to the door, the device will still be in control of most life-safety checks.

The modern panic attack is commonly referred to as "Crash-Bar". This piece of hardware usually consists of a flat integrated component that retracts a locking mechanism. Like the older style tool that uses the pipeline or lane, the newest stitch pin is more easily pressed and usually resistant to oblique problems and operates less moving elements on the outside of the device.

There are several options for the outside of the door with a parallel device (pull side). In one case, the panic tool can only be used as an exit. There is usually no return through this door. Doors from some doors also have a key lock cylinder on the outside of the door that retracts the locking mechanism when the key is rotated. This allows the authorized user to open the door from the outside of the opening. Another option is to install a movable handle or handle on the outer casing with a key lock cylinder. For both components, it is possible to reentry, either by moving the lever or the button, or by pressing a button if necessary. For some more sophisticated installations, a card reader or push-button access code reader can be used to retract the lock mechanism. There are several major security options available for use. In all cases, in case of external access the above-mentioned reentry options function is basically the same; Each of them uses to retract some of the panic locking mechanisms in some way, enabling the door pull side to enter.

Another common feature of panic devices is "slipping" (open mode or disabling device). This feature can be used when a panic device is in an area that needs to be dropped, for example, in a restaurant or vaulted door, where the fire code requires that concessions remain open during normal working hours.

In a crossroads, panic devices are often paired. These devices, together with special nameplated fire doors and other hardware, are installed to try to stop the fire hazard and dispose of it. This kind of panic structure relies on vertical bars to keep the doors closed when the high pressure of the fire builds behind the door. The vertical rods can be raised or completely reflected inside the door. In some applications, an upper and a lower vertical bars are connected to a latch mechanism that is connected to a door frame and floor header with a striker plate or cup. For other facilities, the top bar is currently required. The fitting of these devices typically includes a lever or button on the pull side of the door to allow for rebirth. As described above, there are many opportunities to enter a panic device area from the pull side.

Depending on the installation conditions, panic devices can be installed or paired individually. These are fire rated or can not be categorized. They can operate as one-way exit devices or allow reinstallation using different hardware and components that allow access to the door pull side. Some panic attacks are electronically activated, delayed circuits are integrated, and can integrate into sophisticated supervised alarm and access systems. The most basic tool is a stand-alone piece of hardware that only delivers exit.

If the Panic Network is improperly installed or damaged by misuse or poor maintenance, the efficiency of the intended operation can not be guaranteed. Improperly installed or incorrectly installed panic equipment may fail due to mechanical damage. Deviating the latching components may cause the panic failure. In this case, the panic attacks do not adequately provide the door to protect the smoke, fire, or other unfavorable conditions protected by the cross-corridor hole. Alternatively, improperly installed devices may be defective if they are not released to allow unlimited exit within a given area and possibly into a dangerous zone.

If incorrect maintenance is performed, parts for refurbishing or replacing are often overlooked, replaced, or removed from a device. In some cases, projections from the appropriate replacement parts cause bodily injury, such as severe cuts, bruising and rarely the amputation of the body parts. The above conditions have been observed several times, where larger screws or screws have been installed instead of the required part. Cover plates and lock covers were damaged and sharp, and often remove internal components that could cause injury.

Any secondary lock that is added to a panic hardware door can completely disarm the hardware. If the door is blocked by a mechanical barrier or chain, the door will not open by the panic attack. In some areas where theft is a cause for concern, loud alarm panes have been installed with delay function. Storage owners or managers find that the alarm is not audible or can not be detected soon there are chained or placed obstacles in front of this door to try to prevent theft through these exits. This hindrance or limitation of the exit is life-threatening and often does not meet firefighters. Most, if not all commercial buildings are regularly evaluated to meet safety and fire safety standards. If a shop owner or manager chooses to close or close the required exit point, the store may be directly responsible for endangering public safety.

While thorough scrutiny of on-site conditions is prudent in every facility, many facilities choose not to fund these studies and maintenance is often postponed. This improper deferred maintenance has led to several injuries that have created laws that could easily have been avoided. When using the public as a building, it is of utmost importance that competent and trained hardware professionals are communicated and employed to ensure property ownership so that all systems and hardware work at the highest standards. The "penny wise and foolish ruthless" reveals a lot of real estate owners.
