Automatic Operator Actuators

The 2007 edition of ANSI/BHMA A156.19 - American National Standard for Power Assist and Low Energy Power Operated Doors requires low energy operators to be initiated by a "knowing act", which is described as "consciously initiating the powered opening of a low-energy door using acceptable methods, including: wall- or jamb-mounted contact switches such as push plates; fixed non-contact switches; the action of manual opening (pushing or pulling) a door; and controlled access devices such as keypads, card readers, and key switches."

Door Opening Force

Door opening force is the measurement of how many pounds of force are required to open a door.  The requirements for door opening force are found in the Americans with Disabilities Act Accessibility Guidelines (ADAAG), ICC/ANSI A117.1 Standard on Accessible and Usable Buildings and Facilities, and the Massachusetts Architectural Access Board requirements (521 CMR).

Time-Out Lock

One of our customers sent me this photo last week.  It was found on a psychiatric facility and to operate it, a staff member must be present and holding the bolt projected via the lever.  I did my best to track down a manufacturer with no luck.  It's possible that it was made in a machine shop or that it is no longer available, but my first thought when I saw it was that I need to buy 3 for my kids' rooms and then find 3 suckers to stand there holding the bolts projected.  ;-)

Tactile Warning

Tactile warning is an abrasive or knurled strip on a lever handle to indicate that the door leads to a hazardous area such as a boiler room, mechanical room, or loading dock.  This requirement is no longer included in the Americans with Disabilities Act Accessibility Guidelines (ADAAG) or in ICC/ANSI A117.1, but it is a requirement of the Massachusetts Architectural Access Board (521 CMR):

Electrical Power Transfer (EPT)

An EPT is an electrical power transfer, which is used to transfer wires from the door frame to the edge of the door.  It is used when there is a door-mounted piece of electrified hardware which requires power and/or sends a signal to a remote location.  The security consultants that I have worked with all prefer the EPT over electric hinges or door loops, which perform the same function.  It is also preferred over an electric hinge by most installers, because the EPT can be installed when the wiring connections are made, rather than being installed by the carpenter, removed for wiring, and reinstalled, getting mangled in the process.  The EPT is concealed when the door is closed (the door loop is exposed and prone to abuse) and it can accommodate larger gauge wires than an electric hinge.

Door Gap Gauge

The instructors in my Fire Door Assembly Inspector (FDAI) class showed us a really handy gauge to measure clearances around fire rated doors, and since I'm going to do my first *official* inspection tomorrow I tracked one down.  It can easily and accurately measure 1/16", 1/8", 3/16", 1/4", and 3/8" gaps, and a 3/4" undercut.  For only $18.95, you can be the proud owner of your own Door Gap Gauge by shopping online at doorgapgauge.com.

Panic Hardware on Electrical Rooms

Beginning with the 2002 edition, the National Electric Code (NFPA 70) requires that certain types of electric rooms have doors that open in the direction of egress and are "equipped with panic bars, pressure plates, or other devices that are normally latched but open under simple pressure."  According to an engineer I spoke with at the National Fire Protection Association, the releasing device could be a hospital latch or paddle-type release, but the fact that the words "panic bar" are used in the Code has prompted many code officials to require panic hardware.
