The latest kind of door switch is actually a part of the hinge and functions on the same reed concept. Its functions are restricted simply because not all types of hinges have got this option.

Additionally they may not be as secure as their header-mounted counterparts. The door has to be opened up even further for the circuit to open up. Security and safety personnel typically would want to see a switch circuit open up when the door is open 4-6 inches wide.

Where by an electrically operated mechanism is really essential to the door itself, electrical power needs to transfer through the frame to the door. Specifiers may achieve this requirement by utilizing either an electric hinge or a power-transfer device.

A electric power door cord is also an alternative solution, however it is often unsightly. These are basically flexible metallic cords by using wiring which affix to the frame on one end and also the door on the other end.

Security Hardware Maintenance Tips

Maintenance Tips

Door-Hardware Maintenance Includes Lubrication, Adjustment

Most door-hardware components require maintenance at some point, due to general wear and tear from regular use. Among the most common types of repairs for these components are lubrication, adjustment, alignment and weather sealing.

  • Lubrication is required once every six months to a year for all
  • security hardware, depending on the type of door and its level of use. Hinges and door closers should get a few drops of penetrating oil at the top so it runs down into the wearing surface between the pin and the housing. Security lock mechanisms that need lubricant should get a shot of dry graphite from a spout-type bottle. In addition to simply providing lubrication for door hardware, this step prevents freezing in cold weather. A good time to schedule lubrication is just before cold weather starts. Technicians should not lubricate electronic locks because graphite is an insulator and will interfere with current flow through contacts.
  • Regarding security hardware adjustments, the two parts of a door that most often require attention are hinges and closers. During lubrication, technicians should check hinge screws for tightness. In time, wood door frames dry out and screw holes open up, so the screw continues turning. When this happens, your security hardware technicians should fill the hole with appropriate hardening filler, redrill the hole and replace the screw — or place a screw insert in the hole and replace the screw.
  • Closers operate either pneumatically using air or hydraulically using oil. Over time, the door begins to bang against the stop or does not close all the way. Technicians can correct this security hardware problem by adjusting the screw on the cylinder. This security hardware step regulates the stroke so the door just closes against the stop without banging or leaving a gap. Closers come with installation and adjusting instructions and parts lists. Managers should file these and give them to the tradesperson when making the preventive maintenance assignment, a move that will save technicians a great deal of time at the job site trying to figure out how the mechanism works. This job is probably not going to be done very often, so the operation of each different type of closer or lock will be only vaguely familiar to the tradesperson, even if the same person does it every year.
