ABSTRACT:
RELATED APPLICATIONS
The present invention is related to copending application entitled “Door with Integrated Smoke Detector and Hold Open”, Ser. No. 09/033,383, now U.S. Pat. No. 6,049,287, which is filed simultaneously herewith and hereby incorporated by reference herein.
BACKGROUND OF THE INVENTION
The present invention relates generally to an entry door for a building and, more specifically, to a building door having electrical components associated therewith for sensing and reacting to emergency conditions and having the capability to communicate with other doors as part of a door network.
Installing doors into buildings under construction typically requires the assistance of various tradesmen. For example, for one opening, tradesmen such as carpenters, painters, glaziers, electricians and drywallers are required to complete the installation of a door. Other tradesmen may also be used for the installation of a door. The number of tradesmen increases when the door has security or other speciality items incorporated near the door opening.
Once a door is installed, the interaction of the various components must be verified. In many instances, one of the many skilled trades must return to the opening to adjust or replace various components that are not functioning properly.
One of the various types of components associated with a door opening is a hold open. Hold opens are mounted to a wall or door closer to hold a door in the open position. The door may be held open by a cam and motor device or electromechanical means. Smoke detectors and/or fire detectors are also commonly coupled near an opening of a building. U.S. Pat. No. 5,072,973 teaches a device having a smoke detector and hold open using a motor and cam. Upon detection of smoke, the smoke detector releases the hold open to allow the door to close.
One problem with such a device is that the functionality of the components within the door must be checked after the installation of the door. In some circumstances, either the door or hold open must be adjusted requiring the expensive use of one or several skilled trades.
SUMMARY OF THE INVENTION
It is therefore one object of the invention to provide a less costly door system. To reduce the numbers of components installed on site certain components are preinstalled and tested in a factory environment. Such components, for example, may include a hold open and a smoke detection device within the door.
In one aspect of the invention, a door has a first outer face having an opening therein and a second outer face spaced a predetermined distance apart from the first outer face. A void is located between the first and second outer face and is sized to receive at least a portion of an integrated door unit. A wiring harness is located between said first and second outer faces. The wiring harness has a connector coupled thereto. The wiring harness is coupled to the integrated door unit. A sensor is coupled to the integrated door unit.
In a further aspect of the invention, a single or plurality of communication lines couple together a plurality of integrated door units each associated with a respective door. Each of the integrated door units having a memory storing an address, and a data map. The integrated door units form output data words using the address and the data map.
In another aspect of the invention, a plurality of communication lines couple a plurality of integrated door units together. The integrated door unit forms data output words. Each of the integrated door units have an address associated therewith. Each of the integrated door units have a transceiver and a door controller coupled to the transceiver. The transceiver receives data output words and directs data output words having a corresponding address to its associated door controller. The controller generates a response to the data output word.
One advantage of the invention is that a central controller is not required. Each integrated door unit is coupled to a network through which each integrated door unit can communicate to each other in a predetermined format.
