<p>A remote control door entry system, which may be installed in a door jamb/frame, in the center frame post of a door assembly that has a side ligh t glass unit, or centered in the edge of the stationary door of a double door arrangement. The entry system is used for controlling a lock having a spring latch bolt (274) and a dead latch bolt (276). A slide bolt (44) engages and compresses the dead latch bolt (276) in a locked position (Fig. 3a). In an intermediate position the dead latch bolt (276) is released by the slide bol t (44), and in a further unlocked position another slide bolt (4) engages and compresses both the spring latch bolt (274) and the dead latch bolt (276).</ SDOAB></p> |
