Abstract

An entry sensor, which supports either wireless or wired operation, facilitates installation and is adjustable for gaps between a building entry barrier such as a door or window and the surrounding frame. The sensor, which may be implemented as a single piece design, includes an adjustment mechanism that enables an installer to vary the extension of the sensor to match the actual gap so that the sensor properly secures the building entry when closed. The sensor includes a detector that determines the state of a switch that is responsive to the movement of a plunger mechanism, where the state is indicative whether the building entry barrier is opened or closed, and that may determine whether the sensor is tampered with. The sensor also may facilitate battery replacement that protects the associated circuitry during the replacement.

Claims15

Dependent claims

A sensor device for a building barrier, wherein the building barrier is surrounded by a surrounding frame, the sensor device comprising:

a plunger adapted to engage either the building barrier or the surrounding frame to secure the building barrier when in a closed position and to disengage either the building barrier or the surrounding frame when the building barrier is in an opened position;
a sleeve with at least one engagement tab inserted through a hole in either the surrounding frame or the building barrier;
and
a sensor housing having a discrete increments adjustment mechanism, the adjustment mechanism adapted to adjust a depth of the plunger with respect to the gap between the building barrier and the surrounding frame in discrete increments, wherein the adjustment mechanism comprises:
a slotted rack portion adjustably inserted into the sleeve;
driver features enabling the slotted rack portion to be externally adjusted;
a switch having first and second states indicative of the closed and opened positions of the plunger, respectively;
and
a linkage coupling the plunger to the switch, wherein the linkage moves responsive to movement of the plunger.
