Abstract: There is provided a method of arranging a security alarm system on a window/door and framing. The system includes an object and a sensor which is capable of detecting the object within a predetermined range. The method includes positioning a first of the sensor and object on a first of the window/door and framing. The method includes opening the window/door to a threshold distance which facilitates ventilation and inhibits an intruder from passing through the window/door. The method includes positioning a second of the sensor and object along a second of the window/door and framing such that the sensor is able to detect the object as the window/door is opened up to but not past the threshold distance. There is also provided in combination, a window/door, framing extending about the window/door and a security alarm system coupled to the window/door and framing in the manner described above.

Abstract: There is provided a method of installing a magnetic proximity sensor including positioning the magnetic field sensor in a desired location and positioning a magnet in a desired location relative to the magnetic field sensor, with an indicator of the sensor continuing to be turned on during the predetermined period of time when the magnetic field generated by the magnet is sensed by the magnetic field sensor, and being turned off during the predetermined period of time when the magnetic field generated by the magnet is not sensed by the magnetic field sensor. The indicator light thus assists in determining proper relative positioning of the magnet and the magnetic field sensor. If after the predetermined period of time more time is needed to install the magnetic proximity sensor, the method includes initiates another predetermined period of time by removing and replacing a lid of the magnetic proximity sensor.

Abstract: A proximity sensor comprises a magnet which generates a magnetic field and a magnetic field sensor. The magnetic field sensor includes a radio and an antenna which can transmit an output signal on a plurality of output frequencies. A microprocessor is programmed with a plurality of data protocols. Each of the output frequencies operates on at least one of the data protocols. There is a dip switch which is actuated to provide a code to the microprocessor. A data protocol is implemented by the microprocessor based on the code. There is a MEMS oscillator programmed to a discrete frequency based on the data protocol implemented by the microprocessor. The MEMS oscillator provides the discrete frequency to the radio. The radio is provided with single phase-locked loop which generates the output signal based on the discrete frequency. The single phase-locked loop may be a ×32 multiplier.

Abstract: A compact wireless security sensor having a magnetically operated plunger switch. The compact nature of the sensor of the present invention makes it ideal for being substantially concealing into a door frame or window as part of a wireless security system. The sensor unit includes a housing having an inner end, an outer end, and a magnet positioned within a moveable plunger, and an antenna, preferably a flexible wire antenna. The housing further contains a sensor switch, a microprocessor with a PCB, a wireless transmitter, such as an RF transmitter, and a power source, such as a small coin cell battery, for emitting signals to a master station or controller when the plunger switch is depressed and activates the internal sensor switch.

Abstract: A compact size wireless sensor for sensing a change of state that includes a sensor switch, a microprocessor, a wireless transmitter, a timer (e.g., a low power clock circuit), an antenna, and a coin cell battery power source. The coin cell battery, which is positioned in a stacking arrangement with the microprocessor, switch, and transmitter, allows the sensor to be of a significantly reduced size. Moreover, to provide long life despite a small battery, the microprocessor is run in a standby mode in which the microprocessor draws little power unless it actually samples the state of the sensor switch during select intervals. Various electronic components individually, or in combination, assist in the sampling (monitoring mode) in such a way as to reduce current consumption from the power source. The compact size makes the sensor ideally applicable for wireless intrusion systems embedded within hollow frames of windows and doors.
