ClareOne Recessed Door/Window Sensor The ClareOne Recessed Door/Window Sensor is a magnetic sensor device designed to fit seamlessly inside a door frame or windowsill and is resistant to magnetic tamper and defeat. A high–powered Microchip delivers exceptional range -no "dead spots" or signal drop-offs. An isolated spiral antenna provides much greater RF surface area to improve range . The antenna is mounted above the board and separated from batteries contributing to the superior RF performance and transmission efficiency. Important Note - Ths product can only be used with the ClareOne Panel (CLR-C1-PNL1). The area must be able to accommodate an 11/16” hole to a depth of 2 1/4” for the sensor and 5/8” for the magnet. Encrypted 433Mhz Technology The ClareOne Recessed Door/Window Sensor features encrypted technology that prevents alarm takeovers. It can be recessed in any door or window frame to communicate a faulted zone to the ClareOne Panel. Tamper Protected Case Features built-in enclosure tamper for both the sensor and case. Universal Mounting Works in wood or steel door frames and effective with both vertical or horizontal mounting placements. Simple Setup Pairs easily and quickly with the ClareOne Panel.
