Expand the coverage of your Napco Prima Security System with the Napco Prima Wireless Window/Door Transmitter. The wireless door/window sensor is used to monitor a door or window and alert you to changes in status or when the sensor is being tampered with. The sensor consists of two components, a magnet and sensor, which trigger an alert that is sent to a connected Prima receiver to indicate a change in position status. The sensor includes 1-way encryption to protect it from unauthorized intrusions or hacking, and will also notify you if the sensor is tampered with. Two CR2032 lithium coin cell batteries ensure long-lasting performance and minimizes the hassle of regular battery replacements.
Napco's crystal-control Prima wireless products have been proven by an independent testing laboratory to outperform competitive products, with long-range RF reliability, as much as 50% higher than other brands. Prima's uncommon crystal-control precision and omnidirectional circuitry, ensures the wireless/hardwire systems you provide your customers will dependably deliver the security and trouble-free, peace-of-mind they deserve for many years to come. All Prima panels and receivers seamlessly support the full line of Prima transmitters and virtually all panels, keypads, receivers and peripherals are compatible with each other and work the same, model to model.
