A complete line of wireless accessories—including sensors, repeaters, and motion detectors, for use with the recently introduced Sensaphone 2800 remote monitor and alarm notification system—is now available. The Sensaphone 2800 is a stand-alone unit requiring no monthly fees. It provides four hard-wired universal inputs and can work with up to four of the new wireless sensors to help protect equipment and facilities by alerting owners, managers, lab technicians, building supervisors, and others to changes in critical environmental conditions. The wireless sensors have a range of up to 300 feet from the base unit, and an added repeater can extend the distance up to an additional 4,000 feet. Installation for each features plug-and-play simplicity, with the host unit automatically detecting and configuring new sensors. Each accessory includes three AAA batteries with a three-year life expectancy and AC adapters. Available wireless accessories for the Sensaphone 2800 include a temperature sensor, a dry contact sensor, a power failure sensor, a humidity sensor, a 4-20 mA sensor, a motion detector, a spot water detection sensor, a zone water detection sensor and a repeater.
