The HBA LightHAWK LHIRS0I digital infrared occupancy sensor is ideal for smaller spaces where you will not have obstructions of line-of-sight due to switch location, room orientation or furniture placement. The auto mode is self-adjustable based on occupancy from 4 to 30 minutes, and the fixed mode can be set for 4, 8, 15, and 30 minutes. It features a dual-element pyrometer and 12-element cylindrical Impact-resistant infrared (IR) RhinoTuff lens. For indoor use only, the switch operates in temperatures of 32 to 104-Degree Fahrenheit (0 to minus 40-Degree Celsius), and relative humidity of less than 95-percent, non-condensing. The switch plate has an ivory finish with dimensions of 4.2 by 1.8 by 2.1-Inch. The sensor's cover range is 180-Degree, up to 1000-Square Feet. The HBA LightHAWK LHIRS0I digital infrared occupancy sensor without manual override is covered by a five year limited manufacturer warranty, and is sold one item per package. The LightHawk passive infrared wall switch occupancy sensor represents the state-of-the-art in sensor technology by utilizing passive infrared (PIR) technology for unequaled occupancy detection and false trip immunity. The sensor features HBA's patented IntellADAPT technology that continuously analyzes its environment and self-adapts, eliminating the need for manual sensitivity and timer adjustments during installation as well as over the life of the product. IntellADAPT provides true maintenance free "Install and forget" operation. With automatic ON/OFF mode and a built-in photo sensor for automatic daylight harvesting, the LightHawk passive infrared wall switch occupancy sensor is simply the most capable wall switch occupancy sensor available in the marketplace today. Hubbell Building Automation is a strong proponent of innovative, integrated and simple energy saving lighting controls.
