Honeywell V-Plex PIR motion sensor, 50FT W/ ANTI-MASK The next generation of V-Plex PIR motion sensors, based on the award-winning IS3000 series, features simple installation, superior detection, and minimal false alarms. The sensors are compatible with Honeywell control panels that support V-Plex devices, using two-wire loop technology to save you time and money.V-Plex? Patented Polling Loop TechnologyBy using two wires instead of four, V-Plex offers significant advantages over peer-to-peer wiring or the conventional four-wire multiplex.For example, since each sensor can be installed using only two wires for both power and data, you spend less money on wiring. V-Plex devices also draw minimal amounts of current, therefore requiring fewer auxiliary power supplies.Designed for Faster InstallationThe IS3050A-SN mounting screw pre-drill collars and retention features, removable connector blocks for easy access, and patented flashlight walk test make installation fast, reducing labor costs and enabling you to move on to the next job quicker.
