No one detects finer! The infrared presence detector Presence Control PRO IR Quattro HD COM1 AP for indoor use is ideal for medium to large offices, conference and meeting rooms, classrooms, lecture halls, sports facilities, and storage areas. It can be mounted up to 10 meters high, in a surface-mounted version for controlling lights, with 4800 switching zones for the highest detection quality, a true presence area of 64 m², square detection, and mechanically scalable. Live comfortably while saving energy. Enhanced quality of life, safety, and energy savings through intelligent sensor technology from STEINEL. Lights on/off – automatically. Highly innovative sensors respond to movements and light conditions, automatically turning the lights on and off after a set time. The very high-resolution infrared presence detector Presence Control PRO IR Quattro HD COM1 AP features a unique square detection area and COM1 interface in an installation-friendly surface-mounted version. It controls the lighting based on presence and ambient brightness. IR Quattro HD – High Definition – the name says it all: The infrared presence detector has 4 digital pyro sensors with 4800 switching zones for the highest detection quality, even for the smallest movements: 8 x 8 m presence detection, 8 x 8 m radial detection, and 20 x 20 m tangential detection. The rectangular detection and the ability for infinitely adjustable mechanical range settings allow for highly precise planning. Adaptation to the specific usage situation is achieved through additional functions via potentiometers and remote control (IQ mode for automatic adjustment of the after-run time to room usage, pulse mode for controlling a stairwell automation, etc.) as well as through DIP switches (semi/full automation, etc.). The detection range can be expanded through Master/Master or Master/Slave networking. Optional remote controls allow for comfortable installation and operation.
