Acrylonitrile Butadiene Styrene (ABS)
ABS is a type of plastic that has been made to withstand impact and/or heat. It is considered superior for its hardness, toughness and electrical insulation properties.
Delayed-Off Time
Delayed-Off Time is the elapsed time light will be turned off after movement is no longer detected. The Delayed-Off timer is adjustable to reduce false deactivation of light and to suit different environment. For example, a shorter Delayed-Off Time may be preferred in corridors to save energy while a longer Delayed-Off Time may be preferred in offices to prevent lights from turning off while working.
Detection Seqence Logic (DSL)
Detection Sequence Logic is a method developed by SUREN to reduce false activation of light. A microprocessor in the occupancy sensor is programmed to turn on light only when major body motion is detected as a person enters a room or an area. The occupancy sensor will then keep the light on even as minor body movement is detected.
Heating, Ventilation, Air-Conditioning (HVAC)
Heating, ventilation, air-conditioning devices including exhaust fans and variable-air-volume controls of HVAC systems.
High Definition Infrared (HDIR) SUREN's high definition infrared sensor is made of its proprietary and patented 8-element pyros. It has higher detection resolution than the 2-element PIR sensor and could detect smaller body movement of people working in a stationary position.
Optical View Pattern
Optical view pattern divides an area that an occupancy sensor monitors into smaller sections thereby increasing detection resolution.
Passive Infrared (PIR)
PIR detection technology is used in SUREN's occupancy sensors to detect movement based upon the heat radiated from the body.
Pyroelectric Element (Pyro)
Infrared sensing element that is typically paired to recognize movement based upon the difference of heat energy detected. Heat radiated by a stationary object would be cancelled out by the pyroelectric pair.
Sunset Sensor (Photoelectric Sensor)
A sunset sensor inhibits light from turning on if there is sufficient natural light in the area thus saving energy. The sunset sensor is adjustable to suit different environment. For example, less light may be required in corridors compared to offices.
