Solid Build Quality

360° motion activated Occupancy and Light control sensor. The design is based on Passive infrared motion sensors technology and when implemented will significantly reduce the energy consumption for the end user. The sensor operates by detecting the movement of the infrared heat emitted from the body of an occupant in a given area of coverage or field of view. When it detects the presence of people, it will automatically turns on the light in the given area so the occupants will have adequate light to perform their work. The lights will be automatically turned OFF when the presence of occupants are no longer detected or when the combination of light (both external or natural light plus the installed lighting) exceeds the preset light level for the area provided the area is still occupied. By automatically turning ON and turning OFF lights the user will be able to save significant amount of energy (up to 60% depends on the usage pattern). 

Three Way Sensor

It detects your single minor movement

This setting controls the minimum amount of movement required for the sensor to detect whether a given area is occupied (human movement is used for detection) and turn ON the lights. Sensors are shipped with this setting set to the most sensitive position. The customer can manually change this setting on the sensor using a remote control unit.


The Lux Level setting of the sensor controls the switching ON and OFF or dimming level of artificial lighting. The customer can manually change this setting on the sensor using a remote control unit.

Time Delay

This is the duration that the sensor maintains the lights (or any other load connected to it) in the ON condition after the last occupancy is detected. Sensors are shipped with this parameter set at 5 min. The customer can manually change this setting using a remote control from 30sec to 30min.

Remote Control

Sensors can be remotely controlled by an Infrared (IR) remote control. This enables better control of the sensor�s parameters during installation. Sensor provides a visual cue to indicate the setting being changed and also value of the settings.

Setting Storage

When a remote control is used to change any setting, the setting is automatically saved into the sensors permanent memory. This helps the sensor to retain the setting even after a power loss The setting can be overridden by entering the override mode on the remote control there by reverting back to hardware based settings..

Visual Cue

Sensors provide visual cue during configuration of settings. The RGB LED light up in different colors depending on the current value of the setting being changed.

Three Way Option

Three way sensors are a combination of occupancy and vacancy sensors. The load can be turned ON either automatically by occupancy detection or manually by means of an external switch. Turning off is always automatic upon vacancy as detected based on a user settable time delay. This mode is typically used in conjunction with two/three way switches in stairs.

On-Demand Mode

This mode is used to provide on-demand lighting. User can select three different mode of the sensor. ‘Always OFF’ mode indicated by red color LED indication; ‘Always ON’ mode indicated by green color LED indication; ‘Auto’ mode indicated by yellow color LED indication
