Hager has launched a new range of occupancy sensors that are easy to install and programme. They combine occupancy sensing with a photocell to switch or dim lighting in response to both movement and natural light levels.
They are available as flush or surface mount, offering standard or digital lighting control. They can also be supplied prewired.
The digital range will auto detect either DSI or DALI and can control up to 24 digital ballasts. Installers can use them with or without the company’s Klik lighting distribution system.
To install, the contractor simply pushes the sensor through the ceiling aperture and reverse springs then hold it in place. This makes it simple to install in a plasterboard as well as a grid ceiling. A sliding cover on the surface of the sensor allows access to its controls without removing it from the ceiling.
You can programme the sensors using a simple intuitive remote control programmer or a potentiometer. The remote control programmer allows different time outs, light levels and other functions to be set using buttons that have descriptive pictograms on. Once the desired settings have been saved you point the remote at the sensor, press the ‘set’ button and the sensor’s LED light flashes to confirm that it has been programmed. You can then save this programme and use it to programme the other sensors to save time.
The end user can override the sensors using conventional wall switches or by a remote control device. The latter can turn the lights on or off and, with digital fittings, dim them and store up to four preset scenes.
Says Steve York, product manager for Hager: “This range of sensors allows contractors to offer sophisticated lighting control using an easy to install and programme system.”
The new Hager sensors allow either presence or absence detection and you can adjust the integral photocell to respond to different light levels, or change it to active or passive mode or turn it off.
With presence detection the sensor turns the lights on when movement is detected and maintains this until there is no further movement after a set period of time, at which point it will switch off the lighting.
With absence detection the sensor detects movement, but requires someone to activate the lighting using a wall switch or remote control. The sensor then maintains the lighting until no presence is detected when it is again turns them off or dims them after a set time out period has elapsed. This option generally saves the most amount of energy.
The photocell can either be set to passive or active. Passive will hold off the lighting if there is sufficient natural light at the time of initial switching and active will control the lights ‘on’ and ‘off’ depending on the available natural light. With digital lighting control the sensor will dim the luminaires up and down in response to changing light levels.
Other functions include; an adjustable time out period of between 2 and 57 minutes using the programming tool and between 2 minutes to 1 hour on the potentiometer, an incremental adjustment of lux level, a walk test function and two programmable memory settings on the programming tool.
