Simple energy saving from new Klik
sensors
Hager launch new Klik OS light sensitive occupancy sensor that promises large energy savings for simple on/off lighting control solutions.
The new sensor has the option of both presence detection or, for greater savings, just absence detection In its presence detection mode the sensor combines switching in response to movement with light levels

Easy fit fuse carriers from Hager
Hager introduce new range of easy to fit fuse carriers for the protection and control of circuits against overloads and short circuits.
When the ambient light levels drop below a preset level the sensor will switch the lights on.
If it then detects no movement after a preset period it will switch the lights off.
This time delay to switch off can be set between 5 and 35 minutes.

If you select absence detection only mode, then the sensor will detect movement but will not switch on the lights when people enter the area.
Occupants need to switch the lighting on using a wall or other retractive switch.
Once the lights are turned on, the sensor will turn them off after detecting no movement for a preset time.
Says Mike Biggs, product manager for Klik: "By selecting the absence detection only function on an occupancy sensor, individuals have to make a decision to turn on the lights.
The sensor will then turn off the lights after no movement has been detected for a preset time.
In practice people tend to forget to turn off the light so this option maximises the potential energy savings for simple switchstart solutions.
"For some commercial buildings lighting accounts for more than 50% of electrical consumption so any energy savings are significant.
Measures such as this can help you comply with Part L and reduce energy consumption".
The new sensor further reduces costs by managing the artificial lighting in response to natural daylight levels.
It can operate in one of three modes; as just an occupancy sensor or it can manage the light levels in either passive or active mode.
In the passive light management mode, the sensor will stop the lights switching on if the lux levels are above a set point, but then it will not switch them off during occupancy.
Active management has the same functionality but will also switch off the lights if the photocell detects that there is enough natural light to achieve the desired lux levels.
Says Biggs: "These new sensors can bring much of the sophistication of a digital lighting control solution to simple switchstart installations".
You can use Klik OS for both new lighting installations and refurbishment.
It is programmed using a handheld RF programmer and has a walk test mode.
End users have a handheld remote RF control, which they can use to override the sensor during the period of occupancy.
The sensor is compatible with Hagers Klik LDS distribution boxes, which allows planning and installation of simple, local group lighting control systems.
Klik LDS can run a single or two separate lighting circuits thanks to its dual switching, so either one or two Klik OS may be used. Request a free brochure from Hager ...
