In the past office blocks and other large buildings have been known for using huge amounts of electricity. Lighting is often left on in empty rooms, corridors and stairways for long periods of time. In large towns and cities it is not uncommon to see businesses with their lights switched on all night. This is largly due to forgetfulness and can prove to be a very expensive oversight. Modern technology can easily overcome this problem and there are big savings to be made. (continued below)
In our luminaire ancillary section are a range of electronic switches, controls and related accessories. They allow you complete control over all the lighting on the inside and outside of a building. They are designed to save energy by switching off when not required and only re-activating when light is needed. They can help with security by switching on lights when prowlers least expect it and possibly preventing burglaries. However, it's the convenience gained by using these products that is the main benefit; they are simply fit and forget.
The PIR is the most common detector in use today switching luminaires to light anything from driveways to industrial states. The remote photocell sensor is also popular for the automatic switching of dusk to dawn lighting. Other controls include PIR occupancy switches that monitor areas for people and turn off lighting when none are present. Occupancy switches with automatic dimming will adjust internal lighting according to external natural light levels. There are also radio remote controls available as well as a range of luminaire ancillary items.
Most of the lighting sensors are easy to install because they are wired directly into existing circuits. They were designed to retrofit or are equally suitable for new installations. Some passive infra red motion sensors for outdoor security lighting may require additional wiring. The amount of extra wiring will depend on the distance between the sensor and the light. In most cases sensors can be positioned close to light fittings so this will mean minimal additional work.
