ON/OFF [

MICROWAVE A transmitter sends out continuous waves of radiation that These detectors can be more robust than a PIR but travel through walls and can cause unplanned detection. PHOTOCELL The sensor reacts to natural ambient light and will turn on $ remains on until the light increases to a second pre set light level, at which the light will switch off. This is useful when limited illumination is required for safety or security. SEPARATE CONTROL WIRE Used to control most commercial applications where the power usage is greater. Allows the transmission of 1-10 ‚ ! < ^! [^ WIRELESS TRANSMISSION Used to transmit a digital signal and doesn’t require a ! suffer interference and are limited in range particularly where walls and metal objects exist. Examples of these include RF (radio frequency) and Zigbee which is an example standard that allows meshing to increase range and availability.

ON/OFF TIMED Switches the lights on for a pre-programmed time and are often used in communal access corridors and staircases. DIMMABLE Switches allow adjustment of the lighting, often adjusted by rotation or the length of time the switch is held down. NON-DIMMABLE $  can therefore only be switched on/off. DIMMABLE $ it receives a signal from a controller. Examples include phase dimming and 1-10V dimming. PIR §_ ^ … for changes in the heat pattern. The sensor detects the change in radiation and turn on the light.
