Switching
The presence detectors can be operated as a master in individual switching. Several push buttons can connected to one control input. Illuminated push buttons can only be used with neutral conductor connection.
Single unit operation
In individual switching, the presence detector as master detects presence and brightness and controls lighting.
The circular detection area of theRonda presence detector covers a large detection area and permits a good room coverage with many applications. Note that seated and moving persons can be detected in differently-sized areas. The recommended installation height is 2.0 m – 6.0 m. As installation height increases, the sensitivity of the presence detector decreases. Walking motions are necessary from installation heights of 3.5 m, and the detection areas of several detectors should overlap in the marginal zones. The detection range is reduced as the temperature increases.
Seated persons
The details relate to smallest movements at table height (approx. 0.8 m).
Moving persons
At installation heights between 5 and 10 m, the extent and distance between the active and passive zones increase.
The presence detector measures artificial light and daylight that is reflected directly below the detector. The light measurement area maps a rectangle of about 2 x 3.5 m at table height. The installation location is a reference point for the lighting level. Direct light influences the light measurement. Avoid placing floor lamps or suspended lighting directly below the detector. If the brightness measurement is deactivated, the light channel only switches depending on the presence (brightness switching value set to „lux on“ via potentiometer or set to „measurement off“ via the remote control).
Suitable lamps
The presence detector is designed for the operation of fluorescent lamps, compact fluorescent lamps, halogen/incandescent lamps and LEDs. The maximum number of switchable lights is restricted due to the high inrush current levels of the EBs and LED drivers. The use of an external contactor helps with large loads. All switched loads must be properly suppressed.
Flush-mounted installation
The flush-mount installation of the detector is done using a standard UP (flush-mount) installation socket Size 1.
Ceiling installation
A ceiling installation unit is available for a simplified ceiling installation of the detector (see accessories). This ensures strain relief and contact protection at the same time. The installation diameter is 72 mm (drill diameter 73 mm).
Surface-mount installation
A suitable surface-mount frame is available for surface installation (see accessories).
