ENVIRONMENTAL
PERFORMANCE
Orbis optical detectors operate over a
broad range of voltages at extremes of
temperature. Thus the operating voltage
is 8.5V to 33V at –40° to +70°C, a unique
achievement for a conventional smoke
detector.

IP rating to EN 60529: 1992*: 23D
Electromagnetic Compatibility: The detector meets the requirements of EN 61 000-6-3
*The IP rating is not a requirement of EN 54 since smoke detectors have to be open in order
to function. An IP rating is therefore not as significant as with other electrical products.

CONVENTIONAL DETECTORS
TECHNICAL DATA
Photo-electric detection of light scattered by smoke
particles over a wide range of angles. The optical
arrangement comprises an infra-red emitter with a prism
and a photo-diode at 90° to the light beam with a wide
field of view. The detector's microprocessor uses algorithms
to process the sensor readings.
