TECHNICAL DATA
All data is supplied subject to change without notice.
Specifications are given at 23°C and 50% relative humidity unless otherwise stated.
DETECTOR OPERATING PRINCIPLES
Principle of detection:
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. The heat sensing element increases the
sensitivity of the detector as the temperature rises.
Sampling frequency:
Once every 4 seconds
ELECTRICAL

ENVIRONMENTAL
Temperature:
Operating and storage temperature
Humidity:
0% to 98% relative humidity (no condensation)
Wind speed:
Unaffected by wind
Atmospheric pressure:
Insensitive to pressure
IP rating to EN 60529: 1992*: 23D
Electromagnetic Compatibility: The detector meets the requirements of EN 61 000-6-3
for emissions and BS EN50 130-4 for susceptibility.
*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.
