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. The heat sensing element increases the
sensitivity of the detector as the temperature rises.
