XPander Optical Smoke Detector
Where to Use Optical Detectors
XPander optical detectors are recommended for use as general purpose smoke detectors for early warning of fire in most
installations.
XPander optical detectors operate on the well established light scatter principle. The optical design of the XPander optical
detector allows it to respond to a wide spectrum of fires.
The detector is calibrated so that XPander is highly reliable in detecting fires but has enhanced immunity to false alarms.
The stability of the detector in terms of high reliability and low false alarm rate is further increased by the use of algorithms
to decide when the detector should change to the alarm state. This removes the likelihood of a detector producing an alarm
as a result of smoke from smoking materials or from another non
-
fire source.
Detector Operating Principles
Photo
-
electric detection of light scattered by smoke particles over a wide range of angles. The optical arrangement
comprises an infrared 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.
This product is tested and approved to the AS 7240
-
7 standard.
