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

Supply voltage:

8.5—33V DC

Supply wiring:

2 wires, polarity sensitive

Maximum polarity reversal:

200ms

<20 seconds

Power-up time:

Minimum 'detector active' voltage: 6V

Switch-on surge current at 24V: 95µA

Average quiescent current at 24V: 95µA

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.
