Smoke snesor
Advantage:
①. Advanced ultra-thin smoke extraction chamber and excellent signal/noise ratio
②. Compatible with 500 series products
③. Good resistance to solid airflow, up to 20 m/s wind speed without the false alarm (wind resistance)
④. The two-bus system, polarity, then the decimal address dip switch set in the bottom of the detector
⑤. With sealed dustproof, insect-proof, and anti-back pressure characteristics
⑥. With special shielding measures, strong interference performance
⑦. Address dialing code directly in decimal, easy to operate
⑧. Double LED display，it can be observed from 360 degrees in any direction
⑨. The blinking status of the LED is controlled by the controller, which can make the detector blink or not in the monitoring state and light up constantly in the alarm state
⑩. With sensitivity test hole and magnet test, easy to test and check on site
⑪. Sensitivity can be tested on-site, but also the controller remote testing
⑫. Electronic circuit integration, easy to replace and maintain on-site

The introduction of Smoke snesor
The railway smoke sensor is intelligent sensors that utilize a state-of-the-art thermistor sensing circuit for fast response. These sensors are designed to provide open area protection with50 foot spacing capab-ility as approved by UL 521. fixed temperature alarm. it is a high temperature sensor with 190°F fixed temperature alarm. Two LEDs on each sensor light to provide 360° visibility of the sensor indication. The LEDs can be latched ON by code comma nd from the panel for an alarm indication. The LEDs can also be unlatched to the normal condition by code command. Remote LED annunciator capability is available as an optional accessory. The sensor require compatible addressable communications to function properly.
Functions
The detector is a modern technology of ultra-thin intelligent analog photoelectric smoke detector, built-in special processing chip, the sensitivity of the sensor can be set according to the different environments in the detector with software.
The smoke concentration change of the detector is displayed continuously on the controller in analog quantity, and the sensor has good protection against insects and dirt and anti-electromagnetic radiation interference.
The system can automatically compensate for changes in various non-fire factors such as dust, temperature, and humidity, thus ensuring the stability of sensitivity and fundamentally reducing the false alarm rate of the detector.
