The Model SD2200 is an advanced Smoke Detector. The SD2200 Smoke Detector photo coupler sensor operates on the law that fluids absorb and refract the light.

Therefore a photo coupler sensor placed inside probe receive the light from transmission sensor when the light is refracted through the smoke particle. The model SD2200 is a new duct smoke detector built-in a photo coupler which has an excellent in sensitivity, stability and for easy for installation in duct smoke monitoring.

The SD2200 can be used in air velocity range of from 0.03 to 25 meter per second and has a photo coupler sensor inside bottom of the probe which is the part of directly contact the smoke. Thus the SD2200 does not require a sampling tube. It also can control fans, blowers.

In addition SD2200 provides auxiliary alarm device such as buzzer, annunciater with alarm signal. The operation alarm signal maintain its status although the smoke is removed from the inside duct and the normal condition is recovered. And the resetting the switch located on the bottom will return to stand-by alarm operation. The SD2200 can be used in 12~24 VDC and designed in order for alarm and supervisory relay contact to connect with such control panel as well. When the sensor failure, power fault, SD2200 gives trouble alarm contact. A green LED indicates power on as normal condition, red LED indicates alarm smoke status.
