Smoke detector BETA SE315EC

BETA CO detectors warn the gas presence in the environment where they are installed with an optical and acoustic signal. They are equipped with an output relay for controlling a solenoid valve for intercepting gas. CO version are calibrated to detect the following concentration: 50 ppm x 70 minutes / 100 ppm x 20 minutes / 300 ppm x 1 minute. This threshold are guaranteed for a maximum period of 5 years. After that period, an optical signal warns to replace the sensor, simply by removing a front plate and using the sensors parts supplied in blister packs.
