Siemens Siemens OH720-CN dot-type composite smoke temperature sensing fire detector

1. OH720-CN product introduction:

●  Meet the national standards GB4715-2005 "Point-type Fire Detector" and GB4716-2005 "Point-type Fire Detector"
●  The emitter irradiates smoke particles from different angles, and the scattered light is transmitted to the receiving tube to generate a measurable electrical signal.At the same time, the temperature sensor can detect smokeless fire.
●  Early fire detection can be carried out regardless of whether there is smoke (black smoke or white smoke) or no smoke at all
●  Strong ability to resist environmental factors, including dust, fiber, insects, moisture, extreme high or low temperatures, electromagnetic interference, corrosive gases, vibration, non-fire smoke, etc.
●  internal integrated short circuit isolator
●  communicate with the controller through the D-BUS loop
●  The product label comes with tearable coded stickers for easy engineering debugging
●  Soft address addressing mode
