Đầu báo khói quang SIEMENS OP720
– Smoke detector consisting of Point detector and Detector dust cap to protect the point detector during the construction phase.
– Functions according to the scattered light principle with one sensor, optical forward scattering.
– Opto-electronic measuring chamber which obstructs disruptive extraneous light but provides excellent detection of smoke particles.
– Selectable detection behavior thanks to two parameter sets
+ Parameter set 1: Standard;
+ Parameter set 2: Sensitive.
– Use for detection of smoke-generating flaming fires and smoldering fires.
