The optical smoke detector SD-212SP is designed for automatic detection and signalization of fire. If smoke is detected, the SD-212SP will activate optical and acoustical signalization to alert people in the reach of the detector. It is supplied from external source 10V to 15V DC./AC.
The SD-212SP is designed to detect smoke and is well suited for most fire detection applications. It has also built in siren to warn locally in the case of a fire hazard. The relay jumper offers selectable NO or NC relay output, the memory jumper enables the memory function and also the built in siren can enabled by its jumper. The smoke detector also performs regular auto testing.
A dispersion of infrared light on smoke particles in the optical chamber is used in the detector.
This detection is especially suitable to detect all kinds of visible smokes, for example smoldering wood, paper, fabrics etc.
The detector can be also used to detect smokes from sources creating small amount of smoke but fast increase of the temperature (for example alcohol). For this situations the detector has a built-in temperature sensor, which triggers an alarm when the temperature exceeds 60°C-70°C (it depends on the speed of the temperature increase) |
