Siemens OH720 Multi-Sensor Detector c/w Dustcap (Requires Base) for the detection of flaming fires caused by the combustion of liquid and solid matters, as well as smouldering fires. For reliable fire detection in environments with deceptive phenomena.
Works according to the scattered-light principle with an optical forward scattering sensor. An additional heat sensor increases the fire detector’s immunity to deceptive phenomena. Selectable detection behaviour by different parameter sets. Immunity against transient false alarm causes.
The base must be ordered separately.
| Key Features |
|---|
| > Point detector > 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 > Additional heat sensor increases the point detector's immunity to deceptive phenomena > Selectable detection behaviour thanks to two parameter sets – Parameter set 1: 'Robust', Parameter set 2: 'Sensitive' > Immunity to false alarms > Detects flaming fires of solid and liquid substances as well as of smouldering fires > Reliable fire detection in an environment with deceptive phenomena |
