Multisensor Smoke Swith (smoke/heat differential detection)

- Multisensor for fire detection
- Multisensor smoke switch can apply two principles of fire detection, depending on the situation: scattered light and temperature increase
- Specific algorithms are used to verify the sensor signal and to eliminate fault signals
- Alarm and fault are disposed separately via dry contact
- The multisensor detects early white and black smoke particles as well as temperature changes in the monitored area
- At a rapid temperature increase the sensitivity of smoke detection is raised in addition
- A strong temperature increase of more than 20 K in 5 min causes a thermal alarm
- The degree of pollution of the optical sensor is monitored, partially compensated and displayed via integrated LED display
