Intelligent multiple sensor detector for Loop 3000 for early fire detection and reporting in difficult environmental conditions. With a sensor system for measuring carbon monoxide combined with two thermal sensors and a bidirectional isolator in accordance with EN 54-5 and EN 54-17 for the earliest detection of all types of smoldering fires, such as: B. for monitoring cable shafts and sawmills. The PL 3300 COBT continuously monitors the measured variables temperature and CO concentration during normal operation.
- Alarm evaluation with professional CO sensors
- Independent measurement of carbon monoxide with 2 alarm thresholds: pre-alarm: 15 ppm in 15 min, alarm: 30 ppm in 60 min.
- Integrated acoustics for CO pre-alarm and CO alarm
- Highest operational reliability through intelligent linking: thermal and CO sensor via algorithms
- Integrated heat measurement as a differential method and maximum value according to EN 54-5 1A
- Periodically carrying out a sensor test
- Automatic and manual addressing on Loop 3000
- Integrated insulator and T-branch
- Alarm output for controlling a parallel detector display
- Functionalities fully integrated via Loop 3000 protocol
- Presence and absence switching
- Illustration of a temperature profile of the fire alarm system
- Multi-color LED for alarm (red) and fault indication (yellow)
