Ventilation Smoke Detector System LRS 03
The ventilation smoke detector system LRS 03 is designed for installation on ventilation ducts with round or rectangular cross-sections for early smoke detection.
The special features are:
- Autonomous system decoupled from BSK
- Long operational readiness due to processor-controlled pollution compensation
- Visible operational and pollution display from the outside
- Easy installation without additional console
- Tool-free testing, maintenance, cleaning
- Simple cleaning of the smoke inlet pipe
- Alarm release button mounted on the housing for quick testing
- Maintenance only once a year
