Features:
Active extraction sampling, laser detection, sensitivity is 1000 times higher than conventional smoke detector,
capable of detecting invisible smoke, and provide multilevel warning fire formation.
Flexible pipeline arrangement, realizing comprehensive protection of single point and multipoint.
Patented unique structure design, with dust-proof and anti-interference to avoid false alarm.
Strong network function, local network, public network or local area network centralized monitoring is possible
between the detectors.
1000 event logging is convenient to find out the reason of fire alarm and fault.
Equipped with self-learning and self-adaptive ability.
High-efficiency air extracting pump, real-time pipeline airflow monitoring, secondary air filtering.
Complete setting for 4 smoke alarm thresholds
Equipped with 5 programmable relay output.
Application area:
High airflow area, such as telecommunication room, dust-free room, etc.
Large area spacious place, such as warehouse, workshop, exhibition hall, etc.
Low temperature area, such as refrigerated warehouse, etc.
Detection for sheltered place, such as culture/heritage architecture, etc.
Key sector that require early fire detection: such as bank data center, power distribution room of power sector,
airport control tower, etc.
Explosion-proof, strong electromagnetic and intense radiation place, such as arsenal, oil depot, chemical facility,
accelerator, microwave room, television emission tower, etc.
