Hydrogen, Carbon Monoxide, And Smoke And Heat Combined Fire Detection Device
ESF-EI9106EX
Features
1.Employs non-polar dual-bus technology for simple installation and maintenance;
2.Low power consumption design with low monitoring and alarm current;
3.Features automatic zero-drift compensation and temperature compensation technologies to maintain constant alarm sensitivity;
4.Independent sensor module design allows for calibration-free replacement in the field;
5.Automatic sensor fault detection effectively prevents missed alarms;
6.Real-time monitoring and alarm of combustible gas concentration in industrial environments, enabling real-time transmission of on-site gas concentration information.
