Carbon Monoxide And Smoke/Heat Combined Fire Detection Device
ESF-EI9103
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.Utilizes temperature compensation technology, minimizing the impact of temperature on gas concentration acquisition;
4.Features valve action feedback information reception; valve drive function uses bus power, eliminating the need for a separate 24V power supply;
5.Includes automatic sensor fault detection, effectively preventing missed alarms;
6.Ultra-thin design with a simple and compact appearance.
