Fire alarm circuit board features

◆ The built-in eight-bit single-chip computer with A/D conversion has powerful analysis and judgment capabilities. Through the solidified operation program inside the detector, it can automatically complete the compensation for changes in external environmental parameters and the judgment of fire alarms and faults. The characteristic curve of the change of environmental parameters is stored, which greatly improves the real-time and accuracy of the whole system in detecting fire.

◆ Using electronic coding method, on-site coding is simple and convenient

◆ The indicator light flashes to prompt its normal working status, and its running status can be observed on site

◆ The bottom is sealed, which can effectively waterproof, dustproof, and prevent the damage to the detector caused by the harsh application environment.

The fire alarm circuit board also has functions such as electrical fire monitoring and alarm, linkage control, fault detection, shielding, and network communication.
