This manual provides installation, setting, testing, and troubleshooting instructions for the FJKJZ04 electronic fireproof lock box controller used for fire…
The FJKJZ04 electronic fireproof lock box controller is an intelligent control device designed for public fire safety, specifically for controlling fire shutters. It features a microcomputer control chip capable of processing various signals to manage the shutter's rise, stop, and fall actions. The device includes manual buttons on the controller and two remote manual button boxes for operation. It can link with the fire control center to receive control signals and automatically respond to fire detector signals (smoke and temperature) within one second to control the shutter's descent mode. The controller also features a speed release mechanism that allows the shutter to descend by its own weight in case of power failure, along with a configurable mid-position wait function. It includes multiple feedback signals for faults, fire alarms, and shutter positions, and can automatically detect faults such as battery issues, phase loss, and motor coil failures. The device is equipped with a battery and automatic switching circuit to ensure operation during power outages, with a charging function that prevents overcharging and over-discharging. It also features a key lock to prevent unauthorized operation and automatic unlocking during fire alarms. The product is designed and manufactured in strict accordance with the 'GA 386-2002' public security industry standard of the People's Republic of China. This manual is written in Chinese.
