An overview: The fireproof rolling shutter controller produced by our company adopts single-chip microcontroller technology, combined with the complex factors of the fire scene, and is carefully designed and manufactured by selecting high-quality components. It is an ideal supporting product for fireproof roller shutter projects.
Two main technical parameters
Main power supply for working power
Backup power supply/
Allow external motor power<
Door feedback contact capacity/
Working environment temperature ℃℃
Relative humidity
Atmospheric pressure
Overall dimensions length, width and height
Three, main functions
Backup automatic switching function
Under normal circumstances, the controller is controlled by The main power supply works. When the main power is cut off, it automatically switches to the backup power supply. When the main power supply is restored, it automatically switches back to the main power supply and charges the backup power.
Release function
When there is a fault in the three-phase power and a fire alarm occurs on site, the controller automatically starts the quick release device, so that the roller shutter will stop when it drops to the neutral position by its own weight, and will delay the neutral delay time. Automatically descend to the bottom. If you press any key during the descent process, the roller shutter will stop immediately, delay the middle delay time, and then descend to the bottom.
There are two automatic control methods
① The two-step smoke temperature sensor is lowered to the position. After the smoke sensor is activated or the half-lowering signal is reached, the roller shutter is lowered to the mid-stop position. After the temperature sensor is activated or the full-lowering signal is lowered, the roller shutter is lowered again. to the lower limit position.
② The smoke sensor delay two-step lowering is in place. After the smoke sensor is activated or the half-lowering signal is reached, the roller shutter drops to the mid-stop position. After the delay, it drops to the lower limit position.
With fault detection function
①Three-phase power supply/main power failure
②Backup power supply disconnection or undervoltage
③Limiter failure and over-limit failure require motor cooperation
/>④The connection between the motor electromagnet and the controller is disconnected or short-circuited.
⑤The connection between the detector and the controller is disconnected
