Residual pressure monitoring system

The fire emergency evacuation residual pressure monitoring system collects residual pressure values between smoke proof stairs or front rooms and fire exits through residual pressure detectors, and uploads them to the residual pressure monitor through a non-polar two bus for data analysis and processing by the monitor. When the residual pressure exceeds the set range, the monitor emits an audible and visual alarm signal and displays and prints the alarm location. At the same time, the monitor uses an algorithm to control the residual pressure monitor to adjust the angle of the air valve actuator in real time, control the opening and closing of the bypass valve of the positive pressure air supply system, and ensure that the residual pressure value remains within a safe range.

JK-CO1001 Air Quality Monitor

When the car engine is running at full speed, due to insufficient combustion of gasoline, a large amount of exhaust gas containing C0 will be produced. Underground parking lots are enclosed environments with concentrated vehicles entering and exiting frequently, and the exhaust emissions are not easily discharged outdoors, which can easily accumulate a large amount of C0 gas and cause a pungent odor in the parking lot, damaging people's health.
The air quality monitoring system designed and developed by our company is suitable for monitoring air quality in underground parking lots. This system is an intelligent system that integrates industrial computer technology, communication, anti electromagnetic interference, digital sensing, and industrial two bus technology. It can perform 24-hour real-time automatic inspection of CO concentration or temperature and humidity in underground parking lots, give alarm prompts for CO concentration exceeding the standard or temperature and humidity values exceeding the standard, and link the mechanical exhaust system to ensure that the underground garage environment is within a safe range.

Number of monitoring circuits for different models：	One circuit can monitor 200 CO concentration controllers, and the CO concentration controller can monitor 64 CO concentration sensors.
Loop line system：	The monitor and controller, as well as the controller and CO concentration sensor, are connected via a non-polar signal two bus.
External dimensions：	469mm350mm110mm
main power supply：	AC220V (2 sealed lead-acid batteries, single battery DC12V/4.5AH)
