Installation of XLMS1-RC Residual Pressure Controller Inside the Positive Pressure Fan

XLMS1-RC Residual Pressure Controller

●XLMS1-RC Residual Pressure Controller Functions:

Monitors the pressure working status and fault alarm information of all monitored areas in real time, and uploads the working status and alarm information to the control room XLMS1-H200 residual pressure monitoring host;

●Residual Pressure Monitoring System Product Composition:

XLMS1-RC Residual Pressure Controller

XLMS1-RS Residual Pressure Sensor

XLMS1-24V-NM Electric Bypass Valve Pressure Relief Valve

XLMS1-H200 Residual Pressure Monitoring Host

The residual pressure monitoring system mainly consists of: residual pressure monitor, residual pressure detector, residual pressure controller, electric actuator, air tube, and air tube end panel.

Residual pressure value in smoke-proof stairwells: 40–50Pa

Residual pressure value in anterooms and combined anterooms: 25–30Pa.

★ When the pressure difference exceeds the set value (50Pa for stairwells, 30Pa for anterooms), the residual pressure detector sends an alarm signal to the residual pressure controller, which then controls the electric actuator to open the bypass valve and begin pressure relief.

★ When the pressure difference reaches the set value range (40Pa for stairwells, 25Pa for anterooms), the residual pressure controller controls the electric actuator to close the bypass valve, completing the pressure relief.

Residual pressure controller aliases: Also known as residual pressure controller, pressure relief controller, residual pressure zone controller, air damper controller, bypass valve controller, positive pressure air damper controller, residual pressure control unit, etc.
