    What are the functions of the Newhb horizontal steel fire shutter door controller?

    1. Manual control function: in non-linkage state, the rolling curtain can be manually controlled to rise, fall and stop.

    2. Electronic lock function: controller matching electronic lock button box. When the electronic lock is opened to the green dot (clockwise rotation), manual control is effective; Manual control fails when the electronic lock reaches the red dot (reverse rotation).

    3. Phase sequence protection function: when the input line of the three-phase power supply is out of phase or out of phase, the phase sequence fault light on the main control board will turn on, and the motor will not be able to operate. After any two phase lines are switched or phase-missing faults are eliminated, the phase sequence fault light goes out and the motor works normally.

    4. Half-drop function: after receiving smoke signal or linkage half-drop signal, control the rolling curtain to drop from upper limit to middle limit, automatically stay "median residence time", then drop to lower limit.

    5. Full drop function: after receiving smoke signal or two east full drop signal, the control curtain will be reduced to the lower limit.

    6. Function of evacuation channel: when the dial 2 switch ON the right side of the main control panel is fully set to ON, after receiving smoke sensing signal or linkage half descending signal, the control curtain will drop to the middle limit. Only after receiving temperature sensing signal or linkage full descending signal, it will drop to the lower limit.

    7. Emergency stop function: when linkage, the electronic lock will be released automatically. Press any key and it will enter the emergency stop state.

    A. When the rolling curtain is above the middle limit: the rolling curtain stays in place "emergency stop time "(30 seconds), and then enters the normal linkage process.

    B. When the rolling curtain is below the middle limit: the rolling curtain rises back to the middle limit to stay "emergency stop time", and then enters the normal linkage process.

    What is the difference between dust explosion-proof motor and CT4 explosion-proof motor?

    Different IP levels: shell protection type "TD" classification is divided into two types: dustproof IP55, dust-tight IP65, CT4 explosion-proof motor IP54.

    Different temperature groups: the maximum surface temperature of CT4 equipment shall not exceed CT4, that is, 135°C, and the maximum surface temperature of dust explosion-proof shall not exceed 130°C.

    Electrical explosion-proof signs are different: gas explosion-proof motor is divided into BT4, CT4 explosion-proof grade, dust explosion-proof motor is selected, dust explosion-proof is higher than CT4 requirements.

    How long is the fire resistance limit of the Newhb horizontal steel fire shutter door?

    Newhb flat horizontal steel fire shutter door is based on BS EN 1634-1:2014 for non-heat insulation type horizontal sliding shutter door resistance test. After heating for 260 minutes, stop the test. During the test, the sample did not collapse, the unexposed surface did not continue to burn, no permeability loss, fire resistance integrity, fire resistance time can reach more than 4H, no heat insulation effect.

    What are the components of Newhb horizontal steel fire shutter door?

    Horizontal steel fireproof rolling shutter door is relatively rare in the domestic market, but its components are roughly similar. Its main components are: curtain, motor, box, control box, track, spindle, bracket plate, limiter, etc. And our common fire shutter door is the difference between the direction of its operation: horizontal steel fire shutter door is running horizontally.

    Newhb horizontal steel fire shutter door is generally used in what places?

    Flat horizontal steel fire shutter door is generally used in the fire partition of escalator, patio/shaft entrance, partition of escalator, openable compartmentation at void areas, travelators, truck dumping access, special purpose top or bottom void access or other horizontal entrance, which is a good supplement to the common vertical fire shutter door on the market.
