Wireless Airbag WSD Series: Wireless Solutions for Safe and Anti-Pinch Industrial Doors

I. Product overview

In entrance and exit equipment such as industrial doors, fast doors, roller shutters, etc.Bottom safety anti-pinchIt is a key feature for the safety of people and cargo. Conventional wired airbags are connected by a helical wire, which existsWorn cables, tensile breaks, poor contactsand other safety hazards, and complicated installation and wiring.

Suzhou Jufu Intelligent Equipment Technology Co., Ltd.Self-developedWireless Airbag WSD SeriesIt adopts 433MHz wireless communication technology to send the command signal to the door control system wirelessly, which completely solves the safety hidden danger existing in the spiral line. The product hasFast response time, easy installation, strong anti-interference ability, high sensitivityand other features.

The WSD series is now availablewsd-001, wsd-002, wsd-003Three models to suit different door types and application scenarios.

Second, the principle of the product

The wireless airbag WSD system consists ofTransmitter, Receiver, Airbag Tube/Safety ContactsThree components:

• Airbag tube/safety edge: Installed at the bottom of the door body, deformation occurs in the event of obstruction, triggering the air pressure switch or squeeze signal
• transmitter side: Detects air pressure changes or safety edge signals and sends a stop signal wirelessly via 433MHz.
• receiving end: Installed on the control system side of the door, it stops or reverses the door movement immediately after receiving the signal.

When the airbag tube touches the shelter or the safety contact edge is squeezed, the transmitting end detects the signal change and immediately sends the command to the receiving end through wireless, and the receiving end controls the door body to stop or reverse through the relay output.

V. Core Functional Highlights

1. Wireless transmission, eliminating cable hazards

Using 433MHz wireless communication technology to send command signals to the control system, theCompletely solved the safety hazards that existed in the spiral line. No mechanically connected parts, fewer points of failure and longer service life.

2. Ready to use, easy to install

• Factory coded by default, ready to use out of the box.
• Transmitter power switch design (unplug the right side to open), no need for complex settings
• Receiver side code pairing key can be operated directly by pressing without opening the cover
• Suitable for old door renovation projects without destroying the original structure

3. Fast response and precise control

• WSD-002 response time <0.04 seconds, to meet the demand of high-frequency start and stop of the rapid door
• WSD-001/003 response time <0.1 sec, suitable for standard industrial scenarios
• Wireless transmission distance >30 metres, covering most industrial door installation scenarios

4. Multiple input methods for flexible adaptation

• Air Pressure Input: 2mbar air pressure switch to bottom airbag tube
• J2 terminal input(WSD-001): Support for safety touch edges, pass-through wicket switches, etc.
• Mode switching(WSD-001): S1 mode pulse output / S2 mode hold output

5. Low battery alert, easy maintenance

• Transmitter red indicator light is always on → power is low, need to replace the battery
• Blue indicator on the receiving end is flashing → low battery, replace the battery or stop flashing after re-power up
• WSD-002 supports low battery beep reminder (4 modes selectable: 5 sec/15 sec/60 sec/silent)

VI. Installation and use instructions

first use

Please make sure the power of the transmitter is turned on, if not, please remove the plug and toggle the switch to the right.

Code matching operation (if re-coding is required)

• WSD-001Press and hold the code key for 3 seconds at the receiving end (at the rubber plug) → blue light blinks → blow air to the air pressure switch at the transmitting end (or press the code key) → blue light turns on → blue light returns to normal at the receiving end, code pairing is successful
• WSD-002/003Press and hold the code pairing key for 3 seconds at the receiving end → red light flashes → blow/squeeze the safety contact at the transmitting end → red light turns on → red light returns to normal at the receiving end, code pairing is successful
