Pedestrian and Driver Warning for Automated Gates and Barriers
The DSG21 provides a clear spoken warning and visible LED indication while automated gates or barriers are operating. Unlike a conventional alarm tone, the voice message explains that movement is taking place and instructs pedestrians and drivers in or approaching the operating area to keep clear, helping to reduce the risk of personal injury or vehicle damage.
🔊 Voice warning: “Warning. Automatic barrier operating. Please keep clear.”
Amber LED indication while the barrier is operating
Preloaded and ready for first use
The DSG21 is supplied with 10 commonly used gate and barrier warning messages already installed, ready for the preferred message to be selected without first programming the audio.
The message, volume, LED colour and flash pattern can be selected using the included wireless configuration controller.
Operation
When activated, the DSG21 provides the selected voice message and LED warning. The message repeats continuously for as long as power remains applied.
10 preloaded warning messages
- Warning. Automatic gate operating. Please stand clear. (male voice)
- Warning. Automatic gate operating. Please stand clear. (female voice)
- Caution. Moving gate. Keep clear of the operating area.
- Warning. Automatic barrier operating. Please keep clear. (male voice)
- Warning. Automatic barrier operating. Please keep clear. (female voice)
- Caution. Automatic access equipment operating. Please keep clear.
- Please wait until the gate has stopped before proceeding.
- Please wait until the barrier has stopped before proceeding.
- Caution. Vehicle access point. Please proceed with care.
- Pedestrians, please keep clear of the vehicle access route.
Included wireless configuration controller
Convenient control of messages, volume and LED settings
The wireless configuration controller is included with the DSG21 and provides convenient control of:
- Select a preloaded message
- Adjust the voice volume
- Choose the LED colour
- Select the flash pattern
- Test, play, pause or stop the message
As the fitted lens affects the final sound level, the controller allows the installer to adjust and assess the volume from a practical listening position with the lens in place. This gives a more representative indication of the finished sound level and avoids repeatedly removing and refitting the lens.
If the controller is unavailable, the main operating settings can also be adjusted using the onboard buttons beneath the lens.
One unit, five visual indications
The DSG21 uses a single opaque white lens, with the displayed LED colour selected electronically to suit its intended use. The colour can also be changed later if requirements change.
The same DSG21 can therefore support automated gate and barrier warnings as well as related security, access-control and status applications, without changing the lens or stocking separate coloured versions.
RED - higher-priority warning
AMBER - movement or caution
GREEN - status or permission
BLUE - security or access control
WHITE - general indication
Selectable LED operating modes
✹ FAST FLASH - rapid flashing warning
✦ SLOW FLASH - slower flashing warning
● CONSTANT - continuous illumination
↻ ROTATING EFFECT - simulated rotating-light pattern
⊘ LED OFF - voice warning without LED illumination
The LED colour and operating mode can be selected using the wireless configuration controller or onboard buttons.
Simple two-wire power connection
The factory-fitted two-conductor cable can be connected to a suitable switched 12-36V DC output from the existing gate or barrier controller, allowing the voice message and LED warning to operate while the gate or barrier is moving.
