LED Scanner Flasher Indicator Board – Knight Rider Scan, Trigger Alarm Input & 12VDC

The LED Scanner is a compact LED flasher module designed to simulate a security scanner effect — the same sweeping LED animation associated with vehicle alarm systems. It outputs a continuous scanning pattern across its power LEDs under normal operation, and switches to a distinct alarm-state pattern on the middle LEDs when its Trigger+ input is activated.

Blinking speed is adjustable via an onboard potentiometer. The board connects via an elevator-type terminal block and includes reverse-polarity protection to prevent damage from incorrect wiring.

Key Features

• Knight Rider-style LED scanning simulation pattern
• Trigger+ input for alarm-state activation — flashes middle LEDs when triggered
• Blinking speed adjustable via onboard potentiometer
• Elevator-type screw terminal for wiring connections
• Reverse polarity protection
• 12 VDC power supply

Product Benefits

• The scanning animation provides a visible deterrent effect for vehicle or property security applications without requiring a full alarm system
• The Trigger+ input allows the unit to respond to an external alarm signal, changing the LED pattern to indicate an active alarm state
• Potentiometer-based speed adjustment lets the installer tune the scanning rate to the desired visual effect without additional components
• Elevator terminal connections simplify wiring in automotive and panel installations
• Reverse polarity protection prevents board damage if power leads are connected incorrectly
