Alarm Lighting Fixed Amber/Green/Red LED PATLITE LR4-302LJBU-RYG

The PATLITE LR4-302LJBU-RYG is a fixed alarm lighting unit with integrated amber, green and red LEDs designed for visual signaling in industrial and commercial environments. The compact signal head has a 40 mm width and is intended for fixed mounting where a clear, multi-color indicator is required. The lamp runs on 24V DC and has a low maximum power consumption of 1.3 W, providing visible status indication while minimizing energy use. The unit complies with RoHS requirements for restricted substances.

Advantages

The fixed-design lamp delivers distinct color indication in a single compact housing, simplifying installation and wiring. Low power consumption reduces load on control systems and enables continuous operation without significant heat generation. The LED light source offers long operational life and consistent color output compared with conventional lamps. RoHS compliance supports installations where restricted-substance standards are required.

Suitable for

• Status indication on machinery and production lines
• Visual alarm or condition signaling in control cabinets and panels
• Workplace safety and zone identification in factories and warehouses
• Integration into automation systems for multi-state indication

Key specifications

• Colors: amber, green, red (three-position fixed)
• Supply voltage: 24 V DC
• Maximum power consumption: 1.3 W
• Body width: 40 mm
• Light source: LED
• Compliance: RoHS

How to use

Mount the unit in a visible location using appropriate fasteners for the mounting surface and connect to a 24V DC supply following local electrical codes. Ensure correct wiring for the three color outputs or the single combined input depending on your control wiring scheme. After powering, verify each color illuminates as expected by applying the corresponding control signal. Routine visual inspection ensures the lens remains clean and unobstructed to maintain visibility.

Usage recommendations

For reliable operation, install the lamp where ambient temperatures and environmental conditions match the product’s rated specifications; avoid direct exposure to high-pressure washdowns unless the product’s ingress protection and mounting method are specified for such conditions. Use proper wire sizing and protected connections when integrating with automation controllers to prevent voltage drop and ensure consistent illumination.
