Optical-acoustic signaler Gazex SL-32 12V DC pulsating red LED 105/70 dB IP54

Gazex SL-32 is an optical-acoustic signaler designed for 12V DC systems, combining a pulsating red LED lamp with a dual-level sound output of 105/70 dB. The unit is intended for alarm, warning and signaling applications in industrial, commercial and vehicle installations where clear visual and audible alerts are required. Its IP54-rated enclosure provides protection against limited dust ingress and splashing water, making it suitable for indoor locations and protected outdoor mounting.

Advantages

The device integrates a high-visibility pulsating red LED with a two-level acoustic output to deliver synchronized visual and audible alerts. Low-voltage 12V DC operation allows compatibility with common vehicle and battery-backed alarm systems. The compact design and IP54 protection enable installation in areas exposed to dust and occasional moisture while maintaining reliable performance. The straightforward electrical characteristics simplify system integration and reduce the need for additional power conversion.

Suitable for

• Alarm and warning systems in industrial facilities
• Commercial premises such as shops, warehouses, and service centers
• Vehicle-based alarm and signaling installations (12V systems)
• Entryways, control rooms and equipment cabinets requiring combined visual and audible alerts

Key specifications

• Power supply voltage: 12 V DC
• Optical indicator: pulsating red LED
• Acoustic output levels: 105 dB and 70 dB
• Ingress protection: IP54 (protection against dust and splashing water)
• Combined optical and acoustic signaling in one enclosure

How to use

Install the signaler on a stable surface using appropriate fasteners and ensure the mounting location provides clear visibility of the red LED. Connect the device to a 12V DC supply following the system wiring diagram and observe correct polarity. Configure the controlling alarm or signaling panel to trigger the optical and acoustic outputs according to the required alert logic. Verify operation by activating the system and confirming both pulsating light and sound levels are functioning as expected.

Usage recommendations

Position the unit at a height and angle that maximizes visibility for personnel and minimize obstructions that could block the LED. For outdoor or harsh environments, install the device under a protective cover or within an enclosure that preserves IP54 conditions. Regularly inspect mounting, wiring connections and the enclosure for dirt accumulation or moisture; clean with a dry or slightly damp cloth and disconnect power before maintenance.
