SLA-01HY Wireless Remote-Controlled Audible-Visual Alarm Siren: A Reliable Solution for Industrial Safety and Emergency Management

In modern industrial environments, fast response and clear warning signals are critical to safety management. From construction sites and warehouses to tunnels, ports, and confined spaces, traditional wired alarm systems often struggle to meet the demands of large areas, harsh environments, and flexible deployment.

The SLA-01HY Wireless Remote-Controlled Audible-Visual Alarm Siren is designed to address these challenges, offering a practical, industrial-grade solution for overseas markets that require long-distance control, high visibility warnings, and reliable performance under extreme conditions.

Designed for Long-Distance Wireless Control

One of the key advantages of the SLA-01HY is its wireless remote control capability, available in 315MHz or 433MHz frequency options.

• The 315MHz version supports a control range of up to 500 meters, suitable for medium-sized facilities.

• The 433MHz version extends the control distance up to 2000 meters, making it ideal for large factories, warehouses, industrial parks, ports, and outdoor construction sites.

With a single button on the remote control, operators can activate or deactivate the alarm instantly, even from a long distance. The extendable antenna further enhances signal stability in complex industrial environments.

High-Visibility Audible and Visual Warning

The SLA-01HY combines audible and visual alerts to ensure warnings are noticed immediately, even in noisy or low-visibility conditions.

• 120dB adjustable alarm sound provides strong acoustic coverage while allowing users to reduce volume when noise regulations apply.

• High-brightness LED strobe light is available in red, yellow, blue, or green, enabling clear visual identification for different safety scenarios.

This combination makes the alarm highly effective for emergency alerts, evacuation warnings, restricted-area notifications, and equipment operation alerts.

Flexible Pairing for Scalable Alarm Systems

Unlike fixed one-to-one alarm systems, the SLA-01HY supports a learning code pairing function, enabling flexible system configuration:

• One remote control can manage multiple alarm sirens

• Multiple remotes can control a single alarm unit

This N+N pairing capability is especially valuable for overseas customers managing large-scale facilities or multi-zone operations, allowing centralized or segmented control without complex wiring or additional controllers.

Customizable Voice Messages for Global Applications

To meet the needs of international users, the SLA-01HY supports custom voice alarm messages. Alarm audio can be tailored for:

• Different industries (fire safety, security, construction, logistics)

• Multiple languages for multinational teams

• Specific warning instructions for emergency response

Voice files can be updated easily via USB flash drive (MP3 format, up to 4MB), without special tools or technical expertise. This feature significantly reduces maintenance time and allows quick adaptation to changing operational requirements.

Industrial-Grade Protection for Harsh Environments

The SLA-01HY is built with a spray-coated cold-rolled steel enclosure, offering excellent durability for outdoor and industrial use.

• IP65-rated dust and water resistance

• Operating temperature range: -40°C to +70°C

• Humidity tolerance up to 95%

These specifications ensure stable operation in extreme cold, high heat, heavy rain, dust, and coastal environments, making the alarm suitable for tunnels, mines, ports, shipyards, and outdoor construction projects without additional protective housing.

Wide Voltage Compatibility for Global Markets

To simplify installation and global deployment, the SLA-01HY supports multiple voltage options:

• DC12V / DC24V

• AC110V / AC220V / AC380V

This wide voltage compatibility allows the alarm to be used across North America, Europe, Asia, and industrial power systems without voltage converters. Wall-mounted installation and simple wiring further reduce installation cost and technical barriers for overseas customers.

Typical Application Scenarios

The SLA-01HY Wireless Remote-Controlled Audible-Visual Alarm Siren is widely used in:

• Construction sites and temporary work zones

• Warehouses and logistics centers

• Factories and industrial plants

• Tunnels and confined space evacuation systems

• Ports, shipyards, and offshore facilities

• Industrial parks and large outdoor areas

A Practical Choice for OEM and Industrial Buyers

With its long-distance wireless control, flexible pairing, customizable voice alerts, and industrial-grade durability, the SLA-01HY offers a balanced solution for businesses seeking reliable safety equipment without complex system integration.

For distributors, system integrators, and OEM customers, it provides a dependable foundation for industrial wireless alarm systems, emergency alert solutions, and remote-controlled safety infrastructure in global markets.
