Warning sign TP-4/H7

Warning Sign – Effective Protection and Information

The TP-4/H7 warning sign is a reliable device for detecting hydrogen leaks, designed for indoor installation. Its purpose is to provide immediate alerting of potential hazards, enabling rapid response and minimizing risk. Thanks to its clear, pulsating red LED illumination and optional audible siren, the sign effectively draws attention during emergency situations.

Construction and Application

The TP-4/H7 sign is part of gas detection systems and works in conjunction with WG, WG.EG, WG.EG.x, or WG.NG detectors and GAZEX control modules. Its construction is based on LED technology, ensuring long service life and low power consumption. The warning message “HYDROGEN LEAK – CAUTION” remains invisible until a hazard is detected—then it illuminates with intense red light, signaling the need to exercise caution. The option to connect an acoustic alarm further enhances alert effectiveness.

Signs from the TP-4 series are not intended for use in hazardous zones classified for explosive gases, vapors, or dusts—this is a critical limitation due to their design. They are ideal for indoor applications in industrial, commercial, and public utility facilities where hydrogen leak risks exist.

Key Features and Benefits

• Clear Visual Signaling: Pulsating red LED illumination ensures excellent visibility even under poor lighting conditions.
• Audible Signaling: Optional acoustic siren (65 dB/1m) provides additional alerting, especially critical in noisy environments.
• Low Power Consumption: LED technology ensures very low energy usage.
• Durable Construction: High-quality materials guarantee long-term reliability and durability.
• Easy Installation: Designed for simple wall-mounted or suspended installation.
• Legible Text: Standard letter height of 35 mm ensures good readability from a distance.
• Hidden Text in Standby Mode: The warning message appears only upon hazard detection, preventing habituation to constant visual cues.
• 230 V Power Supply: Enables straightforward connection to standard electrical networks.
