Gas-detection systems alerts personnel to dangers
Pfannenberg USA
The Patrol Series Flashing Sounders (photo) provide alarming related to fixed gas detection. These devices are designed to alert personnel of the need to evacuate when a hazardous gas (such as ammonia, carbon dioxide, Freon, methane, chlorine and others) is present. These gas-monitoring systems are designed for energy generation, wastewater treatment, landfill applications, food-and-beverage manufacturing, refrigeration, gas production, agricultural, chemical use and storage, and other industrial applications. The system offers 80 pre-programmed alarm tones with four stages for distinctive signaling of specific events. Such devices are well-suited for environments with high ambient noise levels or when the use of hearing protection may hamper a sounder’s effectiveness, or in bright environments where visual signals alone do not suffice. A single device in heavy-duty industry (>90 dB) can cover over 350,000 ft3 (visual) and 800,000 ft3 (audio) with an effective viewing distance of nearly a quarter of a mile, says the manufacturer. — Pfannenberg USA, Lancaster, N.Y.
