A 1.5-hour UL-listed stainless steel fireproof door viewer is a specialized component designed to provide a clear, secure view through a fire-rated door while maintaining its fire resistance. Here’s a detailed description:
Product Overview
- Material: The door viewer is made from stainless steel, a durable and corrosion-resistant material. This construction ensures both strength and longevity, making it suitable for use in environments where both security and fire resistance are essential.
- UL Listing: The "UL-listed" mark indicates that the product has been tested and meets the rigorous standards set by Underwriters Laboratories (UL) for fire safety. In this case, the door viewer can withstand up to 1.5 hours of exposure to fire (known as a 1.5-hour fire rating). This means that the door viewer will continue to function properly and maintain its integrity for a specified period during a fire emergency.
- Fire Resistance: The primary feature of the viewer is its ability to withstand extreme temperatures without compromising its function. The viewer will not warp, degrade, or allow smoke and flames to pass through the door, maintaining the fire-rated door’s performance during a fire event.
- Design: Typically, the door viewer has a wide-angle lens that allows individuals to clearly view the area outside a fire-rated door, improving security and situational awareness. The lens is often made from high-temperature-resistant glass or optical-grade materials that can endure the heat from a fire without losing clarity.
- Installation: These viewers are designed to be easily installed into fire-rated doors, which are commonly found in commercial and industrial buildings, as well as in residential properties in areas with higher fire safety standards. Installation usually involves creating a hole in the door and securing the viewer with a mounting system that ensures it remains intact during a fire.
Applications
- Fire Doors: The product is specifically designed for use in fire-rated doors that are a part of fire-rated walls in commercial, industrial, and residential buildings. It allows individuals to safely view the hallway or exterior side of the door without opening it, which can be critical in maintaining fire safety protocols.
- Security and Safety: In case of a fire or emergency, the door viewer provides clear visibility to help assess the situation outside without compromising safety. It can be used in a variety of environments, including hospitals, schools, high-rise buildings, and factories.
