The Series TY-FRL, 5.6 and 8.0 K-factor, extended-coverage horizontal sidewall sprinklers are solder-type spray sprinklers designed for use in commercial occupancies like churches, restaurant seating areas, hotels, educational facilities, offices, and more. With coverage up to 16 feet (4,9 m) wide by 24 feet (7,3 m) long, these sprinklers are designed for installation along a wall or the side of a beam and just beneath a smooth, flat, horizontal ceiling. Horizontal sidewall sprinklers are commonly used instead of pendent or upright sprinklers due to aesthetics or building construction considerations when piping across the ceiling is not desirable.
