Pendent Fire Sprinkler Head, Quick Response, 1/2 in, 4.9 K, 175 deg F, White

Model F1RES LL pendent sprinklers are fast response sprinklers combining excellent durability, high sensitivity glass bulb and low profile decorative design. The F1RES LL horizontal sidewall sprinklers are equally attractive when above ceiling piping cannot be used. The 3 mm glass bulb pendent sprinklers permit the efficient use of residential water supplies for sprinkler coverage in residential fire protection design. The low flow F1RES LL sprinklers are specially engineered for fast thermal response to meet the sensitive fire protection application needs of the latest residential market standards (UL 1626 Standard). Upon fire conditions, rising heat causes a sprinklers heat sensitive glass bulb to shatter, releasing the waterway for water flow onto the deflector, evenly distributing the discharged water to control a fire.
