Tyco Extended Coverage Sprinklers are intended for the protection of areas larger than those specified in standard installation rules and for specific light, ordinary, or extra hazard occupancies. Extended coverage sprinklers are available in both standard response (EC) and quick response (QR-EC). They are available in upright, pendent, horizontal sidewall and recessed horizontal sidewall. These sprinklers are typically used in hotels, restaurants, office buildings, warehouses, and other areas where it is desirable to reduce the overall number of required sprinklers
