1⁄2" Orifice Horizontal Sidewall Automatic Sprinkler Omega HEC-12EC PRO ProhibitorTM Product Description occupancies in accordance with current NFPA 13 Standards (for up to 16' x 20' coverages). For all models of ProhibitorTM Sprinklers, an optional 35⁄8" diameter light gauge escutcheon closure plate is available, for use where the wall penetration is greater than the recommended 21⁄4" diameter. The escutcheon closure plate fits between the base of the escutcheon and the mounting surface. For all models of ProhibitorTM Sprinklers, an optional 41⁄2" diameter x 1⁄8" thick security closure plate is available for use where additional security is a consideration. The security closure greatly reduces the possibility of inserting a tool, prybar or other device behind the sprinkler. The security closure plate fits between the base of the escutcheon and the mounting surface. For all models of ProhibitorTM Sprinklers, the optional Ident-A-FireTM feature is available to provide an alarm signal upon activation of the sprinkler. ProhibitorTM Sprinklers are available in two standard finishes, brass and chrome plated. Their mating escutcheon is available in three standard finishes, brass, chrome plated and white painted, with additional special finishes available. Operation: A fusible alloy pellet is compressed with a bearing disc into a copper housing by a ball plunger. Heat is absorbed by the heat collecting fins and conducted to the alloy pellet. At the rated temperature the alloy melts, causing the ball plunger to drop, freeing balls from the retaining groove. This movement allows system water pressure to force the orifice sealing mechanism and deflector assembly open. Water is then discharged in a designed flow pattern. The Omega ProhibitorTM Model HEC- 12EC PRO Automatic Sprinklers have been specifically designed for use in institutional occupancies, such as correctional facilities and mental health facilities, where the occupants may attempt to tamper with or otherwise employ the sprinkler to injure themselves or others. The horizontal sidewall style ProhibitorTM HEC-12EC PRO sprinklers are recessed into the mounting surface with only a portion of the heat collecting fin assembly projecting into the protected space. The heat collecting assembly has an average breakaway load of 68 lbs., and a maximum breakaway load of 85 lbs. Unlike other institutional sprinklers, the escutcheon plate and optional closure plates are firmly attached to the recessed sprinkler body with tamper resistant retaining screws. The Omega ProhibitorTM sprinklers are designed with an aesthetically pleasing, low profile silhouette. They feature a spray pattern that has been shown to be effective in the control or extinguishment of fire.
