½” NPT frangible bulb type automatic sprinklers.

Hazard Involved

There is no evidence these products have ever been tested to the requirements of any testing and certification organization, including FM Approvals. As such, these automatic sprinklers cannot be relied upon to react to or control a fire. Failure by any of the following mechanisms is possible: failure of the thermal element, orifice leakage, premature or delayed operation, bulb strutting (incomplete fracture), ejection of the deflector, inadequate or excessive discharge rate, corrosive attack, failure to operate, failure to produce an adequate discharge pattern, etc. Of further note is the suspected use of an o-ring type orifice seal, a design which has historically been proven to be unreliable and possibly dangerous. Some o-ring type sprinklers have been subject to mandatory recall per the United States Consumer Product Safety Commission.
