Alert Summary

FM Approvals has been made aware of automatic fire sprinklers found in Vietnam bearing a counterfeit FM Approvals mark. FM Approvals has neither tested nor certified this product.

Product Identity

The sprinklers bear the marking “TYCO” on the wrench boss and Tyco SINs on the deflector but the identity of the manufacturer is unknown. The products are similar in appearance to the Tyco Fire Products TY3151, TY3251, and TY3351 sprinklers.

Description

½” NPT frangible bulb type automatic sprinkler.

Hazard Involved

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. Some o-ring type sprinklers have been subject to mandatory recall per the U.S. Consumer Product Safety Commission.

The sprinklers were not produced by Tyco Fire Products.
