Edwards Fire Safety mechanical heat detectors have been recalled because they might not work. The detectors act as sensors that trigger fire alarms or security panels when elevated heat is detected. The recalled detectors can fail to activate in reaction to rising temperatures.
The faulty detectors were sold across models, between January 1979 through May 2018, from Edwards, Interlogix, Grainger P/N, Honeywell Security, and Mirtone. The can be wall- or ceiling-mounted, and are labeled with “135F” and “NOT A LIFE SAFETY DEVICE.” For a full list of model numbers, see the U.S. Consumer Product Safety Commission recall notice. About 85,000 units are included in the recall, but no incidents or injuries have been reported at the time of the recall.
In facilities where the mechanical heat detectors are used in life-safety applications (for example, in elevator shafts, or in lieu of smoke detectors, manual pull stations, or sprinklers in particular settings), facility managers should immediately contact the fire alarm company who installed the system or that currently services the property for free replacement and installation of the heat detector, according to the recall notice. The service provider will receive a refund from Edwards once they provide evidence the original detector was destroyed. The refund applies only to units manufactured after January 1, 2004.
More information on the recall can be found on the Edwards website.
