Check the listing for details. Kidde DAF Model 27121-0, Vertical Mount, Brass Hex Head, 190° F. Condition: New. Listed at 189.33 USD. The D-A-F is used for signaling overheat or fire conditions. D-A-F detectors are widely accepted, because they are designed with rate compensation. Rate-of-rise devices, on the other hand, are triggered by the rate of increase in ambient temperature and are subject to false alarms caused by harmless, transient thermal gradients such as the rush of warm air from process ovens.
