The Kidde® Model 878752 Abort Station features a large, easy-to-operate abort push button. The momentary type switch is very easy to see due to its highly visible yellow color. The abort station stainless steel faceplate is clearly labeled with operation procedures—eliminating indecision and hesitation. The Backbox is painted with red enamel and is provided with four 1/2-inch knockouts. The pre-drilled and tapped mounting tabs allow for easy attachment of the abort station. To make the Abort Station an addressable SLC device for use with Kidde Intelligent control units, one SmartOne® Model AI monitor module (purchased separately) must be installed into the backbox. The Model AI monitor module is seated inside a bracket (included) and easily installs with two mounting screws.
