The AS-1 Abort Station is made to delay the discharge of gaseous fire suppression systems when the momentary Mushroom button is pressed.
The AS-1 consists of a red mushroom button on a metal single gang switch plate. The wording “SYSTEM ABORT” is silk-screened in red enamel ink. The standard button includes a SPST N.O contact. Additional contact blocks can be added. Added contacts may be N.O. or N.C.
