Edwards EST SIGA-278 Pull Station

The SIGA-278 Double Action Fire Alarm Station is an addressable, normally-open, dry contact signal initiating device that requires two user actions to initiate an alarm. First, the upper door marked LIFT THEN PULL HANDLE must be raised to access the alarm handle. Second, the alarm handle must be pulled to initiate an alarm. The single input module mounted on the back of the unit supervises the station and sends an alarm signal to the Signature controller when the switch is closed (i.e., when the handle is pulled).
