The Edwards EST SIGA-278 is a Signature Series intelligent addressable manual pull station featuring double-action, single-stage operation. To initiate an alarm, the user must lift the upper door marked “LIFT THEN PULL HANDLE” and then pull the alarm handle.

The device incorporates an integral microprocessor, allowing alarm decisions to be made at the station level, improving system response time and reducing sensitivity to line noise. Electronic addressing is handled by the Signature Loop Controller, eliminating manual switch or dial configuration.

The SIGA-278 is constructed of durable red Lexan and includes a keyed reset mechanism. It is designed for installation in commercial fire alarm systems utilizing Edwards Signature Loop Controllers.
