The history of the development of the Fire Horn/Siren began in the middle 1800s when it was developed as a double billowed pumb to furnish air to a firemen’s smoke mask. The foot pedal was depressed by an operator to pump air into a second spring tensioned bellows to keep a constant flow of air to the helmet. When a Firefighter went into a confined area he was attached to a lifeline and used a code system based on pulls of the lifeline to communicate with the pump operator. These commands are indicated on the large brass plate attached to the top of the pump.

In the early 1900s, more efficient air pumps were developed, so the company adapted a large brass horn to the unit and marketed the pump as a Fire Siren
