Description
The Kidde Fire Systems Nitrogen Pressure Operated Siren is designed for use with the 108 cu. in. pilot cylinder, the 1040 cu. in. pilot cylinder and the 2300 cu. in. Siren Driver Cylinder. Pressure Operated Sirens are used where mechanical-pneumatic predischarge or discharge alarms are required (typically where electrical sirens are not permitted).
The siren consists of a cast bronze body and a brass rotor mounted on a stainless steel shaft and sealed ball race. A red painted steel hood protects the unit. A filter is positioned in the inlet stub on the body immediately before the flow-controlling nozzle.
