Description
The supervisory pressure switch detects a fall in pressure within a Kidde Fire Systems nitrogen pilot cylinder, when provided as a component within a Kidde Fire Systems High Pressure or Low Pressure Carbon Dioxide Suppression System. The cylinder supervisory pressure switch can be wired for either normally open or normally closed operation, depending on installation requirements. Installers field fit the switch onto the compatible nitrogen pilot cylinder. This switch also provides supervision performance backwards compatibility when replacing a legacy nitrogen pilot cylinder that had been factory fitted with the legacy supervisory switch.
