Introducing our NEW PI-10 Indicator Switch
Package for Curtain Type Fire Dampers
Pottorff is pleased to announce our PI-10 indicator switch package for our VFD curtain style blade fire dampers. The PI-10 features a single pole double throw micro switch and can be used to signal an alarm or fire control system to indicate blade closure on our dampers from a remote location.
The PI-10 can be used on both static and dynamic, 1-1/2 hour rated and 3 hour rated dampers. The PI-10 can be ordered factory mounted, or loose for field installation as an option on our VFD models. It can also be ordered as a stand alone model for retrofitting previously installed VFD dampers that need blade indication.
