Uata ►rieet 2108 Engineered Systems IPF Series TM Discovery Thermal Detector j DIC.T • description The AsBuilt intelligent analog addressable thermal detector (DISC -T) y w operates seamlessly with the AsBuilt IP Fire Series TMA network fire control. The DISC -T communicates to and is managed and controlled by the IPF Series TM analog loop module (ALM).
