The HTRI-M monitors a normally open or closed dry contact and reports the contacts status to the control panel. Fully compatible on the same FireFinder XLS and FS-250 circuits with all intelligent H-Series detectors, HMS Series addressable manual stations, or any other addressable intelligent modules, such as Model HZM or Model HCP.
