DescriptionThe HTRI-S intelligent interface module is designed to monitor a (NO) or (NC) dry contact. The interface module reports the status of the (NO) or (NC) contact to the control panel. The HTRI-series module is fully compatible, on the same Siemens-compatible panel circuits, with all other Siemens intelligent H-series detectors; Model HMS-series addressable manual stations, or any other addressable intelligent modules, such as Model HZM or Model HCP. All Model HTRI-series intelligent interface modules are UL listed. Environmental operating conditions for all Model HTRI-series modules are 32 degrees Fahrenheit (0 degrees Celsius) to 120 degrees Fahrenheit (49 degrees Celsius) with a relative humidity of no greater than 93%, non-condensing.
