The Siemens HTRI-MZ Intelligent Interface Module is designed to provide the means of interfacing direct shorting devices to the Device Program / Test Unit (Model DPU) for various Siemens ─ Fire Safety fire-alarm control panels (FACPs); which include the 50-point, 252-point as well as 504-point addressable fire systems.
In general, the Siemens HTRI-MZ provides the most advanced method of address programming and supervision ─ including sophisticated FACP-communication ─ in the fire and life safety market. Also, each Model HTRI-M | -MZ interface module uses microcomputer-chip technology; and advanced bi-directional communication capabilities with the respective Siemens – Fire Safety FACP.
Each Model HTRI-M | -MZ interface module is programm using Model DPU, which is a compact, portable and menu-driven accessory that makes programming and testing a given interface more accurately and efficiently than ever before. Model DPU eliminates the need for mechanical addressing mechanisms ─ such as program jumpers, DIP switches, or rotary dials ─ since Model DPU sets the interface address of Model HTRI-M | -MZ into its microcomputer-chip, nonvolatile memory electronically.
