Siemens HTRI-D

The Siemens Fire Safety HTRI-series Intelligent interface modules are designed to provide the means of interfacing direct shorting devices to the fire-alarm control panel (FACP) loop circuit. The HTRI-series modules provide the most advanced method of address programming and supervision on the market combined with sophisticated control panel communication. Each HTRI-series interface module incorporates a microcomputer chip, and each interface module achieves the state of an ‘intelligent device’ through its microcomputer chip technology, combined with its sophisticated, bi-directional communication capabilities with the FACP.
