Description
The Siemens HTRI-D is a dual-input module that interfaces and supervises field contacts in addressable fire alarm systems. It connects to normally open or normally closed devices and reports their state to the panel. Dynamic supervision continuously checks circuit integrity, while a single address covers both inputs.
It operates over a two-wire circuit, and SureWire technology keeps the connection polarity insensitive to simplify wiring. A multi-color LED shows green, amber, or red to indicate system status. The module mounts in a 4-inch square back box and carries UL, ULC, FM, CSFM, and NYCFD approvals.
Frequently Asked Questions
What is the Siemens HTRI-D used for?
It supervises and monitors two sets of dry contacts on a single address, commonly a waterflow switch and its valve tamper switch, reporting status to the FACP.
What is the HTRI-D compatible with?
It works on Siemens addressable FACP loops alongside H-series detectors, HMS-series manual stations, and other addressable intelligent modules such as HZM and HCP.
How is the HTRI-D's address set?
The address is set electronically with the Model DPU programmer/tester, which writes it to non-volatile memory and eliminates DIP switches, jumpers, and rotary dials.
