Siemens HTRI-S Intelligent Interface Module
The Siemens HTRI-S is an intelligent interface module designed to monitor and report the status of normally open (N.O.) or normally closed (N.C.) dry contact devices within Siemens fire alarm systems. It facilitates the integration of various devices, such as conventional pull stations or supervisory switches, into addressable systems, ensuring precise monitoring and communication with the fire alarm control panel (FACP).
Key Features:
• Contact Monitoring: Capable of supervising N.O. or N.C. dry contacts, allowing for versatile integration of different devices.
• Intelligent Addressing: Utilizes microcomputer technology for reliable communication with the FACP, ensuring accurate status reporting.
• Polarity-Insensitive Wiring: Simplifies installation by eliminating concerns about wiring polarity.
• Multi-Color LED Indicator: Provides visual status updates with green for normal operation, amber for trouble conditions, and red for active states.
