Siemens (Pyro) | HTRI-S-RC

The Siemens HTRI-S is an intelligent, addressable interface module designed to integrate dry-contact devices into Siemens fire alarm control panels, such as the FireFinder XLS and FS-250 systems. This module enables the monitoring of devices like conventional heat detectors, manual pull stations, or other normally open contact devices within an addressable fire alarm system. 

Key Features:

• Single Input Monitoring: The HTRI-S module supervises a single input circuit, allowing for the connection of a normally open or normally closed dry-contact device. 

• Compact Design: Its compact size facilitates easy installation in standard electrical boxes, making it suitable for various applications. 

• LED Indicator: Equipped with a red LED that provides visual indication of the module’s status, flashing during normal operation and steady on when the input device is activated. 

• Addressable Communication: Communicates directly with compatible Siemens fire alarm control panels, ensuring precise identification and monitoring within the system.
