Siemens HTRI-R Addressable Switch Interface Module

The Siemens HTRI-R is an addressable switch interface module designed to monitor and report the status of normally open (NO) or normally closed (NC) dry contacts within a fire alarm system. It features an integrated Form C relay, allowing it to control external devices as needed. This module is compatible with Siemens FireFinder-XLS and FS-250 systems. 

Key Features:

• Integrated Relay: Incorporates an addressable Form C relay for controlling external equipment.

• Dynamic Supervision: Provides continuous monitoring of connected devices to ensure system integrity.

• Polarity Insensitive Wiring: Simplifies installation by allowing connections without concern for polarity.

• Multi-Color LED Indicator: Utilizes a tri-color LED to display system status—green for normal operation, amber for trouble conditions, and red for active states.

Specifications:

• Operating Voltage: 30 VDC maximum.

• Current Consumption: 1.3 mA during polling.

• Relay Contact Ratings:

• Resistive Load: 4A at 125 VAC or 30 VDC.

• Inductive Load: 3.5A at 120 VAC (0.6 power factor); 3.0A at 30 VDC (0.6 power factor).

• Operating Temperature Range: 32°F to 120°F (0°C to 49°C).

• Humidity Range: Up to 93% relative humidity, non-condensing.

The HTRI-R module mounts directly into a standard 4-inch square or double-gang electrical box and includes a 5-inch square faceplate for a clean installation. Its design ensures reliable performance in monitoring and controlling auxiliary devices within a fire alarm system.
