Siemens TRI-2D Dual Input Interface Module

The Siemens TRI-2D is a dual input addressable interface module designed for use with Siemens MXL fire alarm control panels. It provides two supervised input circuits, allowing for the monitoring of normally open (NO) or normally closed (NC) dry contacts from external devices such as conventional pull stations, waterflow switches, or other initiating devices. Each input is individually addressable, enabling precise identification and monitoring within the fire alarm system.

Key Features:

• Dual Supervised Inputs: Monitors two independent circuits, each capable of supervising NO or NC dry contacts, enhancing system flexibility.

• Individual Addressing: Each input can be assigned a unique address within the MXL system, allowing for precise identification and monitoring of connected devices.

• Multi-Color LED Indicator: Features a tri-color LED that provides visual status indications—green for normal operation, amber for trouble conditions, and red for active alarms.

• Compact Design: Mounts directly into a standard double-gang or 4-inch square electrical box, facilitating easy installation and integration into various environments.
