Information About 500-896224
The 500-896224 is part of Siemens’ TRI-R interface module series, built for integration into MXL family fire alarm systems. This unit monitors a normally open dry contact and reports its condition directly to the FACP. It also provides a Form-C relay that can be programmed for shunting or controlling auxiliary devices. Both the relay and the input share the same address but are managed as separate functions, offering flexible configuration options. The compact design and addressability of the TRI-R make it well-suited for custom fire system applications requiring intelligent control and supervision.
Key Features:
- Dual Functionality: Monitors a normally open dry contact and provides a Form-C relay.
- Addressable Design: Input and relay share the same address but can be controlled independently.
- Flexible Applications: Ideal for shunting or controlling external equipment from fire panels.
- System Compatibility: Designed for MXL, MXLV, and MXL-IQ Siemens fire alarm systems.
- Compact Installation: Lightweight, small form factor for easy mounting.
- Reliable Monitoring: Reports real-time contact status to the fire alarm control panel.
- Discontinued Unit: Still available as surplus replacement for legacy systems.
The 500-896224 delivers the versatility and intelligence required for relay control and monitoring in MXL fire system installations.
