Siemens XTRI-R Single Intel Interface Module P/N:S54370-B1-A1

The Siemens XTRI-R Single Intel Interface Module P/N: S54370-B1-A1 is an intelligent addressable interface device designed for compatible Siemens fire alarm systems. It combines one supervised dry-contact input with one addressable Form C relay output, providing both monitoring and control capabilities from a single module.

The XTRI-R incorporates Siemens ISOtechnology with dual built-in isolators, providing enhanced signaling-line circuit survivability and short-circuit isolation. It can also operate in polarity-insensitive mode when isolation functionality is not required.

Single Input Monitoring

The XTRI-R provides:

One supervised dry-contact input

The input can monitor:

Normally Open (N.O.)

or

Normally Closed (N.C.)

contacts.

Typical monitored devices can include waterflow switches, valve supervisory switches, pressure switches, equipment status contacts, conventional initiating devices, and other compatible dry-contact equipment.

Form C Relay Output

The XTRI-R incorporates:

One Form C relay output

The relay provides:

Normally Open (N.O.)

Normally Closed (N.C.)

Common (C)

connections.

This allows the compatible Siemens fire alarm system to control external equipment according to programmed system logic.

Monitor & Control Operation

The XTRI-R combines monitoring and control functions within one intelligent addressable module.

Its supervised input can monitor the status of an external device while its Form C relay can control another compatible circuit or piece of equipment.

This can reduce the need for separate monitor and relay modules in applications requiring both functions at the same location.

Built-In Dual Isolators

The XTRI-R incorporates:

Two built-in line isolators

When configured in isolator mode, the module can isolate a signaling-line short occurring on either side of the device.

This helps unaffected sections of the addressable circuit remain operational during certain short-circuit conditions.

Class X Capability

The XTRI-R supports enhanced Class X signaling-line circuit configurations when used with compatible Siemens equipment.

Its integrated isolation architecture improves circuit survivability and can reduce the need for separate external isolator modules.

Short-Circuit Diagnostics

The dual-isolator architecture helps compatible Siemens systems determine whether a signaling-line short is located:

Before the XTRI-R

or

After the XTRI-R

This provides additional diagnostic information when troubleshooting addressable circuit faults.

Polarity-Insensitive Operation

The XTRI-R can alternatively operate in:

Polarity-Insensitive Mode

This configuration can be used when the integrated isolation functionality is not required.

The operating mode is determined by the signaling-line circuit design and compatible Siemens system configuration.

Multi-Color LED

The XTRI-R incorporates a multi-color status LED.

Typical indications include:

Green: Normal supervisory operation

Yellow: Trouble condition

Red: Locate or active condition

The LED provides local visual indication of module and circuit status.

Electronic Address Programming

The XTRI-R uses electronic addressing rather than mechanical DIP or rotary switches.

Compatible programming equipment includes:

DPU — Device Programmer / Test Unit

The device address can be programmed and verified electronically before the module is placed into service.

XTRI Series Comparison

The Siemens XTRI family includes:

XTRI-S — Single supervised input

XTRI-D — Dual supervised inputs

XTRI-R — Single supervised input with Form C relay output

All three models incorporate dual built-in isolators and support compatible Siemens intelligent fire alarm systems.
