Siemens ILED-XW Intelligent Remote Alarm Lamp P/N:S54370-B5-A1

The Siemens ILED-XW Intelligent Remote Alarm Lamp P/N: S54370-B5-A1 is an addressable remote status indicator designed for compatible Siemens fire alarm systems. It provides an additional tri-color LED indication for detectors and other devices installed on the same addressable device loop.

The ILED-XW features a rectangular wall-mount plate and incorporates dual built-in isolators. These isolators improve signaling-line circuit survivability and help the fire alarm control panel determine whether a short circuit is located before or after the remote lamp.

Product Functions

• Uses one unique device address
• Supports programmable system logic
• Designed for compatible Siemens fire alarm systems

Tri-Color LED Indication

The ILED-XW uses a programmable tri-color LED capable of displaying:

Green

Amber

Red

Typical operation is:

Green: Normal supervisory operation

Amber: Trouble condition

Red: Alarm condition

The actual LED operation is controlled by the programming and logic of the connected Siemens fire alarm system.

Intelligent Remote Indication

The ILED-XW provides remote visual indication for devices that may be concealed or difficult to observe directly.

Typical applications include devices installed:

• Above suspended ceilings
• Under raised floors
• Inside ventilation ducts
• Inside normally locked rooms
• In vaults
• In concealed equipment spaces
• In other difficult-to-view locations

Because the ILED-XW is independently addressable, its operation can be controlled through compatible fire alarm system programming.

Addressable Operation

The ILED-XW operates directly on the compatible Siemens addressable device loop.

It requires:

One unique device address

The device can be programmed electronically using the Siemens:

DPU — Device Programmer / Test Unit

This allows the remote lamp to be individually identified and supervised by the fire alarm control panel.

Dual Built-In Isolators

The ILED-XW incorporates dual line isolators.

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

This improves circuit survivability while helping the control panel determine whether the short is located:

Before the device

or

After the device

The isolators also improve troubleshooting by helping identify incorrectly configured Class X devices.

Class X Capability

The ILED-XW can support Class X circuit configurations when used with compatible Siemens control equipment.

The built-in isolation functionality helps unaffected portions of the signaling line remain operational during certain short-circuit conditions.

Compatible devices can also be installed between isolators according to the circuit limitations specified by Siemens.

Polarity-Insensitive Mode

The ILED-XW can alternatively operate in:

Polarity-Insensitive Mode

When configured this way, reversing Line 1 and Line 2 does not affect device performance.

The operating mode is selected according to the signaling-line circuit design and required isolation functionality.

Wall-Mount Configuration

The specific ILED-XW configuration provides:

Model: ILED-XW

Part Number: S54370-B5-A1

Mounting: Wall

Plate: Rectangular

Electrical Box: Single-gang

Indicator: Tri-color LED

The related:

ILED-XC — P/N S54370-B6-A1

is the round ceiling-mount version designed for a 4-inch octagonal electrical box.

System Compatibility

The ILED-XW is designed for compatible Siemens systems including:

Desigo Fire Safety

Cerberus PRO

FireFinder XLS

Compatible panel families include applicable FC, FV, and modular Siemens fire alarm platforms.

Exact compatibility should be verified against the specific control panel and system software.
