The Siemens SLHSWR-F Red Wall Horn Strobe P/N S54329-F22-A1 is an indoor wall-mounted fire alarm notification appliance designed to provide both audible and visual emergency signaling. It combines an electronic horn with a clear LED strobe in a red housing marked FIRE, making it suitable for commercial and institutional fire alarm applications. Siemens identifies model SLHSWR-F with part number S54329-F22-A1 in its official ordering information.
Part of the Siemens SL Series, the SLHSWR-F uses energy-efficient LED strobe technology and selectable horn settings to provide flexible notification performance. Its compact wall-mount design helps create a clean finished appearance while supporting professional fire alarm system installations.
Audible and Visual Fire Alarm Notification
The Siemens SLHSWR-F combines an audible horn and visual strobe in one notification appliance. The horn provides a clear emergency signal, while the integrated LED strobe delivers visible notification during an alarm condition.
This combined design can reduce the number of separate notification devices required in areas that need both audible and visual signaling.
Four Selectable Candela Settings
The SLHSWR-F provides multiple field-selectable strobe output settings, allowing technicians to adjust the visual intensity according to the approved fire alarm system design.
Available candela settings include:
- 15 candela
- 30 candela
- 75 candela
- 110 candela
The selectable design gives installers greater flexibility when using the same appliance in different areas of a building.
Selectable Horn Operation
The Siemens SLHSWR-F also provides configurable audible output. Installers can select between temporal and steady horn patterns as well as high and low sound output settings.
This flexibility allows the appliance to be configured according to system requirements while maintaining a consistent product platform across multiple locations.
Key Features
- Red wall-mounted horn strobe with FIRE lettering
- Siemens part number S54329-F22-A1
- 15, 30, 75, and 110 cd selectable strobe settings
- Temporal or steady horn operation
- High or low audible output
- Energy-efficient LED visual notification
Energy-Efficient LED Strobe Technology
The SL Series uses LED technology to provide efficient visual alarm notification. Compared with traditional xenon-based strobe designs, LED notification appliances can help reduce current demand on compatible notification appliance circuits.
Lower current requirements may provide greater flexibility when designing NAC power capacity and appliance layouts, depending on the complete fire alarm system configuration.
Red FIRE Wall-Mount Design
The Siemens SLHSWR-F S54329-F22-A1 is specifically identified by Siemens as a wall-mounted horn-strobe with a clear strobe lens, red faceplate, and FIRE lettering.
The red housing provides traditional fire alarm identification, while the low-profile construction helps the appliance fit neatly into commercial building interiors.
Commercial Fire Alarm Applications
The Siemens SLHSWR-F can support audible and visual notification in offices, schools, healthcare facilities, hotels, apartment common areas, commercial buildings, institutional facilities, and other properties equipped with compatible fire alarm systems.
Its selectable candela and horn options make it particularly useful in projects where different notification levels are required while maintaining a consistent device appearance.
System Compatibility
Before installing the Siemens SLHSWR-F, technicians should verify notification appliance circuit voltage, available current, synchronization requirements, selected candela output, and compatibility with the specific fire alarm control equipment.
Siemens lists the SLHSWR-F S54329-F22-A1 as a UL wall-mount horn-strobe model with FIRE lettering. Qualified fire alarm professionals should configure and test the appliance according to the approved system design, applicable codes, and Siemens technical documentation.
Overall, the Siemens SLHSWR-F Red Wall Horn Strobe P/N S54329-F22-A1 provides reliable audible and visual notification with selectable horn and candela settings. Its red FIRE housing, energy-efficient LED strobe, and flexible configuration make it a practical choice for compatible indoor fire alarm systems.
