Description

Siemens SL2SPSCW-F Ceiling Speaker Strobe

The Siemens SL2SPSCW-F is part of the “SL2” series from Siemens (High-Fidelity Speakers & Speaker-Strobes). This unit combines a speaker for audible notification and an LED strobe for visual alerting in a single appliance, designed for ceiling-mount applications in indoor fire and mass notification systems. Its modern form factor and high-fidelity speaker make it ideal where voice and tone signalling is required, in addition to visible alerting.

Key Features & Benefits

• Integrated Speaker + Strobe: Combines audible output (speaker) and visual output (strobe) in one device, reducing appliance count and simplifying wiring.

• High-Fidelity Speaker: Wide frequency response (~300-8000 Hz) supports voice communication as well as standard fire tones.

• LED Strobe Technology: Lower current draw compared to older xenon strobe units, enabling more devices per notification appliance circuit (NAC) and reducing power supply burden.

• Field-Selectable Settings:

  • Candela settings for the ceiling mount: 15 cd, 30 cd, 75 cd, 110 cd, 150 cd, also 177 cd.

  • Speaker wattage taps: 1/8 W, 1/4 W, 1/2 W, 1 W, 2 W, 4 W, 8 W (depending on voltage setting) for flexible coverage in varying ambient noise environments.

• Dual Voltage Speaker Line: Compatible with 25 Vrms or 70.7 Vrms speaker line voltages (depending on model) for integration into common fire-alarm speaker circuits.

• Pre-wiring/Pre-testing Mounting Plate: Simplifies installation with in/out terminals and also allows wiring ahead of device mounting.

• Ceiling Mount Design with White Housing & “FIRE” Marking: The “CW-F” in the model denotes Ceiling (C), White housing (W), and “FIRE” legend (F) for life-safety identification.
