System Sensor SPSCWLED-SP Ceiling Speaker Strobe (Spanish)

The System Sensor SPSCWLED-SP FUEGO Ceiling LED Speaker Strobe is a white, ceiling-mounted emergency voice and visual notification appliance from the System Sensor L-Series LED product family. It integrates a high-performance speaker with an energy-efficient LED strobe and is specifically marked FUEGO for Spanish-language fire alarm applications. Honeywell identifies the SPSCWLED-SP as a 2-wire, white ceiling speaker strobe with FUEGO marking.

The appliance provides seven field-selectable candela settings, supports both 25 VRMS and 70.7 VRMS speaker operation, and includes four selectable speaker power taps from ¼ to 2 watts. Its LED strobe technology reduces current draw compared to xenon-based devices, while its plug-in mounting system, rotary configuration switches, and built-in diagnostic test points simplify installation, commissioning, and maintenance.

FUEGO Identification

The “-SP” suffix designates the Spanish FUEGO version of the SPSCWLED ceiling speaker strobe.

System Sensor documentation defines “-SP” models as FUEGO-marked devices, indicating Spanish-language fire alarm identification.

Model designation:
SPSCWLED-SP — 2-Wire LED Speaker Strobe, White, Ceiling, FUEGO

This makes the device suitable for installations requiring bilingual or Spanish-labeled life-safety notification appliances.

LED Strobe Technology

The SPSCWLED-SP uses LED-based visual notification technology instead of traditional xenon flash tubes.

Key advantages include:

• Lower current draw per appliance
• Reduced NAC loading
• Improved circuit efficiency
• Increased number of devices per circuit
• Reduced voltage drop across long runs
• Lower demand on auxiliary power supplies

The LED design also maintains consistent appearance across the System Sensor L-Series product line.

Selectable Candela

The SPSCWLED-SP provides seven field-selectable ceiling candela settings:

• 15 cd
• 30 cd
• 75 cd
• 95 cd
• 115 cd
• 150 cd
• 177 cd

Candela selection is made using a rotary switch on the device.

Proper selection should be based on:

• Ceiling height
• Room size and geometry
• Required visual coverage
• Applicable codes and standards
• System voltage and circuit loading

Dual-Voltage Speaker Operation

The speaker supports two standard fire alarm audio voltages:

• 25 VRMS
• 70.7 VRMS

This allows compatibility with most distributed fire alarm voice evacuation systems.

The selected voltage must match the connected fire alarm voice amplifier output.

Selectable Speaker Power

The SPSCWLED-SP includes four speaker tap settings:

• ¼ watt
• ½ watt
• 1 watt
• 2 watts

Higher wattage increases sound output but also increases amplifier load. Selection should be based on:

• Required audibility
• Ambient noise level
• Speaker spacing
• System amplifier capacity
• Voice intelligibility requirements

Emergency Voice Performance

The speaker is designed for high-fidelity emergency voice reproduction with low distortion.

Typical system uses include:

• Fire evacuation instructions
• Emergency voice announcements
• Relocation messaging
• Alert tones
• Mass notification messages
• Emergency communication instructions

All audio content is generated by the connected fire alarm voice evacuation system.

520 Hz Tone Capability

The SPSCWLED-SP can reproduce a 520 Hz ±10% square-wave tone when driven by a compatible fire alarm control panel.

This function depends on the external system; the speaker does not generate tones independently.

System Sensor Synchronization

The device supports System Sensor Sync protocol for coordinated flashing of compatible visual appliances.

Synchronization may be provided by:

• Compatible UL-listed power supplies
• System Sensor synchronization modules (e.g., MDL3)
• Compatible fire alarm control panels

This ensures uniform flash timing across multiple devices in the same field of view.

DVM Diagnostic Test Points

The SPSCWLED-SP includes Digital Voltage Meter (DVM) test points on the face of the device.

These allow technicians to:

• Measure operating voltage without removal
• Perform end-of-line testing
• Troubleshoot NAC issues
• Verify voltage drop during commissioning
• Speed up inspection and maintenance

Plug-In Mounting System

The L-Series design uses a plug-in mounting plate system.

Features include:

• Pre-wiring of mounting plate before device installation
• Integrated shorting springs for continuity testing
• Protection of device during construction
• Fast final installation of speaker strobe head

This reduces installation time and improves system reliability during construction phases.

Legacy Compatibility

The SPSCWLED-SP is electrically compatible (within listed limits) with:

• SpectrAlert systems
• SpectrAlert Advance systems
• L-Series systems

This supports retrofit and system expansion applications, subject to control panel and power supply compatibility.
