BRK SLED177A Hardwired LED Smart Strobe: Life-Saving Visual Alerts for 100% Home Safety
The BRK SLED177A is a 120V AC wire-in 177 candela LED strobe light designed to provide a visual alert for hearing-impaired occupants when connected to compatible smoke, heat, or carbon monoxide alarms.
Built for residential and institutional environments, it uses distinct flash patterns to indicate different alarm conditions and supports interconnection with multiple devices.
Protect your loved ones with a safety system that leaves nothing to chance.
For family members who are Deaf or hard-of-hearing, standard audible alarms aren't enough—especially during the night.
The BRK SLED177A is a professional-grade, 177-candela LED strobe light designed to provide clear, high-intensity visual warnings that cut through the darkness, ensuring everyone in your home has the vital seconds they need to evacuate safely.
High-Intensity Visibility: Professional Protection for the Hearing Impaired
Standard indicators can be easily missed, but the 177-candela LED strobe is designed for maximum impact.
This high-intensity light is powerful enough to wake sleeping residents, delivering a clear signal that an emergency is occurring.
By choosing the SLED177A, you are investing in a dedicated safety accessory that meets the most rigorous visible signaling standards.
- 177 Candela LED Strobe: Delivers an ultra-bright, high-intensity flash that provides maximum visibility in every corner of the room.
- Slim, Low-Profile Design: At nearly half the size of older strobe units, this model blends seamlessly into your modern home décor without sacrificing power.
- 10-Year Manufacturer Warranty: Enjoy a decade of peace of mind with a product built for reliability and long-term durability.
Smart Interconnect Technology: Instantly Distinguish Between Fire and CO
One of the biggest challenges in home safety is knowing exactly what the danger is without looking at a screen.
The BRK SLED177A features "Smart Interconnect" technology, which allows it to flash in distinct patterns depending on what your interconnected alarms detect.
This ensures you react correctly to a fire versus a carbon monoxide leak.
- Smoke & Heat Warning: Produces a constant flash (approximately 1 per second) to signal an immediate fire or heat threat.
- Carbon Monoxide Warning: Produces an intermittent flash (4 flashes, then a 5-second pause) so you know exactly when to clear the home due to CO.
- Synchronization and Precision: When multiple strobes are installed, they flash in perfect unison, preventing confusion and maintaining a clear signaling path throughout your household.
- LED Smart Strobe, ADA hearing impaired strobe light for both Smoke and CO, Half the size of standard strobe alarms, Designed to provide hearing impaired individuals with a visual warning of a fire or a carbon monoxide danger when used with smoke, heat or carbon monoxide alarms

What does the BRK SLED177A do?
The BRK SLED177A is a hardwired LED strobe light that provides a visual alert for hearing-impaired individuals when triggered by interconnected smoke, heat, or carbon monoxide alarms.
How does the strobe indicate different types of alarms?
It uses distinct flash patterns—a steady pattern for smoke/heat events and an intermittent pattern for carbon monoxide alerts.
Is this device standalone?
No. It must be interconnected with compatible BRK or First Alert smoke, heat, or CO alarms to function as an alert system.
How many devices can be connected in one system?
The unit supports up to 18 interconnected devices, with a maximum of 12 smoke alarms within that system.
What type of installation does it require?
The SLED177A is a 120V AC wire-in device that mounts to a standard electrical box and supports both ceiling and wall installation.
Is this a standalone smoke detector?
No. This is a visual signaling accessory. To function, it must be hardwire-interconnected with a compatible BRK or First Alert smoke, heat, or CO alarm.
Does it require a battery backup?
The SLED177A is a 120V hardwired device. It relies on your home's AC power to trigger the high-intensity strobe, ensuring it always has the current required for a 177-candela output.
Is it easy to test?
Yes. Simply press the "Test" button on any of your interconnected smoke or CO alarms. The SLED177A will immediately begin flashing in the pattern corresponding to that alarm type.
Does it flash differently for Fire vs Carbon Monoxide?
Yes! This "Smart Strobe" technology uses a constant flash for fire and an intermittent flash for CO, allowing you to react appropriately without checking the alarm face.
