Deaf/Hard of Hearing (DHH) smoke alarms—often called “shakers”—are not stand-alone smoke detectors. Instead, they are alarm systems that work in conjunction with traditional smoke alarms to ensure that deaf or hard of hearing individuals are notified during fire emergencies.
Anka Security analyzes research information on these devices for you:
How They Work:
1. Connected to Smoke Alarms – These devices connect to a home’s existing smoke alarms (either wirelessly or via a strobe light).
2. Alarm Method – When a smoke alarm is triggered, a DHH system activates:
• Strong Vibration (Shaker) – A vibrating disc placed under a pillow or mattress wakes the person.
• High-Intensity Strobe Light – A bright flashing light provides a visual alert.
• Loud Low-Frequency Alarm – Some models emit a low-pitched sound that some people with normal hearing may feel or hear.
3. Critical for Safety – Because traditional alarms rely on high-pitched sounds that people with DHH may not be able to hear, these specialized devices can be lifesaving.
Key Features to Look for:
✔ Compatibility – Works with existing smoke/CO alarms.
✔ Multiple alarm modes – Vibration + strobe light + loud tone.
✔ Battery backup – Ensures functionality during power outages.
✔ Portable option – Perfect for travel or temporary accommodations.
