With PLACE, you get:
- Industry-leading technology
- Peace of mind knowing your home meets the latest safety standards

Why Low-Frequency Alarms Matter
According to studies from the Fire Protection Research Foundation, a 520 Hz square-wave tone is significantly more effective at waking:
- Children
- Older adults
- People with hearing impairments
- Those under the influence of alcohol or medications
Lower frequencies travel better through physical barriers like:
- Closed bedroom doors
- Thick walls
- Soft furnishings and carpets
Meets Modern Safety Standards
- PLACE devices meet or exceed the ANSI/UL 217 standard, which require:
- A sound level of ≥ 79 dBA at 10 feet
- A frequency that falls within the 520 Hz low-frequency range
How PLACE Uses Low-Frequency Sounders
PLACE devices use the low-frequency alert for all critical alarms:
- Smoke detection
- Carbon monoxide (CO) detection
- Heat detection (in the Garage model)
- Natural Gas detection (in the Kitchen model)
- In some cases, combined with voice alerts, ring light, and backlit icon visual cues
Testing is simple—just press the TEST button or use the PLACE app. We recommend weekly testing to ensure your system is always ready.
