Smoke Detection

A Better Way to Design Smoke Detectors.
A Better Way to Save Lives.

Smoke detectors save lives. Three of every five fire-related deaths in the U.S. occurred in properties without smoke detectors. Smoke detectors save lives, but only when they are used properly. In properties with smoke detectors, nearly one in four deaths (23%) occurred where smoke detectors were not working, or were disabled due to frequent false alarms.

Smoke detector manufacturers face four critical challenges:

  1. Higher performance to reduce the frequency of false alarms, which result in consumers disabling or turning off the units
  2. New regulatory requirements (UL217, EN54/14604)
  3. Power consumption that requires frequent battery replacement
  4. Reducing smoke detector size to enable easier architectural integration and aesthetic appeal

New solutions for smoke detection

Leveraging our deep sensor expertise, we can provide integrated solutions to help manufacturers engineer better smoke detectors.

Performance

Performance

  • Our integrated design uses two colors to separate particle sizes, increasing the ability to detect and classify smoke types and reject nuisance sources in challenging environments, such as kitchens and bathrooms

Regulation

Regulation

  • The ADI module is engineered to help manufacturers meet UL217 requirements as well as EN54/14604 specifications.

Power

Power

  • The analog front end (AFE) and integrated design result in better power management to extend battery life, allow for sensors, and support wireless product designs

Size

Size

  • Integrating circuitry and components allows for a smaller, simplified chamber design to improve manufacturing flow efficiency. It also reduces calibration requirements at production test and assembly
  • Contributing to a smaller footprint allows for sensors, wireless connectivity options, and other added value features
  • Facilitating a compact design reduces system cost and results in a smaller, more aesthetically pleasing detector

How it works

Analog Devices offers a solution that combines an analog front-end, LED, and photodiode into a small package, greatly reducing the smoke detector footprint. The integration of the photodiode and AFE also provides high ambient light rejection and wide dynamic range to better reduce false alarms.


Analog Solution-Back Scattering
Common Solution-Forward Scattering

 

A back-scattering design can greatly reduce the overall size of the smoke detector.

The ADI solution also enables a back-scattering design with closer proximity of the LED to the photodiode. This reduces circuit board size and allows for smaller smoke detectors that are more architecturally compatible for residential and commercial use.
