## Questions & Answers

**Q: How loud is the alarm?**
A: Dear Rahul, 

Thank you for asking this question. 
The detector has a Sounder Output of 80dB @ 3 Meter. 

To help you better understand the sound output, here are some examples of 80db levels, imagine yourself 3 meters from them:
- A window air conditioner
- A food blender or a garbage disposal
- A hairdryer
- A ringing telephone

Hope this helps. 
Thank you for thinking about Safety, Security & Automation solutions for yourself and your surroundings.

**Q: Is it a fire detector alarm too?**
A: Dear Dev D.,

KTI Battery Operated stand alone smoke detector, adapting optical
chamber, to detect smoke produced by fire, gives high volume
sound notification in case of alarm. It is suitable for small projects
like home application, small shop, pub, etc. The S-9102R provides a polarized N/O contact output (photoelectrical isolated) for further application. 

Thank You,
KTI E-Commerce Team.

**Q: Does it contains any radioactive isotope?**
A: Dear Francis,
This standalone smoke detector does NOT contain any radioactive isotopes. 
It uses optical smoke sensing parts and art of state production technologies to make your environment safer.  
The technology has no harmful parts. 

Team KTI.

**Q: Range of detection?**
A: Thank you for asking this question. 
So basically, the ideal range for this detector is approximately 40 square meters. 
Ideally, the smoke detector covers a circular area with a 3.5-meter radius or a 7-meter diameter. 

Although, there are other factors that affect its capabilities, mainly the wind flow direction. So as long as the smoke is able to flow easily into the detector, the detection would be speedy and can even cover more area.
