1. General Introduction to Chungmei Photoelectric Smoke Detector

1.1 Product Description

The Chungmei photoelectric smoke detector operates based on the principle of photoelectric sensing.
It is a device that is activated quickly, accurately, and reliably without false alarms caused by chemicals, exhaust gases, wind, or external light.

1.2 Advantages of Chungmei Photoelectric Smoke Detector

With the photoelectric sensing principle, the device is activated quickly, accurately, and reliably without false alarms from chemicals, exhaust gases, wind, or external light.
The 0.5mm stainless steel mesh prevents insects and dust particles while allowing smoke to pass through.
It is harmless to humans and animals as it does not use any radiation.
Due to its compact design and good outline, the product is very suitable for modern buildings and can be used in fine decorative ceiling designs.
The non-polarized connection prevents installation errors.
Photoelectric detectors ensure repeated use and can be easily maintained by removing the cover.

2. Operating Principle

The Chungmei photoelectric smoke detector operates based on the principle of photoelectric sensing.
When a fire breaks out and smoke enters the tightly sealed light chamber, smoke particles scatter infrared light, which then disperses into the receiving elements, generating a current. When the current reaches a fixed level, the fire alarm is activated.
This is a significant advancement recognized by science as a very quick and accurate way to activate early fire alarm systems.
Due to its sleek and compact design, it is most suitable for the interior decoration of modern buildings.
