The Sample Application

l  Family

Ion type smoke detection method, compared with the photoelectric more sensitive, more sensitive, can effectively detect the area of 20 square meters, with alarm buzzer, alarm loudness can reach 85 db.Easy to install, sensitive, alarm volume enough to remind users at home.

l  School

In schools with dense students, photoelectric smoke sensors are installed to detect smoke and give an alarm in time. Teachers and students can evacuate safely as soon as possible to ensure the safety of teachers and students and the normal operation of facilities.


l  Warehouse 

For warehouses with different types of goods, smoke alarm can be installed to monitor the changes of the internal environment of the warehouse in real time, with sensitive induction and timely treatment.

l  Stores & Convenience Stores

Detect combustible gas to ensure the safety of goods in the store.
