Installation Instructions

1. Installation location: (see Figure 1)

Install the detector at a suitable location within a radius of (2-4) meters from the air source, within a range of 30cm from the ceiling.

#Do not install in high temperature and humid places.

#Do not install it near smoke exhaust pipes or chimneys.

#Try to avoid oil fume and steam pollution as much as possible.

#Avoid installing in windows or passages with high wind speeds.

2. Installation method:

After selecting the installation location, first install the hanging board on the wall, and then fix the detector to the hanging board. The detector should be installed firmly and not tilted. If the wall is a smooth surface such as tiles or glass, the wall at the installation location can be cleaned and fixed using the 3M adhesive in the product packaging; Ordinary walls require drilling holes on the wall and fixing them with plastic expansion bolts.
