The product has passed fire-protection equipment inspection. A microchip samples in real time and processes the data to calculate smoke density.

Compensates for drift from dust accumulation, temperature and humidity, and detects sensor faults (fault information is reported to the control panel)

Non-polarized conventional photoelectric smoke detector
The non-polarized detector contacts make installation of the fire alarm system very convenient.
The detector's circuit board has a 3-layer waterproof, corrosion-resistant coating, so it works well in damp and marine environments.
Light weight: 75g
Contacts made of 304 stainless steel, durable in hot and humid weather such as Vietnam's and suitable for installation in coastal areas.
Very low monitoring current, below 50 µA; alarm current 1–20 mA.
Works well up to an installation height of 12m; protection area per the applicable design codes and standards (in Vietnam: TCVN 5738:2021).
Compact, modern and attractive shape: diameter 105mm, height 43mm
Housing made of high-grade ABS plastic.
