Mate MT-WSD02 Wireless Photoelectric Smoke Detector

The Mate MT-WSD02 is a wireless photoelectric smoke detector designed for fast and reliable fire detection in residential and commercial environments. Featuring a 360° smoke intake design, dual optical smoke detection, 85 dB built-in siren, wireless alarm transmission, dual CR123A lithium batteries, and up to 5 years of battery life, it delivers dependable fire protection with advanced false alarm reduction.

Mate MT-WSD02 Wireless Photoelectric Smoke Detector

The Mate MT-WSD02 is a next-generation wireless smoke detector developed to provide rapid and accurate fire detection while minimizing false alarms.

Its innovative 360° air convection smoke chamber allows smoke to enter from every direction, enabling faster detection than conventional smoke detectors. The detector also features a dual optical scattering chamber, providing more reliable smoke analysis and improved alarm accuracy.

When smoke reaches the alarm threshold, the detector immediately activates its 85 dB built-in siren while simultaneously transmitting a wireless alarm signal to the alarm control panel.

Powered by two CR123A lithium batteries, the MT-WSD02 offers ultra-low power consumption and a battery life of up to 5 years, making it ideal for long-term residential and commercial fire protection.

360° Smoke Detection

The MT-WSD02 features a 360-degree smoke intake chamber, allowing smoke to enter from all directions.

This airflow design enables faster detection and quicker alarm activation during the early stages of a fire.


Dual Optical Detection Technology

The detector uses a dual optical smoke detection chamber that analyzes smoke from multiple directions.

This advanced design improves detection accuracy while reducing nuisance alarms caused by dust or environmental interference.


Reliable Fire Protection

When smoke reaches the alarm threshold, the detector immediately:

  • Activates the built-in 85 dB siren
  • Flashes the LED alarm indicator
  • Sends a wireless alarm signal to the alarm control panel

This ensures rapid warning for both occupants and connected alarm systems.


Intelligent Self-Monitoring

The detector continuously monitors its operating status and automatically reports important events.

Functions include:

  • Self-test
  • Test/Reset button
  • Low battery warning
  • Alarm status indication
  • Fault indication
  • Normal operating status monitoring

Long Battery Life

Powered by 2 × CR123A lithium batteries, the MT-WSD02 uses an ultra-low-power CMOS processor to achieve an operating life of approximately 3–5 years, reducing maintenance requirements.
