PST Wi-Fi Smoke Detector

Protect your home, apartment, villa, office or commercial premises with the PST YG400A Smart Life Wi-Fi Smoke Detector. This compact photoelectric smoke alarm continuously monitors the surrounding area for smoke and provides an immediate local audible alarm, flashing red warning light and smartphone notification when smoke is detected.

The detector connects directly to a 2.4 GHz Wi-Fi network, eliminating the need for a separate smart-home gateway or hub. Through the Smart Life app, users can receive real-time smoke alerts, check device status, monitor low-battery warnings and share access with authorised family members.

Its ceiling-mounted design, approximately 20 m² coverage and battery-powered operation make it suitable for indoor areas such as bedrooms, living rooms, hallways, offices, shops, restaurants, schools and storage areas.
