The Firesco ZR153SW-CB standalone smoke detector uses an optical sensor and activates a red indicator light and an 85 dB siren at a distance of 3 m when smoke is detected. It connects via Wi-Fi to Tuya/Smart Life and sends real-time notifications, while also operating without the app. The Test/Silence button lets you test the functions and silence the alarm, while the detector indicates faults and a drop in supply voltage.

It is powered by one replaceable 3 V CR123A lithium battery and continues to provide protection in the event of a power outage. Its housing is made of fire-retardant plastic and complies with the EN 14604:2005/AC:2008 standard. The package includes the battery, mounting base, mounting pins and a user manual in Polish.
