The Moes ZSS-LO-SLA-U is a ZigBee-based smart alarm designed to provide both audible and visual notifications for your home security or automation system. It connects via a required ZigBee gateway using a 2.4 GHz wireless frequency, offering a reliable signal range of up to 55 meters. To ensure it stays active during power outages, the device runs on a 5V/1A USB power supply but includes a backup system powered by two CR123A batteries. When triggered, the alarm produces a flashing strobe light and a sound level reaching 90 dB at a distance of one meter, making it easy to notice even in noisy environments. You can customize the experience through the Tuya Smart Life app by choosing from 18 different alert sounds and adjusting the alarm duration anywhere from 0 to 1800 seconds. Constructed from white ABS and PC materials, this compact unit measures 68 x 68 x 32 mm and weighs only 65 g, allowing it to blend discreetly into most rooms. It operates effectively in temperatures between 0°C and 50°C, making it a practical choice for users who want a versatile, integrated warning system for their smart home.
