Description
The HEIMAN Indoor Siren Zigbee is a sleek, modern indoor security siren designed to integrate seamlessly into your smart home setup. You simply plug it into a standard Type C power socket and pair it over Zigbee 3.0, enabling it to react instantly when a connected sensor triggers. With a powerful alarm sound reaching up to 95 dB and a bright red LED flash, it ensures audible and visible alerts for break-ins, fire or water-damage events. The built-in backup battery keeps the siren operational even when mains power is cut or the plug is removed, offering that extra layer of protection and peace of mind.
Thanks to its compact design and Plug & Play installation, the unit is ideal for retrofitting into existing homes or integrating into new smart-home installations with minimal effort.
