The Spreest wireless alarm siren is an advanced alarm device ideal for protecting homes, shops, warehouses, and other facilities. Thanks to wireless communication and a built-in battery, the siren offers flexibility and ease of installation.
Wireless sirens eliminate the need for running cables to connect to the central unit, making it easy to install anywhere with power. It works with Spreest alarm systems available in our offer, including the H700, H501 , and other GSM and Wi-Fi alarms operating at a frequency of 433 MHz. To activate the alarm, the siren must be wirelessly paired with the alarm system via a 433 MHz frequency.
The siren is powered by a constant 100~240V power supply via the included adapter. In the event of a power outage, it has a rechargeable 400mAh battery, allowing the siren to operate even during power outages.
