Wireless security without the need for cables Chuang SPS-260 is a completely wireless siren, ideal for protecting yards, driveways, gardens and other outdoor areas. Thanks to the rechargeable battery powered by the solar panel, it provides reliable protection without additional costs for power supply or installation. Independent or integrated use The siren can function independently as a local alarm in combination with other devices on the same frequency, such as remote controls, contact sensors for doors and windows, as well as PIR motion detectors. It can also be connected to larger wireless alarm systems as an additional siren. Strong sound signaling The built-in siren produces a sound of up to 110 dB , which effectively deters potential burglars and attracts attention in the event of an incident.
