Wireless indoor siren

Wireless indoor siren generates up to 105 dB at a distance of 1 m to deter burglars and attract the attention of neighbours in case of unauthorised trespassing. An inbuilt LED light and beeps indicate the system status. Moreover, the siren can power an external LED installed at the front door to warn that the property is armed.
