The XENA XA401 Zone Alarm uses passive infrared sensors to detect motion across 20ft. (6m), bundled with a remote external unit that extends the volume output with a 135 dB siren.
Easy to install: simply mount, insert batteries and programme with your own four-digit security code. Connect the external siren to the base unit with the 10m (30ft.) cable provided. Once connected, both sirens will sound if the base unit's sensors are triggered or the connection is tampered with.
