Dual zone Microwave - M20 (M24 requires SD2412)

Triggers your alarm if it detects any physical movement in or around your vehicle. The dual zone microwave sensors (radar) protect both the inside and outside of your vehicle when fitted to a suitable alarm system. An intrusion into the exterior zone will chirp the siren, whilst an intrusion into the interior zone will fully sound the siren. They are adjustable for zone field size. Certain alarms only permit single zone protection and this product should be used to protect the interior zone.
