M20/M20S - M24 - M33


The M20/M20S is a very popular, easy to use, alarm system which includes an engine immobiliser and the ability to control your vehicles central locking..

This alarm system is wired to the bonnet, boot and doors and is supplied with a 2 stage shock sensor. Should an attempt at a break in occur, the M20/M20S determines the shock level and either gives pre-warning chirps or fully sounds the siren with indicators flash.

To provide greater security and peace of mind, the system will re-arm, re-immobilise and relock the doors (if connected) 30 seconds after it was disarmed but a door not opened.

The M20 is supplied with a standard siren and the M20S with a battery back-up siren.

The remote control can also be adapted to have the ignition key inserted - see photos.
