Guard plug is the easiest way to secure the doors of the motor-home cab. When the Guard Plug is plugged in, the alarm is sounded when either of the cab doors are opened. All doors which activate the interior light when opened, will trigger the alarm. Alarm sounds at approx. 93dB (int. siren).

*Some of the latest cabs give no power to the ignition when key is in the “off position”, under these circumstances the Guard Plug can only be used if the cabs wiring is altered.
