The AMS Kombi:Alarm and Kombi:Alarm-Compact are fully automatic self contained alarm systems manufactured using complete semiconductor electronics. There are no replaceable parts or user adjustments. The units are designed for connection to a 12 volt DC (-10 to + 20%) supply.

The instruments are equipped with a very special proven sensor which allows the units to function as both Gas Alarm and Sleeping Gas Alarm systems.

The Kombi:Alarm has been specifically designed to allow up to two extra sensors to be connected where the size of the vehicle requires. It is recommended that a second sensor be fitted to vehicles exceeding seven metres in length. CO (Carbon Monoxide) sensor can be fitted as sensor two or sensor three on the KombiAlarm central processing unit. There is also a relay output available to connect an external flashing light or siren etc.
