KombiAlarm Narcotic Gas Alarms

The KOMBIALARM family is a Combined fully automatic LPG and Sleeping gas alarm warning system with specially designed built-in sensor and audio signaling units. All sensors are high quality 5 year life design.

The KOMBIALARM-COMPACT Single Sensor Unit is designed for vehicles up to approx. 7 meters in length where a single sensor unit is sufficient to detect any gas well before the gas becomes volatile or explosive.

The KOMBIALARM-Plus is designed for larger vehicles where additional remote sensors can be fitted and a switching relay allows for connection to a separate alarm or warning device (flashlight etc). Remote sensors are available in two versions, KO/LPG for the detection of LPG and Narcotic (KO-gas) and a CO sensor to detect carbon monoxide.

The KombiAlarms will detect the smallest concentration of sleeping gas before it renders the occupants unconscious.

Alarm thresholds are fully automated and set well below the level that the gases become volatile.

  • Low power consumption.
  • Operates from a standard 12 Volt DC supply.
  • Can be plugged into cigarette socket
  • For use in: Caravans, Motorhomes, Apartments, Boats & Lorry Cabs
