Upon request, the transmitter can also be supplied with three integrated relays. This enables you to use it as an independent gas detection system with two arbitrarily adjustable concentration alarms and one fault alarm. Audible alarms, signal lights, or similar devices can be controlled locally without needing an additional cable between the transmitter and central controller.

The relays make the transmitter more independent.
