Alarm
Switching on the MSG150 in combination with the MS660 or DVS90
➤ Switch the MS660 or DVS90 alarm system on as usual:
On the remote control of the respective device, press
– the lower button (MS660)
– the NO button of the vehicle or additional hand transmitter (DVS90).
✓ An acoustic signal sounds and the green LED (fig. 8 1, page 5) flashes for approx. 10 minutes.
During this time the gas detector conducts a system test and the sensor is brought to operating
temperature.
If an alarm occurs, an acoustic signal sounds over the internal siren and the red LED (fig. 8 3,
page 5) glows. The internal relay sends an earth signal to the alarm input of the external alarm
system. The external alarm system immediately triggers an external alarm using the vehicle
indicators and the vehicle horn or siren.
➤ To interrupt the internal alarm, press the pushbutton (fig. 8 4, page 5).
➤ To deactivate the external alarm, press the following on the remote control of the respective
device:
– The top button (MS660)
– The NC button of the vehicle or additional hand transmitter (DVS90).

Alarm
If an alarm is signalled, proceed as follows:
➤ Determine the cause of the alarm immediately.
➤ Instruct children and anybody still asleep to leave the vehicle or boat.
➤ Open all doors and windows as quickly as possible.
➤ Avoid striking matches or any naked flames and turn off any sources of combustion
immediately.
➤ Turn off all gas-powered devices.
➤ Avoid causing sparks (do not use any electrical switches).
➤ Rectify the cause or leave the vehicle or the boat.
False alarm
For your safety, the gas detector is set to be very sensitive. For this reason the sensor also reacts to
other gaseous media. Using aerosols (e.g. propellants in spray cans) or thick tobacco smoke,
heavy alcohol fumes or steam arising from cooking can trigger an alarm even though no gas or
anaesthetic gas is present.
