MSG150 Connecting the gas detector
15
Connecting the gas detector using the 12/24 Vg plug
➤ Insert the 12/24 Vg plug into a socket with a constant 12/24 Vg supply.
This socket should be connected with the vehicle battery.
✓ 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.
Connecting the gas detector so that it is hardwired
If you wish to give the gas detector a permanently wired connection and switch it on with the
RV-AMP-SW additional switch, please use the circuit diagram fig. 9, page 6.
➤ Disconnect the 12/24 Vg plug from the cable.
➤ Remove around 10 cm of the outer insulation on the end of the cable.
➤ Connect the black, yellow and orange cable to the bodywork earth (terminal 31).
➤ Connect the red cable to the output of the RV-AMP-SW additional switch.
➤ Connect the input of the switch with a 1 A fuse to the positive battery pole.
8.2 In combination with the external siren (ref. no. 9101600008)
If you wish to connect the gas detector with the external siren, please use the circuit diagram
fig. 0, page 6.
Mounting the external siren
The external siren can be mounted in the engine compartment.
When mounting it, ensure that the installation location is
• Not in an area exposed to splashing water
• Not near the exhaust system
• Cannot be accessed from underneath the vehicle, to ensure that it cannot be sabotaged.
➤ Mount the external siren with the acoustic horn facing downwards.
Connecting the alarm siren
I
➤ Connect the black cable of the siren to the bodywork earth (terminal 31).
➤ Connect the red cable of the siren to the relay contact 2 (fig. 3 2, page 4).
➤ Connect the relay contact 1 (fig. 3 1, page 4) to the 12 Vg continuous positive.
The cable must be fused with at least a 1 A fuse.
NOTE
If your vehicle does not have a 12 Vg continuous positive cable in the mounting area,
you can also connect the input to the vehicle battery using a 1 A fuse.
