Recently I installed a VM130 module to switch on a 2 zone alarm in a motorhome. Channel 1 switches zone 1 on and off, channel 2 switches zone 2 on and off. I set both channels to the “ON/OFF” mode but after several hours channel 1 switches itself OFF automatically. Last year I installed several VM108/109 setups and these still work without any problems. I’ve tried all different mode’s on the VM130, but channel 1 keeps switching OFF after some time in the ON/OFF mode. The module has already been replaced but the problem remains the same. It 's even been tried without the alarm print connected so that only the VM130 is connected. The first installed VM130 also had very low reception. The transmitter had to be as close as 1 meter to be able to set any channel ON or OFF. This was resolved with placing a new module, but the switching OFF problem remains.
