Aritech Cs350

Hi

The alarm control panel in my parents house makes an intermittent buzzing or humming noise. It's quite faint, like a transformer noise, but it changes volume. Trouble is the panel is in a cupboard in the hall but on a wall that has their bedroom on the other side. This amplifies the noise.

They never us the alarm so my dad just switched it off. But after about 10m the low battery warning came on and the alarm sounded. So he had to switch it on again.

Firstly, how can I switch it off completely? And then how can I fix it?

Thanks for any help

The fact that your system activates 10 mins after power failure indicates that the battery in the panel needs replacing, also when a battery ages it tends to draw excessive charging current which can make the transformer hum much more loudly than normal.

Replace the battery as a first move.

i agree ,excessive draw from faulty bat tends to rev up the transformer how ever i did come across a few aritechs that had loose transformers ( not as bad as texecom though ) problem is to fix this and a new bat you need to go into the panel which i would advise against ,not only is there live parts if the tamper reset has been set to engineer then you wont be able to do anything ,my advise is to call a local nsi or ssaib company to check it out .
