Yes or no. Sounder volume can be adjusted on an ADT galaxy panel.

Obviously very much preference and no absolute answer, but any input on the following would be useful.

• Should I rip out the current wired sensors, or can I re-use them? I like the idea of not touching working sensors and wires that all run back to a central location. However, if the recommendation is put in new sensors at the same time as a new panel, then I will
• Is the scantronic ion 40 best choice for me? Are there any other panels I should consider? My previous home had pyronix enforcer (all wireless) and that was nice modern system
• If I was to install the ion 40, or an enforcer, could I DIY it? I'm fairly comptent with computing, and basic electrics and CCTV, but I've never installed an alarm panel previously. Is one more DIY friendly than the other, and can I do it without specialised tools/software which I'll likely not be able to get hands on
• Finally, any panels that have free remote notifications (via internet)? The pyronix had an annual app charge which if I can save on, would be nice

So any advice and recommendations welcome.

Ion40 app is still free I think , pretty sure you can setup your own account , give it a go

If choosing over enforcer then any wireless alarm will do right ?
