SW 1070 Panel Totally Non-Volatile?

[Eugene's DIY Den]

So I'm going to take my external sounder down off the wall to diagnose what's wrong with it. Maybe the piezo element is failing as james.wilson suggested in another post.

Are the settings stored indefinitely in non-volatile memory when I remove mains and battery power? I'm going to have to disconnect wires from the sounder, so I don't want the ends shorting out or have to put tape or whatever over them when I disconnect them. I suppose I could stick them one by one into a terminal block to keep them apart.

just snip them individually that way you will know what colour goes where when you put it back/replace it. No need to down power completely just be aware the alarm will tamper

I wrote the colours of the wires on the inside of the sounder enclosure and what terminals they connect to when I installed it, for scenarios like this. I notice when I open the lid of my panel, it detects the tamper and keeps beeping, but the alarm doesn't sound. Maybe I set it that way, or that's the default. The alarm sounds when the panel is armed and the lid is opened, as expected. Also I powered down the panel and disconnected its battery and the volume from the sounder was really low, suggesting the battery in it is pretty much dead (no LEDs lit either). When the battery in the panel is connected and also mains power, volume from the sounder is still scratchy and volume randomly increases and decreases, suggesting a secondary problem of a bad piezo element as you suggested or maybe corroded connections.

The time and date also reset on my wired keypad. So either they don't have a non-volatile memory to hold time settings or a lithium cell in the keypad is dead.

Watchdog reset or something? There's no battery in keypad

When you completely down-power It remembers the codes zone settings ect in the NVM. But it wont keep the clock going while its down powered,  that will default to watchdog

Of it's new firmware on apps it can be programmed to sync the clock to the cloud

It has to connect to the cloud first though. When its first powered up it doesnt know what day of the week it is let alone the right time. A bit like you when your alarm clock goes off on a Thursday morning after youve been down the pub the night before for pool night
