Alarm--What is it?

[cjthies]

Last evening we moved our 2008 Jay Flight G2 from our driveway to a more permanent location that had been prepared for it. It had been plugged in to shore power for a few days. So, I unplugged, we moved it and started to level it (which was easy because the site was pretty level). Immediately I heard from inside the TT a high pitched alarm. So, I went inside and checked around. I flipped the main breaker and plugged back in to shore power (a 30 amp 120 outlet). Then the alarm stopped. What was that ? I did not smell anything so didn't think it was LP. Can anyone enlighten me? It scared me, of course, because I didn't know where it was coming from.
Thanks.

It could only be one of 2 things.
Lp/c02 or a smoke detector. I'm betting on the LP/CO2 cause it uses 12v. I would check your battery charge. Low voltage will trigger it.

Sometimes the LP alarm will sound if the battery is low and since you unplugged the converter was not connected.

When I plug in our Skylark I hear a beep inside the trailer as the power is applied. It is just a beep not a long drawn out tone.

Low batteries, guaranteed.
