Replacing battery without alarm going off

[halcyon]

Hi, had a quick look but couldn't find an answer to this.

Let the battery in my VY Executive run flat recently. As soon as I connected the jumper cables to get it going, the alarm went off.

I've now removed the battery and charged it, but when reinstalling it, am I going to set the alarm off as soon as the leads contact the posts? Do I need to stand there like an idiot reattaching them while the alarm is going off, or do I start up the engine while the leads are dangling off the battery?

Advice appreciated!

as soon as the alarm starts going off, unlock the car using the remote.

Just pull the horn fuse if concerned.
