How long as it been alerting you ?,my guess is for a while now.
Ok its telling you that the battery in zone three monitoring device (probably PIR) is now exhausted thus rendering it inactive.

When the battery is replaced and the signel restored,the fault should clear,

3.6v lithium (Tadiran TL-5902) lasts for years these.

OK,stick to one post here,it can get a little confusing if not.

You will probably find you cannot arm the system either,

press the `show ok`button and read the message,repeat the procedure untill you have read all the messages.

What do they say ?.
