changing battery on Guard Tec 350 alarm?

Hi

I am not sure so was going to change both. The problem i have is the system is over 15 years old. When i get a power cut the alarm goes off.

Am i right in saying it could be the battery in the control panel or the outside bell

thanks

External or internal?

Unless you have the "engineering" code you will get the internal for sure.

Doing it correctly you would expect the external to sound as well.
