PowerMaster 33 G2 and ADT Elmdene 7422-G3F siren

MP1 · 22 Feb 2020

Hi all,

I was wondering if someone could help me.

I have a Visonic PowerMaster 33 G2 alarm system installed at home without any expander. I also have Elmdene 7422-G3F external siren (ADT branded). I would like to use it with my alarm system. I have two questions:

- What expander would I have to buy for my alarm
- How do I wire the external siren to my alarm system

I attached a photo of the siren.

Any help would be much appreciated.
