Hi, I found this site while searching for information on the correct way to add a second bell box to my system.

The original control panel has died and i have replaced it with a Texecom R8 control panel. The bell boxes are AG6, i have been unable to find a wiring diagram and whilst searching i have also seen several refences suggesting that the second box is SCB but do not really understand how i would do this.

I would appreciate your guidance on this, Thank you

Hi and welcome

Some boxes can't do this in which case you need another power supply.

Hope this helps....

 

panel.         bell

+12v           hold off +

0v.              hold off -

bell.            TRIG

Strb.           STB

Tamp.         RTN

 

 

Both boxes can stay as they are, because AG6s sound off their own batteries, No SCB mode required.

do they, didnt know that. Most bells as SAB meaning they do draw from the panel. Id be checking the current in alarm to see if the panel can handle it

Don't fit them but looking at the datasheet with 350mA current I would suggest to check this.

I did think similar, but I dont really know Texe stuff. And I can never understand why people want two bells in the first place. I dont have one on my house let alone two nothing more annoying than a sounder going off on a lovely summers day, and nobody takes any notice apart from complaining about the noise.

Depends on the house for me, i have no issue with two.

However, I would sooner have a single of decent stuff instead of multiple of budget stuff.

Same as PJ, we do have a sounder on the front but it went faulty about 10 years ago and I have never bothered replacing it.

No man totally wrong ag6 doesn't have scb mode in anyway hence it will eventually kill the panel
