I am new to this game and adding a rear bell box to an existing alarm system, do I need to connect the tamper return to the front box or can it go straight to the control panel ???

what sounders are you using?

Lookig at the Melcom engineers manual this week, I noticed there are two tamper feeds and return for 2 bellboxes.

The alarm sounder is a Texecom, and the instructions say connect the second bell to the first so they are in series.

If I connect the second bell straght to the -Ve Tamper return on the control pannel, (both bells will be in parallel) and the rear tamper is activated will this bell sound only ?? and vise versa..

also I have a 12volt internal sounder on the system, this is connected to the +Ve, -Ve and the -Ve sounder trigger for the external sounder. If the tamper was activated say on the rear box would this internal sounder activate.
