I have a novagard 4 bell box with one piezo in it as standard , could i splice into the wires and wire on a another piezo to give it that extra bit of kick, or should i wire the the extra piezo as follows

New piezo BB Connection

Red Wire (+) Hold off +
Black Wire (-) Siren Trig Neg (+)





Thanks in advance

NO
wire the new piezo with the existing piezo connections, as they are a passive device not an active one!

if you wire it as you say you will cook it!

In the bell box there is a little plug which plugs onto the pcb of the sab. The plug has + and - and tamper1 and tamper 2 . Would it be ok to add another piezo or would it damage the pcb?

It was a joke, you know a ........never mind.

Yes, from the p1ss poor picture it looks correct.

Drop the battery in and see. Thats a test, not a joke!

Can i ask how to protect from oxidising inside a bell box?

a few peoples i have done ive had to strip allot of the sheath due to oxidisation.
 
You will always get condensation in there and oxidation eventually.
Some non conductant would help, but can cause issues if having to remake connections.
As before keep conductors as short as possible. Tape the terminal block and use the cover for the terminations...................thinking about it does the nova have a clear cover like the Texecoms? It does not does it. Hmmmm

Personally I leave a lot of spare inside sounder backplate, just in case. Same as a bit of spare behind the PIR (well hidden of course).
