Just wondering as I've not come across this before.
Also included with my replacement speaker unit was a 160Ω resistor at the 3-terminal choc block on the speaker wires.
Why? Who uses a 160Ω resistor with their 16Ω speaker (in an alarm environment) ?
The external speaker (16Ω) is a familar white plastic boxed affair to replace a remote one I'd fitted (an old PC speaker that I thought was robust enough - it lasted a few years). It was just a matter of tidy wiring and different mounting holes and was quickly fitted.
