this is a bit of a noob question but what's the difference between an internal sounder and an extension speaker?

 

 

A speaker is a speaker, ie needs a speaker signal. A sounder needs switched voltage (in our case 12v) to sound. 

Apart from the electrical connections being different they have slightly different applications.

A speaker will mimic all the noises the panel makes, if you have a good panel you can program volumes etc. Sounder is just a loud noise typically only in alarm conditions but would depend on output programming.

So really for a modern alarm, say texecom or orisec you want a speaker so you can use the different tones for fire, intruder etc?

The speaker is mostly so you know its set from outside the final door

agreed. I prefer sounders than speakers personally, hi-lo's particularly 

I am the opposite, I prefer the flexibility of speakers via panel programming.

Speakers are use to amplify any sounds from the control panel or keypad such as entry exit tones & chimes where a sounder will just make a noise when power is applied like a external bell box
