I'm installing an Elk M1G system and am trying to determine interior speakers configuration. I need your help on best practices.
Exterior Sound. I am mounting an Elk siren in a stainless enclosureon the front of the house high under a gable.
Interior Sound. Our single-floor ranch house is 1,800 sq. ft., so I'm thinking three speakers should be sufficient: one speaker in the Living Room at one end of the house; one in the entry hall by the Keypad in the middle of the house; and one in the hall where three BR doors come together at the far end of the house. The speakers would be about 20 ft. apart.
I like the idea of a listen-in capability to check on things while we are away. So I need your advice on:

I like the idea of a listen-in capability to check on things while we are away. So I need your advice on:
- Should I use plain SP12 speakers and separate microphones or the M1TWSF with built-in microphones?
- Which listen-in interface board should I use, the unamplified M1TWI or the amplified M1TWA? What are the pros and cons of each? The price difference isn't very high, so I can go either way. Is the amplifier for the speaker output? Or the microphone input?
- Wire the attic speaker in parallel with the exterior siren on Output 2? Can I combine siren and speaker on Output 2?
- Pull the M120 out of the attic entirely and depend on the interior speakers?
- Replace the attic M120 speaker with a siren identical to the exterior siren? (from what I've read, it sounds like I cannot combine the M120 speaker and the exterior stainless siren on Output 2 anyway.)
-
For the interior, should I just use the speakers to alert any intruders and listen-in? Or should I add another sound source such as GE Piezo Screamers run off Output 3 driving a relay (suggested by WorkToPlay 3/7/11 at New Elk M1G Install - Speakers (#9).
