ELK SP12F: I know you can use this speaker for voice or alarm but can I use it for both.
ELK-M1TWSF: This is a two way listen in mic/speaker. Can I install one of this in each room or that is overdoing it? Also, do I have to install a keypad at every location I install this two way in?
ELK-74: This a speaker/siren. would anyone recommend me installing each of this in every room? Or would it be irritating as time goes on? Also, can I use this for voice application?
Also, for the ELK TEMP sensor, can I use a cat5e cable? If so, do I use double strand for the connections or a single strand of the cat5e cable?
