The ELK looks pretty complex even to determine which components are needed. So my plan is to connect the ELK to ISY, use wireless door/window sensors. No motion detection. Preferably two sirens. I came up with the following items to buy. Does it look like a complete set to cover my needs?
ELK M1GSYS4S M1 Gold Kit. Includes the M1 Gold Board, M1KP2 LCD Keypad, enclosure, battery, transformer, ELK-73 Interior Speaker, two telephone protectors that I'm not planning to use. ELK M1XRFTW - Two Way Wireless Trasciever ELK M1XEP M1 ETHERNET PORT EXPANDER AND INTERFACE Door sensors. There are 2 options with ELK (didnt want to go with GE or honeywell). ELK-6020 seems the better option since it has the largest capacity battery. There is also ELK-6021 a slim model that is fed by CR2032 battery. ELK-6010 Two-Way Wireless 4-Button Keyfob Remote Control M1 FOBS FOR PROX READER Would I need "ELK M1PR M1 MINI PROX READER FOR KEYPAD" in order to use the ELK-6010 and M1 FOBS with the keypad? I noticed that the M1KP2 keypad has a possibility to have an external RF reader connected, but does it also have an internal RF reader? Two ELK-71 or ELK-74 sirens. How can i connect both of them to the M1 board?
Few more questions, what is the main purpose of the internal speaker that comes with the kit. Should it be installed in the interior of the house, or I can keep it in the attic? Also, the sirens. where is the best place to mount them?
How long should I expect the batteries on the door sensors to last?
