List of items I need for Elk M1G wireless operation and Uplink 2500 add-on connection?

[BulletHead]

I have the following for my Elk M1G with hardwired smokes and COs. At the time I was in the middle of gutting/re-framing the house, I totally overlooked hard wiring for the window sensors or for glass break sensors. So now I want to add a few GE NX-488 glass break sensors and also an Uplink 2500 for primary communication (I have IP monitoring currently via AlarmRelay (no POTS)), is this what I would need?

I may add other wireless devices like camera, etc.

Currently Installed Elk M1G:
M1Gsys4s with M1KP2
1280 8Ah battery
M1XEP ethernet module
GE-ESL541NCSXTE smoke detectors (built-in relay, sounder) (qty 6)
GE-ESL250-CO CO detectors (qty 3)
GE-ESL405-03 polarity reversing module
VIS-VI-PET pet tolerant motion (qty 2)
GRI-GRIRB01T-W roller ball for entry door (qty 1)

Add-ons desired/needed:
M1XRFEG wireless receiver
GE NX488 glass break sensors (qty 5)

P983 power supply with can
M1DBH Data bus hub
W018B RS485 cable (from DBH to M1G panel)
Uplink 2500
M1XSP serial port expander
W046A serial cable (M1XSP to Uplink 2500)
1208J2 battery
TRG1640 transformer


Am I missing something?

Im thinking I may have to go with a 1280 battery because of the current draw.

edit: scratch that, i already have a 1280, i think with that additional 1208 for the Uplink 2500 and its power supply, i should be ok for a 4 hr standby.

The Uplink will take very very very little current while idle. It will pull up to 2A if communicating but my understanding is thats for a very very short time (milliseconds). One 1280 battery should be plenty for that.

If you are running smokes off your main panel, Id consider 2 1280s for that since you technically need 24 hours of backup if smokes are attached.

Yes, I am running the smokes and CO off the panel. Ok, I will go with 2 - 1280s. Thx.
