What's the difference in these XEP setups

[jmed999]

Currently my XEP is plugged into an outlet using the transformer that came with the XEP. In this setup the XEP goes dead during a power outage. I want to allow the XEP to be on backup power and still send signals during a power outage. I have IP monitoring and cell (Uplink 2500) as a backup. My router and modem are on UPS. So I decided to do this...

1) I bought a P212S to use with the currently being used XEP. I also bought a transformer, low battery cutoff, and will buy a battery and surge protector. This will allow the XEP to run even during a power loss.

2) I'm now wondering if I should just meter out the barrel connector and power the XEP via the power outputs from the Elk control panel itself. I could return the P212S, transformer, and low battery cutoff. I also wouldn't need an additional battery and surge protector for the XEP.

Besides #2 being cheaper what is the difference in #1 and #2? Is #1 better? If so how?


Thanks for your help!!!


PS. I currently have the NAV keypad, wireless receiver (Elk-M1XRFEG) and 20 Watt speaker (Elk-73) connected to the M1 control panel. I will be adding smoke and carbon monoxide detectors soon. Not sure if those are powered from the M1 control panel or not. I will likely also add another speaker for the attic.

You need to do the voltage calcs and determine if you have enough headroom on your panel (1A) to support your hardware and the XEP powered from either that or a separate supply.

I've run XEP's multiple times on the panel or aux supplies since it usually frees up an outlet and tames the clutter.

The smartest way is to run one leg of the power through a relay (or OUT3 if unused) on the board to allow a "self-healing" or reboot automatically via appropriate rules.
