M1XEP and Power

I have read a couple of messages here that say it's possible to wire the M1XEP to the M1G for power. I have the M1XEP and M1G in the same can and would love to provide the power from the panel. I like the idea of having the battery there to provide backup. I'm not against putting a battery backup in the can but haven't found one small enough to fit and I'm not against buying a bigger battery or a second battery as some have suggested. Another option I have thought about but not looked further at is getting one of the poe injectors/splitters to possibly power the XEP.

Currently I have the following:
M1G
M1XEP
2 - Serial Expanders
M1XOVR
3 - Keypads
2 Temp Sensors
3 Smoke
5 Window Sensors
4 Motions
7 Doors
2 Glass Breaks
Two Way Listen In TWA
4 Flush Mount Speaker/Mics

Can you help me with what the best option to get the XEP powered so that it has a few minutes of runtime at least when the power goes out? The best option probably would be a poe injector/splitter for me as where the ethernet terminates is on battery backup/generator.

Thanks,

Andy

and a data bus hub.
 
There are plenty of threads on this. Basically it comes down to how much time you want on your battery and making sure you don't go over the M1's power limits. I think typically most people opt to power the XEP separately, as it is a big chunk of the M1's power quota. Also, you need to consider the usefulness of having it backed up. To utilize it you would also need power for any switches, routers and modems and I doubt you will be able to power all of that via the M1.

I added an additional 14" can, power supply and battery to power all of my network equipment and XEP.

So are you using a PD9 or how do you have the power supply/battery hooked up? Sorry am new to this. I read the other threads on this but have not found one that really explains how to do it.

I have an additional Elk 12v power supply and battery. My router, modem and XEP are just wired to it's terminals. The hardest part was trying to come up with the right sized barrel connectors for my devices, I ended up taking the original power supplies and clipping the connectors off and using those.

A PD9 is just a way to break out terminals with a power switch, some LEDs and maybe individual terminal protection. It's not really needed, over terminal strips. I do have a couple but those hooked to my M1 to break out power for my motion detectors, etc. But they are overkill and not really needed. If I had to do that over again I would save some space and $$$ and just use terminal strips.

I have my M1XEP, Router and Cable modem all powered by a UPS. Not as clean as what Wuench has done but it works and was easy.

Edit: Spelling
 
I power my M1XEP (and a few other things) with a Tripp-Lite AV550SC UPS. It's built to fit inside a can. It has several A/C outlets and 12Vdc (up to one amp). It has suppression jacks for phone/DSL and cable/satellite coax. I've had it for about six months and no problems yet. The only thing I'm not sure about is the battery. It doesn't say what battery it uses, and says the battery should only be replaced by an authorized repair shop, and I haven't been able to find out what battery it uses. Opening the case voids the warranty, so I can't get the battery number that way.

+2 on Wuech set up.....done pretty much the same. Keep it seperately powered up as you will keep adding to you system and always good engieering practice to have some power supply headroom. Don't forget that when the M1 goes into alarm extra power is drawn driving flashing lights a sirens.

thanks for all the feedback. I'm definitely going to keep it separate but am leaning towards remotely powering it with a power over ethernet module as that has added advantages for me. Where all my computer equipment is has battery backup and generator on it. If the poe adapter doesn't work then I will either order the ups mentioned here or will see if I can find another one that will fit in the can.

Thanks again for all the feedback.

That is one good point, with all of these solutions (unless you get a smart UPS) you will have no indication of when your second battery (or UPS) needs to be replaced. The M1 does run tests on the primary battery. Unless you are going to routinely test it, you may find in a power outage that it doesn't work.

I am now thinking for my setup, it might not be a bad idea to do a routine battery swap between the external power supply an the M1 (since both batteries are the same) and let the M1 tell me when one goes bad.
 
To power the M1XEP from the M1:
1. Cut the power cord off the wall wart power supply.
2. Attach the power cord to the Aux power terminals on the M1. Positive should go to the wire that connects to the center of the barrel connector. You can use a volt meter to verify you have the power connected properly. Negative on the outside of the barrel and positive on the inside of the barrel connector.
3. Make sure you are not overloading the M1's power supply.

Personally I like this because it gets rid of power line transients and interruptions that can cause the XEP to reset.
 
If the XEP is powered externally & AC power fails & the external power (UPS/battery/whatever) fails before the main M1 battery, will the loss of communication with the XEP trigger a trouble condition?
