Motorola GR500 on battery power


Flameout

Question

I'm a little hesitant to ask another question, as some seem to be bothered by them, but here goes.

I have a wall mount GR500 repeater that works quite well and I was testing out the battery backup, which also works well. I was just wondering how to activate the "beep" to warn that the repeater is running on backup power. I can't find it anywhere in the software. This is from the repeaterbuilder page concerning this repeater

The battery revert kit board generates an "On Battery" output signal (active low) that can be connected to the R1225 accessory connector, and optionally in parallel to an external repeater controller. If enabled in the R1225 RSS / CPS programming the "On Battery" signal causes a "beep" signal to be generated on the transmitter when you are running from the battery.

Does it have the battery revert board in it ? Most did not ship with it. The standard power supply in the GR500 does not have the output needed to give the Active low to the repeater. If you have the proper battery revert PS below has the info on soldering to the board to get the 3 wires you will need. Page 7 of the manual below.

Oh, now I'm not sure. I just assumed it did since there was 13.6v at the battery connection on the rear and when I removed the 110v to the power supply, it kicked over and ran on battery power

Ya most of them did not come with this PS. The standard one in the GR500 case is to be honest the better one. 

This is what the revert kit looks like. It would of been added after and you would not use the screw terminals on the outside for it.

Also it will take forever to charge a dead battery. If you do run on battery for any length of time I would pull the battery and put it on a good charger to verify. Short power outages are fine but if it goes until the battery is dead and repeater shuts down use a good charger. Also always fuse the battery cable as close to the battery as you can.
