Trouble code 7 on PK5501

I have a PK5501 keypad on a PC1616 control panel. I am get the orange triangle and the beeping. After pressing *2, it shows trouble code 7, low wireless device battery, but I have no wireless devices on the system that I know of. I have powered down the system twice by unplugging the power and battery and the trouble 7 comes back after a couple of days and it always seems to start beeping at 3 in the morning. Can anyone assist me it finding out what the issue is?

Are you _sure_ you don't have wireless devices? Does it display a zone number if your press 7 after pressing *2?

How many zones are on your system? If there are more than 6, then you almost certainly have wireless devices.

I'm pretty sure there is no wireless devices, all of the sensors on the windows and doors have wires going to them. If I press 7 after I press *2, a big 7 shows on the display. On the cover of the key pad it is labeled
1. Front/ Side door
2.motion
3. Back door/ Front door
4. Side windows
5. 1-6 Back windows
6. 7-11 Front/ Bed Windows

How many zones would that be?

That's 6 zones. Press 7 after pressing *2, that will display the zone number of the device with the low battery.

You may have wireless keyfobs, or possibly wireless smoke detectors.

See the table on page 60-62 of the installer manual: http://cms.dsc.com/download.php?t=1&id=17007

After I press *2 a small 7 appears at the top, then I press 7 again and a larger 7 appears a little lower. I know I do not have any wireless key fobs. I looked at the smoke alarm, it has wires going to it. It is a Napco FW-2 smoke alarm, I looked at the manual for it and it has no battery.

Based on that, somewhere in your system there may be a forgotten wireless device on zone 7. Is your keypad a PK5501-RF model? If so, then the keypad is the wireless receiver.

There are several models of wireless transmitter that are very small, and could be easily in a door/window frame, and thus not visible.

Sometimes installers work around damaged inaccessible wiring by just adding a wireless device or two to the system. It just sounds like you were given an incomplete zone list.

"6. 7-11 Front/ Bed Windows " This makes me wonder if they might have used wireless devices on those windows, since the way they wrote the label is a little odd.

One key pad is a PK5501 and one is a RFK5501-433. I looked in both of them and did not see any batteries. Both have wires going to them, if the RFK5501 has a battery,where would it be?

I found it, it was the sensor on the back door. It is wireless, I was wrong. Thank you for the help.
