How to find which wireless RF switch has a low battery

Hi all, I have quite a few RF wireless sensors/switches. The Elk event log shows "Low battery on RF sensor" but doesn't tell me which one. Any way to work out which one it may be?
 
Thanks

Don't have any wireless on my system so I can't say if this will work for sure.
 
If you have something to monitor and decode the packets broadcast from the XEP (or serial port), you should be able to get the zone number from the "SS" (system trouble status) packet.  According to the ASCII protocol manual, the zone number for a transmitter low battery is encoded in the packet.   See page 44 or thereabouts.

I think that the Elk transmitter sends the low battery message to the control when it is switched. I would try violating them one at a time while watching the log.

The 6030 holds 2 x CR123A Lithium batteries. The
estimated service life is 5 to 7 years in a typical residential
installation with the Sleep Cycle set to LG (Long),
Battery #1 (lower) is supervised for low voltage.
 
When
the sensor detects the voltage has reached 2.6 VDC or
less (under load), a Sensor Low Battery trouble will be
transmitted to the control/transceiver. This trouble will
be attached to all future transmissions until fresh new
batteries are installed. Battery #1 is the primary power
source for all critical functions (motion detect and radio
transmission) of the 6030 sensor.
Battery #2 (upper) is not-supervised for low voltage.
This battery is a secondary (reserve) power source for
the 6030 critical functions, but it is the primary (sole)
power source for the White Security/Convenience LED.
The White Security/Convenience LED will not operate
without a good battery installed in Battery #2 location.
We strongly recommend installing a battery in both
locations. These 2 batteries are electrically isolated in
such a way that critical functions of the 6030 can draw
power from either battery, but the White Convenience
LED can only draw power from Battery #2.

Thanks all for the replies, I've used the desktop Elk software to view the panel log. It also included the "extended data" which shows the sensor that had an issue
 
My sensors are Australian versions, so not 6030 you referred to. They only contain a single battery.
 
Cheers

Sorry but I was confused. I shouldn't have assumed that you have the elk brand sensors and the 6030 that I referred to is the elk wireless motion sensor. I do dumb things when I rush.
