The Low Battery symbol has appeared in the lower right corner of the e7w display in a room, but
no "Device with Low Battery" indication has appeared for the room in IC3/IC5 Room View or no
Low Battery alarm occurred in IC3 or IC5 .
Possible Reasons:
The room the e7w is installed in is not correctly setup to communicate with the Inncom server. There
must be a device in the room configured as the room gateway that is communicating through an Edge
Router or B576 Floor Bridge to the Inncom server. The e7w must be set to the same Room ID, PAN ID
and RF Channel as that room gateway. Verify the Room ID, PAN ID and RF Channel set into the e7w
are correct for the particular room and perform a WAN test (see Appendix 7) from the e7w service
parameter mode to verify the Room Gateway for the room is online with the server. Verify you can
Ping the room gateway device address using the e7w Pn6 (Ping) parameter (see Appendix 8).
It can take time before the low battery condition of the e7w gets reported to the server.
The e7w only reports its battery state after the e7w connects to its Smart Wall Plate following battery
insertion and every 18 hours. It sends a "Device Information" message that includes its battery state
that is routed through the Room Gateway to the Inncom server. This message reports the e7w
battery status as normal (> 4VDC) or low (< 4VDC).
Therefore , if the voltage of the 4 AA batteries drop below 4VDC during normal operation, the next
every 18 hour Device Information message sent by the e7w will report a low battery condition, and
the Low Battery indication for the room in IC3 /IC5 will be set and a low battery alarm will occur.

I replaced the batteries in the e7w, but there is still a low battery indication for the room in IC3/IC5

Possible Reason:
➢ The e7w was not correctly connected back to the SWP (Smart Wall Plate) after replacing the batteries.
Verify the e7w is fully connected to its SWP. The e7w would be displaying "SWP" if it was not fully
connected to the SWP.
1. Un-screw the 2 captive screws at the bottom of the e7w that attach the e7w to the SWP and re-fit
the e7w to the SWP.
2. Make sure 2 tabs at the top of the e7w are fully inserted into the 2 slots at the top of the SWP, then
rotate the bottom of the e7w and push onto the SWP so the 2 tabs at the bottom of the SWP snap
into the slots at the bottom of the e7w.
3. Screw in the 2 captive screws to permanently mount the e7w.
4. Wait 10 seconds and see if the SWP indication clears and is replaced by a temperature value. This
indicates the e7w connected to the SWP. The low battery indication should clear for the room in
IC3/IC5 within 1-2 minutes.
If the low battery indication in IC3/IC5 does not clear, it is possible the message sent from the e7w
to the server reporting its battery state after inserting the new batteries and connecting the e7w
to the SWP did not reach the Inncom server. It is only one sent one time after connecting the e7w
to the SWP following battery replacement, and then is sent every 18 hours.
