Yale EF touch screen alarm panel and power supply - I have reset the panel and it’s ready to use on a new system (see the photo attached). The panel backup battery likely will require replacement as gives a red triangle warning when the battery is turned on after a while (when mains power turned off) - but this does not stop the panel working as designed. You can set up without the battery turned on and this seems to stop the red warning triangle. Panel is in good cosmetic condition and has been well looked after. I will also enclose instructions for set up.
