Just FYI, with PLM's none existent, the fear is one of my three I have in service will die ... and the call came today from my kid ... ISY is dead
Did normal reset etc ... PLM status showed NOT connected.
Brought it to my house and tried several more resets, same status, ISY showed no PLM connected. Cracked the case and checked the capacitors, they all look good.
A few years back I had my own failure, and read somewhere to reset the PLM x 3 in a row ... holding the reset a little longer after the buzzer stopped ... so I did and with luck this PLM works again
Not sure if its on its last legs, but hopefully it lasts until PLM's are back in stock
Just thought I would post this for anyone else who might have a "questionable" PLM ... its worth the extra few minutes to try
