Re: LD11 - Can it be altered to operate using 12v dc or 24v dc

["Frank Mc Alinden" <fmcalind@xxxxxxxxxxxxxx>]

Hi John
I believe the ld11 button connections are at mains voltage
...240v........

What you could do is use the cat5 cable to operate small industrial type
12v
dc relays back at Node 0 and connect the contacts of the relays across the
ld11 button connections....????
