4140, system was taken over & placed on redcare
they got a new building & the alrm was taken over & extended with a TS Networker, one of the 1st systems I had on UDL,
no, it took me ages to find out what co. made them, but they either no longer exist or no do anything "alarms"
They where mild steel lid & back plate,
a coated PCB with plastic cone speaker under it
err the book say 4140/ 4170
if you also have an accord book in the binder it might but prudent to post a pic of that,
I once had a 4140 on redcare.... not touched it 15yrs ?
Drove by on tuesday, my sticker are still on the EWD's
err... the only ungraded stuff I see is removing optima's
Pyronix, panel's paragon, conquer, & sterlings where proper dogshit,
