i've purchased a Honewell 8EP416-EU to replace the RCP on my C&K Securit 800L. Please would you confirm which connections (COMMS and SOUND) correspond to C and D on the old Securit RCP?
Thank you.

You can't, an accenta keypad is for an accenta and optima

 

That’s no problem and I’m happy to also replace the control box as required.

I have looked at the installation manual for the Accenta and some of the screw comnection are labelled differently to my existing 800L unit.

Please would you advise which connnections on the Accenta control unit, correspond to the following (existing) connections on my 800L:

-R

S

ST

Many thanks,
 

They are the bell tamper and trigger connections

from memory (as the 800l is long obsolete)

-r is tamper return

S is bell trigger

ST is strobe
