Good Afternoon,

Could anyone please advise how many door phones can work on a BCM50 release 2.0 or above??

Thanks in advance.
 
I'm Just guessing but as many as you have Analog ports or ATA's on Digital ports. A door phone is just an Analog phone.




This is a Signature and not part of the answer, it appears on every reply.

This is an Analogy so don't take it personally as some have.

Why change the engine if all you need is to change the spark plugs.


 
I don't know for sure either but BCM or Norstar door phones are digital.
 
I stand corrected.

This is from the Doorphone installation guide:

Note: A maximum of 250 BST Doorphones can be attached to the BCM system.

That doesn't make any sense to me as the limitation exceeds the capacity of even a maxed-out BCM400, so I'd say on a 50, the max would be 44.
