Seems that lately I have been doing nothing but installing doorphones for customers. I had a huge inventory of doorphones and relays that I depleted within just the last week alone.
|Two SPA112 devices.|
One is for 2 separate door phones
One is for 2 analog lines added to the door phone ring group.
One RC2A - only one of the doors that got a doorphone installed has a doorlatch,
the other door is always open during business hours and did not require a relay.
|Since the analog stations were placed within the warehouse so that workers|
would be made aware when someone was ringing the door phone
a loud ringer had to be added above those phones so that people could hear
from anywhere in the warehouse that someone was at the door.
The customer picked these up on their own, and I am extremely impressed
with this model. All that is required is a connection to the phone line
it is powered by the ringing voltage of the phone line it is connected to.
