5.8.1 Description
The DPH(4)-U13 ETU provides connection for four
Doorphones (DP-D-1D), and also provides the associated
four Door Lock Release relays.
Doorphones and relays are paired together so that a
station user talking into a doorphone, controls only that
Door Lock Release relay when the feature code is dialled.
The DPH(4)-U13 has two audio paths to be shared by four
doorphones. Two simultaneous doorphone calls are
allowed. Doorphones 1/3 and 2/4 are paired together.
