G. Door Strike Activation Time
A single pole double throw relay is available for each entry phone (a second set of contacts are
available on solder pads only), and each may be programmed with its own “doorstrike” activation time
(programmed in seconds). Each time must be 2 digits (Example: 00 = 1/2 sec.) and is stored in
locations
#19
,
#29
,
#39
and
#49
for relays 1 through 4 respectively. All activation times are factory set
to 00 (1/2 sec.)
Note: A buzz sound will be heard in the house phone and entry phone, indicating the door strike relay
has been activated and visitors can now open the door.
H. Caller ID
The
DCH4
is factory set to send “Caller ID” and “Call Waiting Caller ID” information from the entry
phones. If “Caller ID” is not required, enter “*
2
” while in programming to disable the
DCH4
from
sending “Caller ID” and “Call Waiting Caller ID” data to the house phones. Enter “*
1
” to enable “Caller
ID” and “Call Waiting Caller ID” data (see
Operation
section
A
).
I. Entry Phone Ring Cadence
Entry phone calls are factory set to ring the house phones in a custom double ring cadence (.7
seconds on/.3 seconds off/.7 seconds on then 4 seconds off between rings), “*
3
”. The
DCH4
can be
programmed to give a standard ring cadence for entry phone calls (2 seconds of ring, and 4 seconds
off between rings), enter “*
4
” when in programming. Entry phone ringing can also be disabled
by entering “
0#62
”. This is useful when connecting the
DCH4
to the
DPC100
to provide unique front
and back door chimes.
J. Outside Line Access
1. Dial “9” to Access the Outside Line -
To program the
DCH4
for C.O. dial tone, enter “*
5
” while
programming. To gain access to C.O. dial tone, dial a Touch Tone “
9
”.
2. Instant Outside Line Access (factory default) -
To program the
DCH4
for private dial tone, enter
“*
6
” while programming. House phones will instantly have the outside line dial tone on an off-hook.
K. Maximum Entry Phone Ring Count
The number of times an entry phone call will ring the house phones can be limited in programming.
The programmable maximum ring count must be 2 digits and is stored in location “
#61
”. The
maximum ring count is programmable from 1 - 99 and factory set to (
05
) 5 rings.
L. Doorbell Switch Input and Auxiliary Contact Output
1. Doorbell Mode
(DIP Switch 1 ON - factory setting)
With the
DCH4
in the doorbell mode (DIP switch
1 ON
), a normally open switch (SPST 6-16V lighted
or non-lighted doorbell button, etc.) can be connected to terminals 26 and 27 (
DOORBELL SWITCH /
AUX INPUT
). This switch should be located near entry phone 1. Door chime power (normally
connected to a doorbell button) can be routed through terminals 28 and 29 (
N.O. AUX CONTACT
OUTPUT
). A momentary closure on the
DCH4
input terminals will momentarily activate the
AUX
CONTACT OUTPUT
terminals for the same duration, activating your door chime. Entry phone 1 will
be called, automatically answer (see the Technical Practice for your entry phone) and begin ringing
the house phones (terminals 4 and 5
LINE OUT TO PHONES
). The house phones can then be
answered, doorstrike commands entered, etc. (see
Operation
sections
A-E
).
Notes: Entry phone 1 ringing the house phones can be disabled in this doorbell mode, if it is
desirable to have the doorbell chime but not the house phones ring. This option can only be used if
