L. Doorbell Switch Input and Auxiliary Contact Output
1. Doorbell Mode (DIP Switch 1 ON - factory setting)
With the C-2000A 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 C-2000A DOORBELL SWITCH input terminals will momentarily acti-
vate 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 sec-
tions A-E).
Notes:
2. Auxiliary Contact Mode (DIP Switch 1 OFF)
With the C-2000A in the auxiliary contact mode (DIP switch 1 OFF), the auxiliary contact output can be programmed (see
Programming section B) to activate in 3 different patterns when entry phones 1-4 are off-hook. These patterns include a
momentary activation, a continuous activation while the entry phone is in use, and a ring cadence pattern. A fourth programmed
setting is also available for a timed activation of the auxiliary relay from a contact closure.
a. Entry Phone Triggered Timed Activation (0.5 second factory default with DIP switch 1 OFF)
With the entry phone triggered timed activation programmed (1 followed by #60), when any entry phone is activated, the aux-
iliary contacts will activate for the programmed time (0.5 - 99 seconds) in memory location #59 (see section M below).
b. Entry Phone Triggered Continuous Activation
With the entry phone triggered continuous activation programmed (2 followed by #60), when any entry phone is activated,
the auxiliary contacts will activate continuously (latch) until the entry phone disconnects. This is ideal for controlling video
cameras, lights, etc. In this mode only, when a house phone has dialed a monitor command (#1, #2, #3 or #4) to connect to
an entry phone, the C-2000A will latch the auxiliary relay during the "monitor" once the entry phone answers (so a camera
or light can be activated while monitoring.
c. Entry Phone Triggered Ring Cadence Activation
With the entry phone triggered ring cadence activation programmed (3 followed by #60), when entry phone 1 is activated, a
repeating 1 second on and 3 seconds off auxiliary contact pattern is generated. When entry phone 2, 3, or 4 is activated, a
repeating double burst contact pattern is generated with 3 seconds off between patterns. The auxiliary contact pattern stops
when the house phone answers the call from the entry phone. This is ideal for controlling visual ring indicators, or connect-
ing to a model SLP-1 for unique front and back door chimes.
d. Auxiliary Input Triggered Timed Activation
With the auxiliary input triggered timed activation programmed (4 followed by #60), a momentary contact closure on the
DOORBELL/AUX INPUT will activate the auxiliary contacts for the programmed time (0.5 - 99 seconds in memory location
#59, see section M below). The auxiliary contacts may be used to provide an additional relay or may be used to add
doorstrike entry to an entry phone that does not have a Touch Tone keypad. The auxiliary input contacts may also be used
for timed operation of other devices such as yard lights, etc. and can be triggered by the second set of door entry contacts
(available through solder pads on the C-2000A PCB).
M. Auxiliary Contact Timing
To program the length of time the "AUXILIARY CONTACT" is activated when triggered from an entry phone or the "AUX
INPUT", enter 00 - 99 followed by #59.

A. Visitors
When a visitor presses the call button (comes off-hook) on the entry phone, the C-2000A will
begin ringing the house phones and "Caller ID" information is sent. If a house phone is on a
C.O. call, call waiting tones and "Call Waiting Caller ID" information is sent. A Touch Tone "#"
from the house phone will put the C.O. call on hold and connect the house phone to the entry
phone (beeps will be heard, indicating which entry phone you are connected to). Enter Touch
Tones ",," to momentarily activate that entry phone doorstrike and return to the C.O. call or
enter "#" to just return to the C.O. call without activating the doorstrike. If the doorstrike is acti-
vated, a buzz sound will be heard confirming the strike has been activated.
If you require the door strike to remain on continuously (ie: a truck delivery), enter Touch
Tones ",1" to continuously activate that relay and return to the C.O. call. A 5 second buzz
sound will indicate the door strike relay is latched on. When the visitor calls in again (ie: they are finished unloading the truck), enter
Touch Tones ",0" to deactivate the relay. Alternatively, the doorstrike relay can be de-activated by going off-hook with any house
phone and entering #1,0 for doorstrike relay 1, #2,0 for doorstrike relay 2, etc. See Operation section C. A short buzz will indi-
cate the door strike relay is off.
