Need More Information on W-3000?
Call (715) 386-4345 and select 180.
B. Speaker Volume
The SPKR VOL pot can be adjusted to increase or decrease the speaker volume
to the level desired as shown above.
In certain noisy locations (background traffic, machinery or wind), the microphone volume may need to be decreased.
A symptom of this is one-way talk path, in which the distant party cannot be heard over the speaker. A “MIC VOL”
adjustment is provided on the W-1000/2000A for increasing or decreasing the microphone volume. Notes: If the micro-
phone volume is set too high or too low, one-way talk path may occur. For extremely noisy environments, use the W-
3000 in the “PUSH to TALK” mode.

In the idle state, the W-1000 or W-2000A provides 24V DC talk battery. When the “Call” button is pressed, the W-1000 or
W-2000A generates a standard ring cadence (approximately 1 second ON and 3 seconds OFF) that is adjustable to 2, 3,
10 or 30 rings. When the call is answered, ringing will stop automatically and the calling party can converse handsfree (sim-
ilar to a speakerphone) with the called party. The talk path will be maintained until the called party (inside phone) hangs up.
C-1000A Door Entry Controller
The C-1000A Controller dramatically expands the potential installation sites for many peripherals
such as doorboxes and paging amplifiers. Doorboxes and paging amplifiers can now be used on sin-
gle line, residential or home office applications as well as on fully loaded systems, because they are
no longer limited to installation on unused trunk ports. The C-1000A allows single line phones or
phone systems to share a phone line with one or two doorboxes or paging amplifiers. In addition, the
C-1000A provides two Touch Tone controlled relays to
operate door strikes or gate openers.

RC-2A Remote Touch Tone Controller
The RC-2A Remote Controller provides remote relay operation from any standard Touch Tone tele-
phone.
The controller is designed to be installed either locally or remotely. For local installations the RC-
2A can be installed in series on any analog communications path, such as analog C.O. lines, ana-
log PABX/KSU stations or Viking’s W-Series Doorboxes. and will passively monitor for Touch
Tone commands. For off-premise applications, the RC-2A will answer analog C.O. lines or
PABX/KSU stations after a selectable ring delay. A field programmable access code can also be
programmed to prevent unauthorized usage. The
RC-2A will then allow remote relay operation.
LDB-3 Advanced Ring/Loop Detector
The LDB-3 Advanced Loop Detector monitors an analog phone line for ringing and/or an off hook condition. A built-
in relay can be activated when either of these conditions are detected. This is ideal for monitoring line status or
for providing a visual indication of such.
The LDB-3 can be used with any W-Series doorbox to provide a dry contact closure when the button is pressed
on the doorbox and can be maintained while communicating with the doorbox if desired. This contact closure can
be used to trigger a security camera or activate a doorbell system. The LDB-3 comes complete with a 12 VDC
power adapter, and can also provide switched 12VDC .35 Amp output
to power external lights, etc. during ringing and/or off-hook conditions.
