1WWVB1000 - WWVB Radio Time Code Receiver - User Manual - Version 1.1
1 - Introduction
The WWVB1000 is an economical radio time code receiver system
designed to synchronise to the WWVB radio transmission broadcast
from Fort Collins, Colorado. Once synchronised, the receiver provides
time and date information to an MC Series master clock via a cable
connection.
The wide sensitivity range of the WWVB1000 allows reliable signal
decoding towards the limits of the broadcast range. Please refer to
section 2 for installation recommendations and section 3 for details of
conrming system operation.
1.1 - Package contents
The WWVB1000 is supplied with the following component parts:
• WWVB1000 60 kHz WWVB Radio Time Code Receiver
• Cable for connection to a World Time Solutions MC Series master
clock (Please note: The length of cable supplied is dependent on
the model ordered. See appendix A for details)
• 5 way socket block connector for connection to an MC Series
master clock
• A4 user manual

2 - Installing the WWVB1000
The WWVB1000 should be installed in a suitable location following
the recommendations in section 2.1 below. The system should be
xed in place and then connected to the MC Series master clock
using the supplied cable. If required, the cable may be extended by
following the recommendations in section 2.3.
2.1 - Recommended installation locations
To achieve the most reliable operation the WWVB1000 should be
installed in the following optimum location:
• On the outside of a building, away from any metallic objects or
electrically noisy equipment. The antenna should be positioned
on the side of the building closest to the transmitter. In addition,
the front (clear) face of the antenna should be facing towards the
transmitter. (The transmitter is located in Fort Collins, Colorado).
If external installation is not practical, depending on the signal strength
and the level of radio interference, it may be acceptable to install the
antenna in the following location:
• Mounted internally, away from any metallic objects or electrically
noisy equipment. The front (clear) face of the antenna should be
facing towards the transmitter. (The transmitter is located in Fort
Collins, Colorado).
WARNING: THE WWVB1000 SHOULD NOT BE INSTALLED IN
ALOCATIONSUSCEPTIBLETOADIRECTLIGHTNINGSTRIKE.
2.2 - Physical installation
IT IS RECOMMENDED THAT THE ANTENNA SHOULD NOT
BE PERMANENTLY FIXED IN POSITION BEFORE SIGNAL
RECEPTIONHASBEENCONFIRMED.
The WWVB1000 should be secured in position using the four 4.5mm
(0.178”) case xing points (see the drawing in section 1.2). Care
should be taken to ensure the xings used (not supplied) are suitable
for the application.
2.3 - Connecting to the master clock
The WWVB1000 is supplied with a length of four core cable for
connection to an MC Series master clock. The cable should connect
the WWVB1000 cable xing point to a Remote Synchronisation Input
on the master clock. Please refer to the drawing on the following
page and table 2.1 for details of cable connections.

If required, the cable may be extended using Belden 9502 type cable
up to a maximum total length of 150m (500ft). For low smoke/plenum
applications, the supplied cable should be substituted for a Belden
82502 (or equivalent) type cable.

3 - System operation
Following installation (see section 2) and upon powering the MC
Series master clock, the WWVB1000 will automatically attempt to
synchronise to the WWVB radio signal. The WWVB1000 also begins
to send setup information to the master clock.
Depending on signal strength and the level of radio interference,
system lock may take up to 30 minutes. Once the WWVB1000
has synchronised to the WWVB radio transmission, time and date
information is automatically sent to the master clock.
3.1 - WWVB1000 status information
The operational status of the WWVB1000 may be visually conrmed
via the status LEDs (see gure 1.1). The table below lists the function
of the different LEDs.
LED Status
Power
Green LED illuminates continuously when power is applied
to the WWVB1000 and the system is running
Lock
Green LED illuminates continuously when the WWVB1000 is
synchronised to the WWVB transmission
Data
Green LED ashes to indicate WWVB data being received
Fault
Red LED illuminates if no radio data is detected for a
prolonged period
Table 3.1 - Status LEDs
The synchronisation status may also be conrmed via the MC Series
master clock. Please refer to the user manual supplied with the
master clock for further details.
3.2 - Improving signal reception
The radio detection circuit in the WWVB1000 radio time code receiver
is highly directional in its ability to decode the WWVB signals. To
enable the best reception of the WWVB signal, the installer should
ensure that the decoder circuit is properly aligned with the WWVB
transmitter (located in Fort Collins, Colorado).
Alignment may be conrmed by slowly rotating the WWVB1000 and
observing the operation of the ‘Data’ LED. When correctly aligned,
the ‘Data’ LED should ash once per second.
