Valcom 12" & 16" Wireless Clock Installation Manual
IMPORTANT: We highly recommend installing the main transceiver (V-WMCA) before the
installation of the Valcom Wireless analog clocks.
In order to install the clock, simply remove the battery cover, and install two (2) D cell batteries
(recommended battery type: Duracell
battery cover and the clock should start correcting within five (5) minutes.
The Valcom Wireless Analog Series clocks have two (2) different modes in which they will operate.
Normal mode allows the clock to transmit/receive every two (2) hours. This mode will allow the
clock to have a 5 year battery life (provided good reception). Economical mode allows the clock to
transmit/receive every four (4) hours. This mode will allow the clock to have a 8 year battery life
(provided good reception).
Normal mode is defaulted when shipped from the factory.
To toggle this mode, push and release the Diagnostic Switch and the Transmit/Receive switch si-
multaneously. If 5 year mode is selected, the LED will be solid RED for one minute and the second
hand will go to 5 (25 seconds). If 8 year mode is selected, the LED will be solid GREEN for one
minute and the second hand will go to 8 (40 seconds).
IMPORTANT: If a clock is being added to an existing system (existing clocks date coded
prior to December 2009), it must be in normal mode.
There are four (4) ways to install Valcom's Analog Wireless Clock system. The user can choose
any of the combinations listed below, or any combination of the three (3).
Option #1:
There is a main high powered transceiver in the building (V-WMCA) and repeaters (V-
WMCRA) as needed to cover the entire premise. In this option, the system does not depend
on the slave clocks for transmission.
Option #2:
There is at least one (1) high powered transceiver (V-WMCA) in the building and in order to
cover the entire premise, the battery-operated clocks are used as transceivers/repeaters.
Option #3:
There is at least one (1) high powered transceiver (V-WMCA) in the building and in order to
cover the entire premise, the power (24V or 110V) operated clocks are used as transceiv-
ers/repeaters.
Option #4:
There are multiple transmitters that will cover the entire building or campus.
