Viking's Wireless Clock System provides reliable, accurately synchronized clocks for your entire facility. Eliminating dedicated clock wiring can save you thousands of dollars on installation
and also allows for easy retrofitting of an existing installation. While most wireless systems are limited to the range of the transmitter, Viking's system is not. Each clock acts as a Repeater
(transceiver), meaning the secondary clocks both receive and retransmit the signal, maximizing signal transmission distances. The system is comprised of a CTG-2A master clock, a CL-
RFT clock RF transmitter and Analog or Digital wireless slave clocks. Working on Viking's 915-928MHz frequency hopping technology eliminates interference with other wireless products
and requires no FCC license, eliminating extraneous fees. The received signal remains strong even under the effects of noise, obstructions or long distances which tend to decrease the
signal to noise ratio. Installation is a cinch for our wireless clocks, just insert the batteries or connect power and hang them. That's it.
Viking's CL Series wireless clocks include automatic calibration, as well as diagnostics
that allow the user to view the signal strength, how long since the last time the clock
received a signal, a comprehensive analysis of the clock itself and remaining battery
life. The 12 and 16 inch wireless Analog clocks receive and retransmit an RF clock
sync signal every 4 hours (standard mode) or 12 hours (economy mode) allowing for
a battery life of 5 years or 8 years respectively. The 2.5 and 4 inch digital clocks are
powered by an included power adapter and receive and retransmit an RF clock sync
signal every minute. Viking also offers a complete line of accessories for the Analog or
Digital clocks such as: double mount housings, wire guards and surface mount housings
(for digital clocks only).

  • Page 3 C. Wiring and Jumper Settings (Transmitter / Repeater Configuration) The wireless Transmitter / Repeater can be configured to use either incoming wireless signals or RS485 data from the CTG-2A as a means of recieving time. To change the time data source:...
  • Page 4 (analog wireless clock only), or 24 volts (digital clocks only). Will the Transmitter/Repeater have interference from cordless or cellular phones? No, because with Viking’s innovative frequency-hopping technology, interference will not occur. The repeater switches frequencies automatically when the receiver and transmitter is open, thus interference is avoided.
  • Page 5 B. Wall Mounting the CL-A12 and CL-A16 CL-A12 CL-A16 (12” Analog Clock) (16” Analog Clock) 1. Mount both plastic anchors in the wall. 2. Insert the sheet metal screws (#10) through the mounting bracket into the plastic anchors. 3. Hang the clock on the mounting bracket. 4.
  • Page 6 Take the clock within close proximity to the CL-RFT Transmitter and power up the clock. If the clock is battery operated, remove the battery and put the battery back in again or press the Transmit/Receive button twice. If the clock does not correct, call Viking technical support.

  • Page 10 Can the CL-D2/4 digital clocks be used as an independent clock? No, the CL-D2/4 requires a communication input and must be used with a Viking Transmitter/Repeater (model CL-RFT). What will happen if the clock is not receiving a signal? The colon on the display will flash every second.
  • Page 11 If the wiring is correct, take a volt meter and measure the voltage. The voltage should be between 14 - 28 volts. What happens if the clock does not receive the signal? Take the clock within close proximity to the transmitter and power the clock. If the clock does not correct, call Viking technical support at (715) 386-8666.
