CL Series
Wireless Analog / Digital
Clocks and Accessories
August 23, 2017
Specifications
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).
