2.2 System Operation and Startup Sequence
The SiteSync IQ system receives atomic time information from Ethernet. The system
controller is a powerful multitasking device that is capable of sending precise time
information to synchronize all the system wireless clocks and accessories. The system
can be monitored and programmed from the SiteSync IQ system controller keypad or via
a PC web browser with Remote Connect capability. It’s important to follow steps in this
order: install system controller, confirm signal reception and then install clocks.
Wireless System Controller Operation:
When power is first applied to the SiteSync IQ system controller, the user shall
complete the Startup Wizard to initiate system operation and signal transmission.
The SiteSync IQ system controller looks for the time signal every hour from the
time source your system is designed to synchronize with. Once the system
controller has received the time synchronization it sets its internal clock to that
time. The system controller then starts to transmit the internal time. The system
controller features an on-demand Ethernet sync capability that is initiated by the
user/installer to sync the time.
Analog Clock Operation:
For AC powered analog clocks, apply AC power. There is no need for any
additional adjustment (the clock movement adjustment is fully automatic).
After a few seconds of initial setup, the clock receiver will look for valid time
transmission. The monitoring LED at the back of the clock will flash red during
that period of time. After a valid time data is received, the monitoring LED will turn
green and ultimately stop blinking when the clock begins the correction or
synchronization period. The clock will automatically look for valid time signals four
times each day, and will adjust to the correct time if needed.
Digital Clock Operation:
Connect the digital clock to the120 VAC power source. After several seconds of
initial startup, the clock receiver will look for a valid signal transmission and
synchronize to the correct time as soon as it receives a valid time from the
system controller.
Note: Refer to system installation and operation manual for wiring instructions
and mounting.
