LINELOCK INPUT
Required if Low Frequency Fluorescent Lighting is utilized in the installation
The T-
DAR™ system requires an input of low voltage AC from a source that also
supplies the lighting for the installation (as shown in the diagram below). This low
voltage (6 to 30VAC) AC signal is required to allow the cameras to be in sync with
the low frequency fluorescent lighting. Failure to provide this signal to the T-DAR
may cause erratic behavior in the system.
Any 6 to 30VAC signal will provide the required synchronization of the T-DAR to the
low frequency fluorescent lighting. A small transformer is provided with the T-DAR
system and can be used to provide this signal; in addition, any other source of low
voltage AC (6 to 30VAC) that is available can also be utilized. Low voltage DC will
not provide the required LineLock signal; use low voltage AC only.
CAUTION!
Do not provide 110/220 VAC to the T-DAR unit LineLock input. This will damage the
unit.
About Fluorescent Lighting:
Older style fluorescent lights turn on and off the light output at the AC line frequency: 50 or 60 Hz-depending on the area of the
world. Since cameras operate at a similar frequency, this rapid cycling on and off of the lights can cause erratic behavior in the
T-DAR cameras and requires synchronization.
Newer style high frequency fluorescent lights operate at much higher frequencies than do the T-DAR cameras and do not
affect the T-DAR cameras; no LineLock signal is required.
