NEW in 2022 Spirals: Smartsurround™ light curtains and CAN bus cabling
Two new features have been added to Spirals in 2022,
both of which change the installation process.
CAN bus cabling
The CAN bus system simplifies cabling
and minimizes internal field wiring during
installation. the system works this way:
▪
CAN bus cabling
is a single chain (series) of
cables
that connect ALL CAN-enabled devices
to the controller.
▪
The cabling starts at the controller
and runs
through the CAN repeater box at the base of
the non-drive side side column, then across
the rear spreader to the CAN repeater box in
the head assembly, then
terminates at the
CAN distribution box
at the base of the
drive side side colum.
▪
CAN-enabled Rytec devices
can plug into any
available port in any CAN box
. For example,
the CAN-enabled BTA4 user terminal plugs into
a baseplate port when preintalled on the side
column, or a head assembly port if it is field
installed remotely from the door.
▪
Ports must be jumpered
if they are not
connected to a device so that the signal path
remains unbroken until it terminates at the
distribution box.
SmartSurround™ light curtains
The SmartSurround™ light curtains replace the
Pathwatch LED strips, and combine the function
of a light curtain and an alert system.
▪
Spiral doors now have
three light curtain
detection planes
. The front SmartSurrounds™
are mounted on the side column covers.
The rear units are field installed on the
walls of the door opening.
▪
The LEDs are larger and brighter than the
Pathwatch, and display a sequence of lights
that move up and down when the door opens
and closes, and that flash repeatedly whenever
any of the detection planes are broken.
