* The matching of wire sizes to equivalent wire gauges are only approximate.
** Recommended cable types for opmal HBUS RS485 performance.
*** Not applicable for PIV or Alarm Terminal installaons.
Notes:
• Shielded cable may reduce the obtainable cable length. Shielded cable should be
grounded at the Controller end only.
• If other cable types are used, operang distances and performance may be reduced
depending on the cable quality.
• The recommendaon for opmal performance is up to 20 T20 terminals can be connected
to one Controller 6000. Of these 20 terminals, up to 4 could be congured for alarm zone
(or fence controller) management.
A terminal is congured for alarm zone management when it has either Alarm Zones
congured on the Alarm Zones properes page or items congured upon its mimic panel.
