* The matching of wire sizes to equivalent wire gauges are only approximate.
** Recommended cable types for optimal HBUS RS485 performance.
*** Not applicable for PIV or Bluetooth® enabled reader installations.
**** Tested with 13.6V at start of cable.
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, operating distances and performance may be reduced
depending on the cable quality.
•
The recommendation for optimal performance is up to 20 T30 Keypad Readers can be
connected to one Controller 6000. Of these 20 terminals, up to 4 could be configured for
alarm zone (or fence controller) management.
A terminal is configured for alarm zone management when it has either Alarm Zones
configured on the
Alarm Zones
properties page or items configured upon its mimic panel.

Distance between readers
The distance separating any two proximity readers must not be less than 200 mm (8 in) in all directions.
When mounting a proximity reader on an internal wall, check that any reader fixed to the other side of
the wall is not less than 200 mm (8 in) away.
