* 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.
3 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.
