Hardware Options
The Airlock feature is supported and built into the firmware of NXT Mercury Powered
and Mercury controllers. It requires the use of door contacts at each participating doors
and can be setup between two doors on the same controller. The general principle of
this feature is that you cannot get access through one door while the opposite door is
open.
The Anti-Passback feature is supported on NXT Mercury Powered controllers, Mercury
controllers and PXL controllers. The PXL controllers support local Anti-Passback - mean-
ing the rules are set on a per controller basis (controllers cannot keep track of what read-
ers cardholders have used on other controllers.
The Mercury and Mercury Powered controllers also offer Global Anti-Passback when
using the optional add-on Global Linkage module. Using Global Anti-Passback the sys-
tem can keep at track of the APB status across all or a selection of controllers.
Dual Verification, or Card + Pin is supported on all the Wiegand controllers that are com-
patible with Doors.NET. The feature is easy to setup and can be applied to doors at cer-
tain times of day or via a mode change remotely from the software. It is designed for high
security areas and applications and individual users can also be granted 'exempt' status
which will allow them access at any time without ever requiring a secondary ID.
The Elevator Control feature allows you to control up to 10 floors from a single 2-door or
20 floors from a single 4-door controller with an NXT 4x4 module wired into each of the
RS-485 ports. Or up to 128 floors can be controlled when using NXT-GIOX units. A max-
imum of two GIOX units can be used on a controller, but when fully populated with NXT
Output modules each will give you 64 floors, making it an extremely cost-effective elev-
ator control solution.
