CHAPTER 5
Reader Interface
The DirecDoor reader interface provides:
•
four (4) supervised Device Inputs (DI)
–
two (2) alarm DIs and
–
two (2) exit DIs,
•
two (2) reader LED outputs, and
•
two (2) door strike DO relays.
Note:
The DDSDC supports only one door strike DO relay, one alarm DI, and one exit DI on
Connector J2.
The reader voltage is 12 VDC only.
The reader interface is limited to only one type of reader technology:
•
Wiegand,
•
F/2F, or
•
Supervised F/2F.
The reader interface has built-in pull-up resistors to accommodate cable lengths over 500 feet
(152.40 m). External pull-up resistors are not required for the reader interface.
In Supervised F/2F mode, the DI (alarm point) is available at the reader or at the controller on
Supervised F/2F readers that support DIs and Exit DIs.
