Figure 4.1 (b) Connection to the EverAccess reader using Wiegand format

Each door module can provide +12V voltage for two card readers.

Twisted cable is recommended to connect the controller and card readers. The

maximum transmission distance between the reader and controller depends on the

gauge of the cable and the specification of the card reader. Please read the reader user

manual carefully before installing the cable for the readers.

Note: When installing a multi-reader system, it is strongly recommended that

all the card readers follow the same format, i.e. all of them are EverAccess

RS232 or Wiegand. Multiple formats could present compatibility problems: a

card may not be accepted by all the card readers in the system.

Connection to Door Lock

Each door module provides an interface to two door control relays. Terminal 11 ~13

are for door 1 and terminal 27~29 are for door 2. Terminal 12 and 28 are named

common terminal (COM). Terminal 13 and 29 are named normally closed terminal

(N.C.). Terminal 11 and 27 are named normally open terminal.

The electrical door lock must have a separate power supply. The power supply for the

electrical door lock depends on the specification of the lock. Carefully choose the

cable connecting the door locks to fit the current draw. Two common types of

electrical door locks in the market are electric strike locks and magnetic locks. The

connection methods for these examples are shown in Fig. 4.2 and 4.3 respectively.
