Control Board Description
Signal Inputs and Outputs
To / From Access Control
System
Inputs - J4 Terminal Block
Signal inputs from access control
systems are wired into the EDM’s
I/O input terminal block. There
are two types of input signals,
momentary dry contacts (MDC)
and sustained dry contacts (SDC).
All input signals must be normally
open (N.O.), voltage-free, dry
contacts. MDC’s must be greater
than 100ms in duration to register.
The suggested MDC input duration
is 1 second or less to support
rapid throughput in high volume
applications.
Outputs - J5 Terminal Block
Signal outputs are available from
the EDM’s I/O output terminal
block. Outputs are normally open,
voltage-free, momentary dry
contacts. The output signal length
is 500ms in duration.
NOTE
NEVER connect signal lines
containing voltage directly to the I/O
terminal strips. This will damage the
circuit board.

The test buttons on the control board, ENPASS and EXPAS, are
used to simulate a valid credential activation [Fig. 9].
• ENPASS is used to simulate an activation in the CW direction.
It is located in the bottom left corner.
• EXPASS is used to simulate an activation in the CCW direction.
It is located above the J4 terminal block.
