The controller supports neither LED1 nor LED2 signals
When the access controller has no relay contact to provide an answer to the
MorphoAccess® terminal, then the decision to emit either the “access granted” signal
or the “access denied” signal is taken by another way. It is either the MorphoAccess®
terminal itself that decide, or it waits for the access controller answer through the
local area network (TCP), or on the RS-485 serial port.

It is strongly recommended to disable the LED IN feature, to avoid any interference

on MorphoAccess terminal behavior.
The controller supports only LED1 signal
When the access controller has only one relay contact which is dedicated to the
“access granted” answer, this one must be connected between the LED1 and GND
wires. The LED1 wire is set to the low level by closing the contact between the LED1
and the GND wires, and it means “access granted”.

The MorphoAccess® terminal uses the timeout of the wait for a low level on the on
LED1 wire or LED2 wire as “access denied” answer.

To minimize at most the waiting time of the user, the MorphoAccess® SIGMA Lite
Series terminal timeout value, must be adjusted to a value a little bit higher than the
maximal value of the controller response time.

The controller supports LED1 and LED2 signals
When the controller supports one relay contact for each of the possible answers

then:
The « access granted » contact must be connected between the LED1 and the GND
wires of the terminal
The « access denied » contact must be connected between the LED2 and the GND
wires of the terminal.
The MorphoAccess® terminal considers that:
The answer of the controller is "access granted", when the controller puts the

wires), and leaves the LED2 wire to the high state.

The MorphoAccess® terminal also considers that the answer of the controller is

GND wires, or between LED2 and GND wires.
