The MorphoAccess Sigma Wave 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 Wave
terminal timeout value, must be adjusted to a value a little bit higher than the maximal
value of the controller response time.
Warning: if the LED2 wire is connected, it must be constantly maintained in the high
state.
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 Sigma Wave terminal considers that:
The answer of the controller is "access granted", when the controller puts the LED1
wire to the low state (by closing a contact between the LED1 and the GND wires),
and leaves the LED2 wire to the high state.
The answer of the controller is "access denied", when the controller puts the LED2
wire to the low state (by closing a contact between the LED2 and the GND wires),
whatever is the state of the LED1 wire.
The MorphoAccess Sigma Wave terminal also considers that the answer of the
controller is "access denied" in case of time-out while expecting for a closure between
LED1 and GND wires, or between LED2 and GND wires.
