Control signal algorithm in pulse control mode
The command is a signal active front (signal transfer from the high level to the low level) at
any of the contacts at presence of the corresponding signal levels at the other contacts.
The following commands can be formed by sending a low-level signal to the contacts
“Unlock A”, “Stop” and “Unlock B” of the “XT1.L” connector block relatively to the contact
“GND”:
Always locked (locked for entry and exit)
Active front is at the contact “Stop” while there is a high level at the contacts “Unlock A”
and “Unlock B”. Both passage directions are locked at this command.
Single passage in the direction
А
(open for passage of one person in the
direction
А
)
Active front is at the contact “Unlock A” while there is a high level at the contacts “Stop”
and “Unlock B”.
At this command the passage direction
А
opens either for 5 sec. or until the passage has
been made in this direction or until the command “Always locked”, and the status of the
passage direction
В
does not change at that. The command is ignored if at the moment of
its receipt the status of the passage direction
А
is “Always free”.
Single passage in the direction
В
(open for passage of one person in the
direction
В
)
Active front is at the contact “Unlock B” while there is a high level at the contacts “Stop”
and “Unlock A”.
At this command the passage direction B opens either for 5 sec. or until the passage has
been effected in this direction or until the command “Always locked”, and the status of the
passage direction A does not change. The command is ignored if at the moment of its
receipt the status of passage direction B is “Always free”.
Bi-directional single passage (open for one passage in each direction)
Active front is at the contact “Unlock A” while there is a low level at the contact “Unlock B”
and a high level at the contact “Stop”,
or active front is at the contact “Unlock B” while there is a low level at the contact
“Unlock A” and a high level at the contact “Stop”.
At this command the both passage directions open either for 5 sec. each or until the
command “Always locked” is received. The command is ignored for the passage direction,
which status at the moment of its receipt is “Always free”.
Free passage in the direction

А
)
Active front is at the contact “Unlock A” while there is a low level at the contact “Stop” and
a high level at the contact “Unlock B”,
or active front is at the contact “Stop” while there is a low level at the contact “Unlock A”
and a high level at the contact “Unlock B”.
At this command the passage direction
А
opens until the command “Always locked” is
received; the status of the passage direction
В
does not change at that.
Free passage in the direction
