Functions on the Extension Unit EXB
5.4.1
Inner Impulse
Inner impulse will open the door if Program Selection is set to AUTO or EXIT and
keep the door open during the hold open time.
The hold open time is adjustable from 0 to 30 sec.
5.4.2
Low Pass Filter (automatic cycle delay)
This function is used in Europe for handicap individuals who want to use an auto-
matic door. This function requires the individual to push and hold or maintain the
inner
impulse signal for a specified amount of time to automatically open the door.
The time can be adjusted from 0 to 5 sec.
5.4.3
Presence Impulse Approach, Door Mounted
Presence Impulse will prevent an open door from closing and will re-open a closing
door.
Presence impulse is ignored when home impulse is active.
Presence impulse is ignored if the door is manually opened.
Presence impulse is not ignored if the door is opened with Push to Go.
The input can be either “normally open” or “normally closed”, which can be selected
through a function selector jumper (Presence Impulse NO/NC).
5.4.4
Presence Detection Swingpath, Door Mounted
Presence Detection prevents a closed door from opening and stop a door from con-
tinuing to open.
A switch can be used to blank out / inhibit the sensor from detecting a wall or object
close to the open door. In addition, a second switch can be added to extend the inhibit
zone.
Two LED’s indicate the blank out/inhibit switch status. One LED for the master door
and one for the slave door. The LED will illuminate if either of the two blanking/
inhibit switches are activated.
Presence detection can be selected through two function selectors jumpers, “Presence
Detect Master” and “Presence Detect Slave”.
