Program the vestibule sequencers to pair with the transmitter.
Repeat these steps for each vestibule sequencer and transmitter pair.
A. Press and release the programming button on the vestibule sequencer. The LED will change from red to solid green,
This indicates that it is ready to learn the transmitter signal.
B. Press and release the transmitter button and confirm that the vestibule sequencer’s LED changes from green to red.
This indicates that it is learning the signal from the transmitter.
C. After 3 seconds, press and release the transmitter button again and confirm that the vestibule sequencer’s LED flashes
green several times. This indicates the end of the learning procedure. When complete, the LED will change to solid red.
Program the vestibule sequencer how long to wait before signaling the door to open.
Repeat these steps for each vestibule sequencer and transmitter pair requiring a timed delay before activating a door’s
operation. NOTE: In a typical two-door application there will be no time delay in the signal to open the first door.
A. Press and hold the programming button on the vestibule sequencer connected to the second door for 6 seconds and
release. Confirm that the LED is solid red. This indicates that it is ready to learn the time delay.
B. Press and release the transmitter and confirm that the vestibule sequencer’s LED changes to solid green. This indicates
that it is waiting for a second signal after the desired amount of time has elapsed.
C. When the desired amount of time has elapsed (up to 4 hours), press the transmitter again and confirm that the LED
flashes green several times. This indicates the end of the learning procedure. When the procedure is complete the LED
should change back to solid red.
D. In a two-way traffic application, there would typically be two transmitters (wall switches) – one for egress and one for
ingress. The Larco vestibule sequencer will recognize when to delay the opening depending on the unique signal
from the individual transmitters. In this application, repeat step 2 in the opposite traffic direction.
Test the system to confirm the operation.
A. Press the transmitter and walk-test your installation to confirm that the time delay you programmed is appropriate for
the application. The first door should begin its opening and closing sequence immediately upon activation of the
transmitter. The second door should begin its sequence after the chosen time delay.
B. If you need to change the time delay, simply repeat the instructions in step 2.
Programming Procedures
Follow the the appropriate set of instructions below to program each vestibule sequencer in your installation.
NOTE: The vestibule sequencer’s single programming LED changes color (green or red) and either glows steadily or flashes to
indicate various programming operations. Before you begin the programming procedure, check to see that the sequencer’s LED
glows red, indicating that power is connected.
Deleting Programming Procedures
You can clear the sequencer of all previously learned
transmitters. Press the sequencer’s programming button for
more than 8 seconds until the sequencer’s LED starts blinking
green. Release the programming button. The LED should now be
solid red. The sequencer’s memory is now cleared.
433 MHz Vestibule Sequencer
Installation Instructions
(cont.)
The sequencer and transmitter comply with FCC part 15/15.231, Industry
Canada RSS-210, EN55022A, EN55024, EN300-220-3, and EN301-489-1.
Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any inerference
received, including interference that may cause undesired operation. This
product may be susceptible to local transmissions being generated near the
transmitter’s fundamental frequency. Testing has shown some susceptibility
in a frequency range of 416-440 MHz.
