• Fuse has blown.
• 24v power supply not functioning.
• Verify the power is ON at the circuit breaker.
• Inspect fuse on primary power terminal block.
If blown, contact Alvarado for replacements.
• Meter power supply output. If 24v is not
present, replace power supply.
• Turnstile fans are on but no
Open / Close or Status Lights
and arm will not lock back
into place

are dim.
• Light boards are unplugged

board. Ensure both are properly secured.
• Arm does not lock into
position upon boot up.

• Valid credentials do
not activate turnstile.
• Access control leads connected to
wrong terminals.
• Verify access control leads connect to the
appropriate terminals.
See terminal listing on Page 12.

buttons to simulate activations. If test buttons
do not activate, replace control board. See
Page 11 for button location.

passage is completed.
• Anchor bolts are loose.
• Check anchor bolts. If loose, tighten bolts
to 20 ft-lbs using a torque wrench.
• Arm does not fully return to
home position
• Home position needs calibration.
• Re-home the arms back to correct position.
See Appendix A on Page 25.
• Arms continue to rotate
after a passage.
• Double activation provided.
• Advise patrons to swipe their credentials
only once to prevent double activations.
• Drop arm does not lock
back into position.
• Foreign matter stuck in drop-arm
mechanism.
• Drop arm solenoid is defective.
• Ensure drop-arm mechanism is free of
debris.
• Power on turnstile, lift arm to lock position.
If it does not lock into position, replace the
drop-arm solenoid.
Contact Alvarado for replacement components.
