Why Alvarado Turnstiles do not unlock?
Several factors can prevent an Alvarado turnstile from unlocking. It could be due to: * Lack of power: For Fail-Lock units, ensure the ON/OFF switch is ON, the fuse is functional (replace if needed), and the LED on the control board is lit. Verify proper voltage (110-120VAC) to the junction box and approximately 10 VAC from the transformer to the control board. * Missing activation signal: Confirm the access control system is correctly connected and sending the right signal to the turnstile control board. * Faulty lock arm spring: Replace any missing, broken, or worn-out springs with Alvarado-specific replacements. * Sticking lock arm: Clean and lubricate the lock arms; adjust the hydraulic closure if required. * Defective solenoid: Test and replace the solenoid if necessary. * ...
What to do if Alvarado EDC do not re-lock?
If an Alvarado turnstile fails to re-lock, several issues could be the cause: * Power supply: For Fail-Safe units, check that the ON/OFF switch is ON, the fuse is intact (replace if needed), and the LED on the control board is illuminated. Ensure proper voltage (110-120VAC) is reaching the junction box and approximately 10 VAC from the transformer to the control board. * Optical sensors: Clear any obstructions from the optical sensors and tighten their mounting screws to ensure proper alignment with the turnstile rotation tabs. * Faulty optical sensor: Repair or replace the optical sensor assembly. * Lock arm spring: Replace any missing, broken, or worn-out springs. Use only springs purchased from Alvarado. * Defective solenoid: Test and replace the solenoid as necessary. * So...
