You’re encountering various red LED signal patterns on a Salto door lock, each red indicating a different status or error. According to the Salto door lock user manual, here’s a breakdown of what each red signal means and what actions you can take to address the issue:

1. Flashing Red LED (5 times) with Multiple Beeping Tones

• Issue: Key rejection due to the Privacy Deadbolt being engaged. The user does not have permission to override the deadbolt.
• Solution:
  • Use a key with privacy override enabled.
  • Grant the user Privacy override permissions.
  • Check for possible lock installation errors.

2. Solid Red LED with Multiple Beeping Tones

• Issue: Invalid access. The user cannot access the door or zone during the attempted time frame.
• Solution:
  • Read the key and verify access permissions for that door and time frame.
  • Update the lock using the portable programmer (PPD) if access permissions are correct and the key has been updated.

3. Red LED and Beep Occurring 6 – 20 Seconds AFTER Door has Been Unlocked

• Issue: The door is re-locking.
• Solution: Present the card again to open the door.

4. Green LED with Immediate Red LED and Beeping Tones

• Issue: End of office mode. The lock has returned to standard mode, requiring a valid card for access.
• Solution: Check the mode of the door setting in the Salto software if there is an issue. The office mode has been disabled.

5. Red LED Flashing 4 Times Followed by 1-Green Flash and Beeping Tones

• Issue: Low batteries. The lock is a warning that the battery is very low.
• Solution: Replace the batteries and update the lock using the PPD. Inform maintenance to address this.

6. 3-Intervals of Orange/Yellow LED Followed by 1-Red LED Flash

• Issue: Card not correctly read (key removed before the reading process has been properly finished).
• Solution: Try keeping the card on the reader again until the LED stops flashing.

7. Very Short Red LED Blink

• Issue: The card was removed too fast before completing the reading process.
• Solution: Place the card on the reader until the LED stops flashing, and try to access the door again.

8. Delayed or Slow Red LED

• Issue: Not an authorized Salto card format. Possible use of an aftermarket key card or one from a third-party vendor not certified by Salto.
• Solution: Contact Salto technical support for assistance with card format issues.

For all these scenarios, it’s essential to consult the Salto door lock user manual or contact Salto technical support for further assistance, especially if the problem persists after you’ve taken the recommended actions. Also, ensure that only authorized personnel troubleshoot and maintain security devices.
