Features:

• Compatible with DC10V-120V voltage range;
• Three verification methods: fingerprint, IC card, mobile phone NFC
• Three control modes can be switched: jog mode, self-locking mode, ignition mode;
• In the jog mode, the output time can be adjusted, and the output can be up to 15 minutes;
• With relay normally open and normally closed output control.
• IC card/NFC sensing distance: ≥25mm
• Can be connected to the exit button

Three control modes:

1. Inching mode:turn on after fingerprint recognition; automatically turn off after releasing the finger and reaching the set delay time.
2. Self-locking mode:turn on after recognizing the fingerprint; after releasing the finger, it will be disconnected immediately after re-identifying the fingerprint.
   
3. Ignition mode:keep the fingerprint recognition unreleased; it will keep on all the time, and it will disconnect immediately after releasing the finger

 LED Legend (Fingerprint Module)

• Green = Action succeeded (enrolled / deleted / verified)
  
• Red = Failed verification
• Yellow = Add admin fingerprint mode
  
• Pink = Add regular (user) fingerprint mode
  
• Flashing Yellow = Delete a single admin fingerprint
  
• Flashing Pink = Delete a single regular fingerprint
  
• Flashing White = Delete all regular fingerprints (admins remain)
  
• Blue (panel LED) = Relay control mode indicator
  

Relay Control Modes (Panel Blue LED)

• 1 flash = Self-locking (toggle)
  
• 2 flashes = Jog (timed pulse)
  
• 3 flashes = Ignition (hold)
  
• Jog-Mode Delay (Red LED Blink Count → Time) 

To adjust:

1. Power OFF the board.
   
2. Hold SET button.
   
3. Power ON while holding SET.
   
4. Release SET when panel red + blue LEDs turn off.
   
5. Short-press SET to cycle delay (red LED blink count = time):
   1 =300 ms
   2 =600 ms
   3 =1s
   4 =2s
   5 =3s
   6 =4s
   7 =5s
   8 =10 s
   9 =60 s
   10 = 15 min
   
6. Save by touching a valid fingerprint or card.
   

 Fingerprint Management (Admin Finger Required)

• Add admin fingerprint: From factory: touch any finger ∼5 s → Yellow →
  press/release same finger 4–6 times until Green.
  
• Add user fingerprint: Hold admin finger ∼10 s → Pink → release; press user finger (Blue then Green).
  
• Delete a single admin fingerprint: Hold admin finger until Flashing Yellow →
   release; touch admin finger to delete (Green).
  
• Delete a single regular fingerprint: Hold admin finger until Flashing Pink →
   release; touch user finger to delete (Green).
  
• Delete all regular fingerprints (admins remain): Hold admin finger until Flashing White → release; confirm to wipe all regulars.
  
• Factory reset (everything): Power ON, hold SET >10 s until panel red LED +
   module white LED → release.
  

Demo Mode (Important)

• After deleting all fingerprints, the device enters a demo mode:
  
• Any fingerprint will open the relay.
  
• The module still flashes Red to indicate it is not a stored fingerprint.
  
• This continues until at least one admin fingerprint is enrolled.
   

Card / NFC Management

• First card after reset = Admin card.
  
• Add user cards: admin card ∼5 s → beeps → present user cards.
  
• Delete one card: admin card ∼10 s → beeps → present card to delete.
  
• Delete all cards: admin card ∼15 s → beeps → all cleared.
