GROW K212 Fingerprint Control Board Classification Fingerprint Control Board Power Supply DC8--30V Stand-by Mode Current 40mA Fingerprint Capacity 200 Output ±DC5V,300mA Interface Usage P1：Power supply，Input voltage: DC8--30V，Input current: 0.3A P2：Relay output P3：Active Signal of open door，Voltage DC12V(Input) P4：Fingerprint module(Input) P5：Micro-motor(Output) P6：Button for opening door, closing signal(Input) Adjustable resistance: Setting closing time for relay Technical Parameters ·Power supply: DC8--30V, ·Stand-by mode current:40mA ·Fingerprint capacity: 200 ·Interface output of motor: ±DC5V,300mA ·Interface output of relay: 3A Operation Instruction 1. System on working state, indicator light(LED) flash slowly. 2. Press SET button, system in register state and indicator light flash fastly. 3. Fingerprint can be registered continuously when system in register state; if no need for adding fingerprint more, exit after waiting 5 seconds or by press SET button; 4. When back to factory default, press RESET button until hear“Di”, release the button, hearing “Di” long beep means operation successful; 5. Fingerprint verified or the button for opening door closed, the relay actuated, the relay time can be set by adjustable resistance,setting time: 0.5-9 seconds;Motor interface output DC5V and keep 0.5 seconds; stop 5 seconds, then minus voltage outputted and keep 0.5 seconds.
