Model Number: K220+R502-A Power supply: DC10V--24V Stand-by mode current: less than 10mA Fingerprint capacity: 200 Output: Relay(Max. current: 10A) Model: K220 Relay Time: 0.5s-60s or over 60s - In normally open mode-press finger-relay open,press again-relay closed Note: 1. All indicator lights are off in standby state, and the lights are on in working state; 2.If want to close the module indicator light when in the normally open mode, long press any SET button to hear long "Di" beep three times. Repeat this action to open.
