Xem access controller question

Does the controller put out power for as long as the chip is being read? And does the led show when power is going through the white wire or only when the read is valid?

The led lights when a valid chip is present (for the entire time it is present) the same as the output, it is high +12v while an authorised tag is in range.

Probably the best way to think about it is that the output is high (12v) when a valid tag is in range, the led is illuminated at the same time the output is high.



The LED lights when a valid authorized tag is being read, hence when power is flowing in the white wire.

Interesting. Thanks for the response
