Hikvision DS-KD8003 PoE

[Dacmoreira]

I have a DS-KD8003, and apparently everything is working fine on the inside display and camera.
But when I press the button for the electric lock, the gate opens but the external device turns off, and restarts.

What could it be?

Does the voltage being supplied to the "external device" drop significantly when the button is pressed?
Is the electric lock the correct one for the applied voltage?
Is there a diode clamp installed across the coil of the electric lock?

Question 1: I have one Ubiquiti PoE+
Question 2: i think so.
Question 3: what it is?

Question 3: what it is?

1. I ask because it sounds like the voltage dips enough when the electric lock is energized to cause a restart of the other device.
2. Just to be sure I would check ratings for the device from a label or part number.
3. When an energized coil is de-energized it can generate a big and backward voltage spike that can damage a semiconductor output. The diode is placed across the coil with its cathode (the white band) to the positive side of the DC coil to clamp that voltage and protect the output driver. It can also be incorporated inside the device where it's not visible.

It's likely that the manufacturer took this into consideration and the output is protected. It may also be a "dry" relay closure output which can negate the need for a diode clamp. I cannot say for sure, not having the installation instructions / user manual.

Does the manual have info regarding the electric strike, such as its operating voltage and if it requires an external 12VDC or 24VAC power supply to operate the lock / strike?

This is the electronic lock!
