Alarm out signal questions

[shiraz]

Hi All,

Hoping I can get some queries resolved regarding the alarm out connections.

My camera is HikVision AcuSense DS-2CD2386G2-ISU/SL. It has (IN, G, 1A, 1B) connections

I'm trying to figure out how Alarm Out signal works.

In one thread somewhere I read that when alarm out triggered it will short circuit GND and 1A pins. Reading in another post it seems like 1A and 1B would be shorted together.

I've put a voltmeter and ohm/connectivity meter across these ports and the results are:

| V | Connectivty |
-----------------------------------------------------
1A | Gnd | 0 | Open circuit |
1B | Gnd | 0 | Open circuit |
1A | 1B | 0 | Open circuit |

It appears the alarm out is not at all working. I'm triggering the alarm out via the web gui of the camera and I can hear a 'click' sound from the whenver I trigger alarm out or clear it

Please help

Thanks,

Shiraz

Alarm output is 1A -1B it should be short when triggered.

Alarm output is 1A -1B it should be short when triggered.

Thanks for your help. It worked

It wasn't registering on the meter probably because its just a pulse.

Alarm out indeed shorts 1A and 1B
