HKC Contact shows open zone

dec2000 · 04-03-2019 10:22AM #1

Hi all,

I have a HKC SW1070 alarm. We changed doors and the installer came back to refit the contact as there was a big gap between the frame and the door.

It worked for about a month but lately it’s acting up. These are the symptoms:

- If door is opened and then closed – when I try to set the alarm it tells me that zone is open.
- If alarm is set and door is opened, the alarm goes off (expected behavior). Unset alarm, close door, try to reset and it says the zone is still open
- If I tap the contact multiple times, the alarm will eventually set and it sees the zone as closed.

This happens every time the door is open. I’m assuming this is a faulty contact and needs to be replaced but just wanted to make sure there was noting else to check before replacing it?

Thanks

EDIT: thinking about since posting this - could the magnet be too far or not strong enough to reset the contact?

Could be the magnet not aligned properly. It could also be a faulty sensor on that device. The first thing I would try is disconnecting the inertia sensor & try with the contact only. is there any other devices on that zone?

If tapping the contact closes and opens the zone I think you have answered your question yourself.

No other devices on the zone, it's just the back door. Which ones do I disconnect (or leave connected) in the contact? Can take a pic later if it's easier? Thanks

yup, just wanted to make sure it's not something else or there are options before replacing

Post up a picture if you get a chance. Tapping a device will not confirm its the contact if there is also a shock sensor on the zone.

Id say you are correct if your prognostic is allowing you set and then not set the alarm.
You could test with a multimeter or disconnect either part of the sensor to see if the other works.
Usually if its a HKC sensor then there would be a loop between the first 2 terminals on the device. 6 in total.
1 and 6, outside terminals are the contact.
2 and 5 are the shock sensor.
3 and 4 are the tamper.

If so follow below.

Take out loop wire. If you have a cable going into 5 and 6 take this out.
Wire these into 2 and 5 to test the shock, make sure arrow on shock head is pointing up.
Wire into 1 and 6 to test the contact.

Always take a photo before disconnecting so you know you can put it back together.

Only getting back to this, was a too late in the evenings. Attached photos of the contact.

Will have a look at the cabling when the little one is less needy.

Is #1 over the spring? After putting the cover back on it showed the fault, so without opening the door, so could be the shock? If I wire 2 and 5 together, this should test this if I'm reading your response correctly?

1 and 2 look to have the loop as you look at the sensor.
The red and black are the tamper.
5 and 6 are blue and yellow going back to panel so that is what you are using.

Disconnect the loop in 1 & 2.
Disconnect 5 & wire into 1.
This will disconnect the sensor and leave the contact connected to see if that's working . (Is the arrow pointing up on that by the way?)
After that joining the blue & yellow together will disconnect the sensor & contacts & confirm to you the cable is OK.

Sorry, never got back on this and only got around to trying it earlier.

Disconnected the loop and wired 5 into poistion 1, and the contact is back working as expected.

So is it the shock that is now disabled? I'll end up getting a new contact but for the moment have left it connected as you said so I can set alarms without omitting zones.

Thanks for the guidance

Your welcome.
Just to double check is the sensor head aligned with the arrow pointing up?
If replacing , replace with a new combined sensor & contact for better security.

Sorry forgot to confirm that, yup arrow pointing up.

Change the whole unit so.
