Roller garage door contact

Yes take the wires out stick probes in 2x alarm terminals of the door contact and set to ohms

Shows around 0.000ohms when closed and open is open so looks to be working fine

Read that wrong lol. So if u wire it up and meter the red and black from the cp do u get 2k2 closed and 6k9 open?

From engineering go to diagnostics
Press yes, then no until wired devices yes,
View inputs yes then press no until keypad inputs,then yes.
What is showing F,O,C ?
F fault
O open circuit
C closed circuit

Sorry for the late reply, i attempted this again today and it shows Open circuit, I have attached some pictures ( note that I just realised I didn’t put a 2k2 resistor in but dont think this should be the problem right?)

Blue goes to - on keypad
Green goes to Z2

can you confirm reds are tamper pair and whites are alarm pair?
Does look OK from photo.Do you have multimeter? Check pair blue/green go from door to keypad and wired as diagram.

Yes as attached

Yes how should I test?

 

[Theweeknd]

Any ideas anybody?

That’s not a 2.2k resistor ! In the junction box ….looks like a 6.8k resistor

I know I mentioned that earlier, but would this have an effect on it being open circuit?

 

[sparkymarka]

Yes

 

[Theweeknd]

Yes

Changed and now doing the opposite, staying closed not opening when moving the magnet

 

[Handymanjo]

If you have multimeter
Set to ohms
Across blue/green in junction box with magnetic closed on contact you should have 2.2k
Remove magnetic you should have 6.8k
That proves contact is wired and correct.
May need to check cable from door to keypad.
If still not working wire contact on short fly lead directly onto keypad.
If still not working the programming issue.
The above should prove one way or another if correct .

U also said the door contact was wired on to z2 on keypad ? Have u changed this ? How many keypads u got. Also if you press yes when in the keypad diagnostic menu it will show u the zone resistance so see what it is open and closed

If it measures zero ohms does this mean the sensor is fault? i even used a short wire at the keypad and still didn’t work, tested the cable running to garage by linking it and it works fine.

Im just going to return the sensor!
