Alarm Bell Tamper

DIY Vic

Hi,

I have a HKC SecureWatch 610 wired alarm (old enough now, but seems fine based on a walk test).
The keypad displays "Ext. Bell Tamper" and so I cannot arm the system.
I would like to just bypass this tamper from the alarm panel inside the house. I understand the consequences (i.e. if a burglar actually tampers with my external bell, the panel won't detect it), but I accept that, at least for the moment.
The panel circuit board has a set of connectors for the 6 zones at the bottom and another set of connectors to the right - these seem to be the ones related to the external bell tamper circuit. Unfortunately I don't know how the tamper circuit is wired because I can only see a Tamper Return connection on the panel.
The set of connections and wire colors on the right-top side of the panel (from top to bottom) are listed below:

Tamper Return = yellow
SAB Hold = blue
External Bell + = red
External Bell - (06) = black
Internal Bell + = red & white (2 wires)
Internal Bell - (05) = black & green (2 wires)
Arm/Disarm (04) / Alarm(03) / P.A. (02) / Fire (01) = all not connected

Can someone help me to bypass the external bell tamper error from the panel please?

These are the 2 that relate to the tamper on the bell.
Tamper Return = yellow
SAB Hold = blue

If you have a 4K7 resistor you can bypass this by taking out the yellow and put one leg of resistor in here, then other leg goes in with the blue in the BHO.

Many thanks Altor, I'll try to find a 4.7K resistor. I'll let you know if it worked.

No problem, if you have access to external bell there should be one located in there.

Thanks again Altor, that worked perfectly ... and now I even understand why.
I had to buy the resistor online as I didn't want to climb up to the external bell and Maplin has closed (ended up getting 20 of them), but the main thing is that it worked.
Much appreciated.

Brilliant, glad you got it sorted.
