I have just installed a new external bell/strobe unit. When I got to set the control panel(aritech CS350) I keep getting a open zone Bell tamper indication. The engineer link on the bell unit is dicsconnected. It has two siren units - if I disabled one would this sort the problem out?

What bell is it? And when you say 2 bells, 2 separtate bell boxes ?

What make of bell is it and explain how you have wired it.

On Aritech systems you need to wire the bell correctly and also not forget the EOL resistor for the tamper, If you have not worked on these panels before the best thing would be to get a local installer in who knows the panel.

It is an Elmdene, Hexidin. With two siren units in it. Yellow strobe wire to ST-, Red supply to H+, Black supply to H-, Blue trigger to R-, Green tamper to TR and a loop from TS to H-.

Thanks

Wheres the EOL resistor connected to ?

There is no EOL resistor on the panel terminal block where the bell tamper loop wires come in. However there is a resistor on the bell unit block between TR and H- I think.

Hope this make sense.

Fitted my first Hexidin today - everything fine at lunchtime, 2000hrs off goes a bell tamper - hope we don't have a product problem here.

Was yours new out of the box?

Yep. All new and shiney!

hope this is a coincidence.

I'm going to ring their tech support tomorrow so I'll let you know the result.
