Problem With Sabb External Sounter

[Guest aka_alex]

Hi all,

I have just installed an Aritech CS235 wired system to my house with an SABB External Sounder. When I try to arm the system I keep getting an external tamper error on the keypad display and the strobe on the sounder flashes constantly. I have wired the box as per the instructions that came with it and wired it back to the control panel as follows

Tamper to Tamper (through 47k resistor in box)

Int Bell + to Strobe +

Int Bell - to Strobe -

Ext Bell + to Ext Bell +

Ext Bell - to Ext Bell -

Bell Hold Off to Hold Off

As far as I can see I have wired it correctly. I have run a diagnostics on the panel and it doesnt show any faults and have reset all logs etc as per instructions. Can anyone offer any advice on rectifying this problem.

Many Thanks
