Does anyone know how many PIR's can be connected in series together in one zone of Scantronic 9448EUR-90?

Thank you for your reply we found a problem with sounder circuit. Thanks again

I am trying to install Scantronic 9448EUR-90 board with two Takex MS100E multi pattern sensors connected in series on Zone 2 (all other zones are disabled) and Elmdene Quartz 1000live sounder. My problem is that control panel shows temper fault - all boxes are closed, all cable connections verified. If I reset the panel by disconnecting battery and main supply the temper light will go off Zone 2 light will go on and when you try to set the alarm with users code the temper lights come up on again. Could somebody recommend how I can solved the problem?
