My wifes been decorating and removed the cover of a pir sensor. Alarm went off as it should. However after replacing cover the alarm wont set and keypad displays check hall PIR. I have come across these snapped wires to what im guessing is a resistor. Can anyone tell me what exactly this is and where to source from. Ive tried swapping it out for an unused one. The "resistor" I replaced had SO3 marked on it and the "resisitor" I swapped it to was marked s10. This hasnt fixed my issue. Can anyone help?
