hi i have really big problem 2 years ago the alarm was installed at my house and now one of the sensor has come off from its orignal place and its hanging this has caused the control panel to lock down i think and the temper light is flashing red. I need to use the alarm today and i have been trying to reset it but have failed. I read on other forums that engineer code is required to reset the contol panel. I have the code but i don't know how to put it in so i am hoping someone could help, the engniere code i got was 1234
