Sorry can't do paragraphs on my phone... Any ideas truly appreciated... We moved into our house in September and have never known the alarm code, and never planned to use it because of our big dog. So it's been ignored completely, until this morning a power cut has set off a constant high pitched noise, not that loud but very annoying. We've had power cuts in the past with no problems. The TPR light is flashing and it's an Intellisense alarm, C023-203 is the only number I can see on it, not sure if this is a model? Thank you.
