my lp1 4000 make unknown is making 3 beeps from a hallway sensor?

What type of sensor is it? Is your alarm a wired or a wire free system.

If it is a wire free system - (I have not heard of your model). It would indicate that a detector battery would require replacement - how ever your alarm panel would indicate which zone or circuit detector it is. Then you simpy need to replace the battery. I been to faults in the past to beeping and it turned out to be the property smoke detector.

Further investigation and information required please
