If I then fill the tank above the alarm threshold, cycle the gear a few times so it drops below, the alarm does not trigger. I can't figure out why, it's like it needs to be reset?

If I have sufficient air pressure in the tank when the plane is turned on, there is no alarm ( expected), then if I cycle the gear below the 370kpa, the alarm will trigger. If I top up the air and cycle gear again dropping below the 370kpa, the alarm will NOT trigger.

I'm assuming I have to assign a reset switch and that it will not reset itself? So once an alarm has been triggered, it must be reset manually?

Thanks
