Caravan Automatic Latch Monitor (CALM) device monitors all the roof locking latches on a pop top or similar type caravan. The CALM device warns both visually and aurally if one or more roof locking latches are not in their full unlocked position when the crank door hatch is open. The CALM device will signal visually when it is safe to raise the caravan’s roof. Additionally, the CALM device will indicate when the caravan's battery voltage falls below a set point (typically around 11.7 - 12 volts) to indicate that the battery requires recharging.
