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.

The invention provides both a visual and aural warning if a user attempts to raise the pop-top roof when one or more of the locking latches has not been released. Sensing of the position of the roof locking latches is provided by magnetic proximity devices installed adjacent to each roof locking latch.Fig.1 Fig.3FFig. ULCKEDT M11R~siM M NMliWllilililii2|.... !.......
