Beschreibung
Zusammenfassung:	Methods and systems for detecting event based on current and/or open circuit voltage (VOC) measurements of an optically switchable device of a window or door, which may include applying high voltage pulse(s) after detecting event where integrated VOC measurements taken after pulses indicate wire cut or breakage event. L'invention concerne des procédés et des systèmes pour détecter un événement sur la base de mesures de tension de circuit ouvert (VOC) et/ou de courant d'un dispositif optiquement commutable d'une fenêtre ou d'une porte, qui peuvent comprendre l'application d'une ou de plusieurs impulsions haute tension après la détection d'un événement où des mesures de VOC intégrées prises après des impulsions indiquent un événement de coupure de fil ou de rupture.
