Jablotron SA-220 roller door magnetic contact with floor contact

 

The garage door contact for heavy doors is a magnetic contact that secures larger doors (e.g. garages). Unauthorized opening is detected and reported to the alarm center. The garage door contact for heavy doors is mainly installed on rolling, sliding and tilting doors. The detector consists of a magnetic contact (reed) and a magnet. These are applied parallel to each other. The circuit of an NC opening detector is closed in the rest state. When the distance between reed and magnet increases, the current circuit is interrupted and an alarm signal is given. The detector is protected against tampering. The optimal location for installation is in the center of the driveway. The reed contact is mounted on the ground, the magnet - at a distance of approx. 20 mm - on the inside of the door. The garage door contact for heavy doors is very suitable for surface mounting. It is absolutely waterproof and dustproof (IP 68). Thanks to the extremely robust housing, the detector is resistant to damage from being run over.
