Jablotron SA-220 roller door magnetic contact with floor contact
Jablotron SA-220 roller door magnetic contact with floor contact.
Wired magnetic contact specially designed for roller doors, garage doors etc.
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 primarily installed on roller, sliding and up-and-over doors. The detector consists of a magnetic contact (reed) and a magnet. These are applied in parallel to each other. The power circuit of an NC opening detector is closed at rest. When the distance between reed and magnet increases, the power circuit is interrupted and an alarm signal is given. The detector is protected against tampering. Optimal location for mounting is in the middle 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 well suited for surface mounting. It is absolutely water- and dustproof (IP 68). Thanks to the extremely robust housing, the detector is resistant to damage caused by running over.
