The Orno 708 is a magnetic contact alarm set that sounds an audible alert whenever the two device elements are separated — deterring intruders and simultaneously notifying occupants of unauthorised entry. It requires no wiring, running entirely on batteries.

Suitable for doors, windows, and any movable access point, the 708 can also be used in automatic control systems to monitor access to specific spaces or facilities.
