The iWISE® QUADSEQ G3 contains two independent detectors in a single housing. When mounted in the corner of a room, one detector covers the two walls (side area), while the second detector covers the center of the room.
When an intruder enters the room via a door or window, the side area triggers. When the intruder then moves to the center of the room, the second detector triggers, providing a sequentially confirmed alarm according to UK APCO: DD243 requirements.
