Pentatech Fd25

Whether you place it on a surface or hang it up, this affordable motion detector is highly effective. The built-in PIR sensor in the motion detector responds to movement and body heat, triggering a bright flashing light, siren sound, or one of 24 selectable melodies at the receiver unit. It is also possible to issue a warning using only an optical signal. Power can be supplied either by 2x AA batteries or an adapter. The FD25 can be used to monitor hallways and open doors, announce visitors or customers, and supervise rooms. Whether in a home, store, office, or hotel room, the motion detector is ready for immediate use. A practical all-rounder.
