WARNING

To reduce the risks associated with hazardous voltage:

•Do not use the product if the case, covers, or power cord are damaged.

•Do not attempt to modify, service, or repair—no user serviceable parts inside—contact 3M Service for repair.

Environmental requirements (operation)

Typical ambient temperature range: 32° F – 122° F [0° C – 50° C]

Humidity: 0% to 85% relative humidity, non-condensing

Environmental requirements (storage)

Typical ambient temperature range: –40° F – 131° F [–40° C – 55° C]

Humidity: 0% to 85% relative humidity, non-condensing

Detection zone

The primary zone of detection between two lattices extends 6 in. [15 cm] above the surface of the floor to 72 in. [1,82 m] above the floor. The electronic coverage in this zone is not 100%, but the rate of detection is effective to deter the loss of protected materials. It is important to watch for suspicious actions such as holding materials above or outside the lattices when passing through the system.

Indicators
