The SIRCHIE® letterbomb detector is specifically designed to counter the increasing menace of terrorism for both corporate and government installations. Its unique design incorporates a freestanding structure comprised of a highly sensitive, self-tuning, balanced induction coil system spanning the entire width of the sloping letter chute. Factory alignment procedures ensure optimum performance at all times. Visual and audible alarm indicators provide attention-getting notice of metal detected. The LW101W is sensitive enough to detect the presence of a staple, ensuring rigid screening practices. Operation consists of allowing a suspect letter to slide across the surface chute. If metal is detected in the letter, a visual and audible alarm will be activated. The unit is fully automatic, requiring no operator adjustment and operates on 110 VAC, 220 VAC or its own internal battery source for stand-alone, field operation, switch selectable at base of unit.

The LW101W letterbomb detector screens oversize pouches.
