System configurations
The 3M Detection System Model 3900 series consists of four models: 3901, 3902, 3911, and 3912. The following illustrations
show the buried cable mounting option. Other mounting options include direct mounting with the connecting cables routed
under either a narrow threshold or a wide baseplate. All models function identically; the only difference between Models

Models 3901 and 3902
Models 3901 and 3902 have solid panels on the lattices. Model 3901 has a single corridor, whereas Model 3902 has two
