LifeSafety Power FPO75-C4D8E2 Power Supply Board, 75W

Designed for dependable door monitoring in commercial security and access-control systems, the Nascom N400B-STDD magnetic contact provides durable performance where false alarms are not an option. This surface-mount industrial bar contact uses hermetically sealed, double-pole double-throw (DPDT) contacts to offer flexible wiring and long operational life, while the extra-wide N35 NdFeB rare-earth magnet maintains a larger air gap to accommodate shifting or warped doors. Housed in rugged ABS with a center jacketed wire lead and a spacer for steel doors, the N400B-STDD installs quickly and resists environmental contamination. Rated to 300V DC with a low 0.2A draw and listed to UL634, it integrates cleanly into intrusion monitoring, access control, and surveillance systems where code-compliant reliability matters. Choose the Nascom magnetic contact when you need consistent, low-maintenance door protection across high-traffic commercial sites. Ideal for security integrators and facility managers — add the N400B-STDD to your next access control or alarm project.
