MCLASS Multi-purpose enclosures offer maximum flexibility, functionality and savings to access system designers. MCLASS Enclosures are engineered to house FlexPower power management boards alongside Mercury Security access panels in one compact, secure system. The E8M3 can be configured for a maximum of 16-doors plus I/O with dual voltage distribution. To prevent damage to system electronics, the backplates separate from the enclosure for access hardware mounting in the shop while wiring is pulled to the enclosure at the job site. Once configured, the backplates can be remounted for final ties and checkout.
