LifeSafety Power E8M-BOXED provides the enclosure platform for access-control installations that combine LifeSafety Power power-management hardware with Mercury Security panels. Its removable backplate lets access hardware be mounted away from the cabinet while field wiring is pulled to the installation location, then remounted for final termination and checkout. The E8M platform supports configurations for as many as 12 doors with dual-voltage distribution. A protected AC input terminal, AC on/off circuit-breaker switch, pre-engineered access mounting pattern, threaded standoffs, and multiple knockouts support cabinet integration. The 6.5 in enclosure depth accommodates 12 Ah battery sizes.
