The E8MH access enclosure is engineered to house either Mercury Secu- rity® or Honeywell Pro-Watch® access panels on a removable backplate. The E8MH can be configured for a maximum of nine panels / eighteen doors and has no mounting provisions for power. To prevent damage to system electronics, the backplate separates from the enclosure for access hardware mounting in the shop while wiring is pulled to the enclosure at the job site. Once configured, the backplate can be remounted for final ties and checkout.
