Lobby Enclosures
The paging and telephone control modules fit into the Mircom BB-1000 series lobby enclosures, except the QMP-
5101B and the QMT-5302, which mount only into a BB-5008 and BB-5014. All selector panels mount into all the
BB-1000 series and the BB-5008 and BB-5014 enclosures. These semi-flush backboxes include the BB-1001
(houses only one module), the BB-1002 (houses two modules), and the BB-1003 (houses three modules).

Note: It is extremely important that you connect one of each BB-1000 series backbox
earth-ground points (chassis ground) to earth ground (cold water pipe).
