Mounting Considerations

The D7050‑B6 Base can be mounted on a four‑inch
square, a four‑inch octagonal, or a single‑gang box. It
can also be surface mounted with anchors, mollies, or
wing nuts.

Number of Devices Allowed on Loop

The number of multiplex smoke or smoke‑heat
detectors allowed on the multiplex bus is determined
by the wire gauge and the total wire length of the bus.
Do not exceed 30 Ω maximum line resistance. For
multiplex bus wiring requirements, see the D7039
Installation Guide.

Wiring Connection to D7024 MUX bus through D7039

Notice

Do not use shielded cable.

The D7050-B6 bases can be wired in a series or using
the T‑tap method. See the following illustrations.
