Connections - you'll want one offered in each branch. Along with the offer side detector, NFPA 90A claims an in-duct smoke alarm is required on the RETURN side of any model greater than 15,000cfm. These detectors are expected at each history before the connection to a standard return and prior to any recirculation or outdoors inlet. They are not required where the whole space is protected by place smoke detection.
