Many people like to have signaling of one kind or another, especially on hidden reverse sections so they know whether or not it is being used.

With all other reverse section controllers, power is pulled from the track power bus. Even the Digitrax PM42 that has its own external power source draws some power from the track. This means that none of those reverse section controllers can be used downstream from a block detector. If wired downstream, between the block detector and track, the block detector will see the power being drawn by other reverse section controllers and falsely report a loco as being present. But since the ARSC draws no power from the track unless a loco is present, it can be safely used with block detection.

With an HGE block detector, since the reverse section is already isolated from the rest of the layout, simply place the HGE in one of the power lines to the ARSC, as shown below.

This illustration shows an HGE powering the track before and after the reverse section as well as the reverse section - making them all in the same detection block.
Wiring an ARSC with an inductive type block detector is exactly the same. Wiring the ARSC with a BDL16 is also the same.
NOTE: use of one ARSC for multiple reverse sections becomes exceedingly difficult with signaling, unless the reverse sections are excluded from detection blocks.
