cable must be used for the cable between poles. Note that this is not applicable to the PDU (which
does not have any detector inputs).
For further information including mounting arrangements, please refer to the Heimdall Handbook
(667/HB/31900/000).
4.7.1
Adding Above Ground Detectors to Poles without Signal Heads
If there is no head to connect the above ground detector, the AGD is to be connected to a RAG
Node on a near-by pole.
Alternatively, if there is a Plus+ Near-Side or PDU/Wait on the same Pole as the AGD, these must
be connected to the same Plus+ Cable as the RAG Node, i.e. be on the same Arm/Ring. (This
ensures that the power consumption of the AGD is considered by the Design Tool)
Note that every AGD on a Pole without any Plus+ equipment will not be included in the power
consumption calculations (on the assumption the Plus+ Cable naturally omits that Pole), so the
installer will need to check there is spare capacity on the cable powering the adjacent RAG Node.
