A system which indicates when a blown fibre unit 6 has reached its required final destination via an audible and visual signal. A radio signal is sent from an end sender 1, once a micro switch 2 at the final destination has been touched by a fibre unit 6, to a portable receiver 3. Both the end sender 1 and the receiver 3 give audio and visual signals. This allows a user of a fibre blowing machine to differentiate between a fibre unit 6 being stuck 7 in a conduit and one which has reached its required final destination. |
