Does your dawn/dusk sensor have an over-ride facility on it so you can switch it on?
If not easiest thing replace it with a normal switch so you can switch it on/off when you like.
In commercial applications, we fit an MK two position rocker. (m/clad grid)
Centre is off completely.
Top is AUTO (switched by cell).
Bottom is override, switching the load on.
Typically used in commercial applications. The switch is usually placed out of site somewhere, such as a plant room (usually next to associated contactor if there is one). The switch is used by maintenance staff for re-lamping etc.
As for a diagram.......no, I don't have one, but may make one when time permits.
do you really need a diagram?! just get a center off rocker (e.g. http://www.tlc-direct.co.uk/Products/MKK4899.html , unfortunately MK only do it as a grid module so you will need the other associated grid bits), the live from the photocell to L1 and a permanent live to L2 and connect COM to the live side of the light.
