November 21, 201213 yr Can you suggest a package to provide 3 x independently switchable on/off beams of 12m, 9m, 6m span with a control panel and sounder. The sounder to mute after a preset time. the system to be mains/ 12v powered. The detectors to be preferably powered from one end only of each beam. As cheap as possible, p.s. external use near the ocean.
December 11, 201213 yr I wouldnt recommend this as id use a galaxy or a HKC for flexability but Use an optima or accenta with the bell time at 1min Connect the active beams (standard beams will require cabling to both sides) and use shunt switches in parralel with the circuit to shunt.
