Here are some photos of the Sequencer. For those that don't know already the Sequencer is an All On relay used in place of a timer in slave transformers that are linked to a master transformer via a wire housing a timing option such as an appliance timer, UPB, or X-10. You simply run a wire (any low voltage cable no smaller than 18/2)from the Master's 12v tap to the red and black knobs on the Sequencer housed in your 1st Slave unit. From that Slave you can pull from the 12v tap another wire to run to the next Slave's Sequencer repeating this step for as many transformers as you need. Once the Master's timer fires it will send a signal via the 12v tap to fire the Sequencers simultaneously. Contact me with any questions!!
