The Savant® Keypad Link (SKL-4000) Quick Reference Guide provides the information necessary to install the SKL-4000. Each SKL-4000 connects up to 40 Savant keypads to any Savant SmartLighting controller with available RS-422 ports. Do not put more than 20 stations on a single homerun. Several homeruns are preferable to one long homerun and can easily be tied together at the controller. A total of 256 keypads may be connected to a Savant SmartLighting controller through multiple SKL-4000s. Double ganged keypads are considered two keypads.

Wiring the Savant Keypads to the Savant Keypad LinkTo connect the keypads to the SKL-4000, the wires from the 3-pin connectors must be spliced with the 3-wire cable running to the keypad backboxes. The next figure shows the use of 16-gauge (AWG) wire, but in shorter installations (up to 330 feet) 18-gauge wire can be used. Crimp connectors or wire nuts can be used to terminate the stranded wire. Crimp connectors are preferred.

Keypad Backbox
Note: Voltage readings at the end closest to the 3-pin connector should typically read no more than 1 or 2 volts less than at the Savant Keypad Link end.
Keypad backboxes should have a minimum inside dimension of 3 in. high x 1⅞ in. wide x 1½ in deep. Use a square-cornered backbox to best accommodate these dimensions. Do not use plastic rings with rounded corners—keypads, especially multiple-gang keypads, will not fit. Single-gang, metal cut-in boxes, plaster, or tile rings are not acceptable.
In new construction installations, for example, a single gang backbox, model P-241 (supplied by Allied Moulded Products) would accommodate a Savant keypad. An example of a double gang backbox is model P-442 (supplied by Allied Moulded Products).
Whether installing backboxes in new construction or “old work” installations, the installer should test fit the keypad to the backbox before installing the backbox in a wall.
Note: Keypads may be wired to a homerun device, not to exceed 1000 feet with 16 AWG or 330 feet with 18 AWG.
SKL-4000 Mounting InstallationTo recess- mount:1. Mount SKL-4000 to wall studs using screw holes located on the side panels of the
enclosure.2. Leave 3 inches minimum space between each SKL-4000 to accommodate the lids .3. Install all SKL-4000s before connecting the power.
To surface mount:1. Mount SKL-4000 to wall using screw holes located on the back panel of the enclosure.2. Install all SKL-4000s before connecting the power.
