Keypad Control

A fully programmable keypad that's capable of switching any load or groups of loads anywhere on the system.

A strategically located keypad can replace dozens of switches, and better still, you have control of any load in the system by simply inputting the strategy into the computer. The keypad itself is 5 1/2" wide by 5" high with a total of 16 keys. To control a load, four digits are required, plus an ON or OFF command. The keypads reside on a four wire bus connected to the control computer. Up to 10,000 individual codes are available.
