6/3/2019  Stewart Electronics announces that ALC Lighting products will no longer be manufactured!

 WE DO HAVE STOCK ON MOST ALC PARTS! At least for now! Original prices are greatly reduced (while they last). Quantity limits apply.

We recently learned that the principle semiconductors used in the manufacturing of our light switches are now OBSOLETE!

We advise those of you with ALC products installed in your homes to contact us to purchase some spares. Our light switches had less than a .01 percent failure rate. So, a few spares may last you for many years.

For the same reasons we will no longer be able to make repairs to your circuit boards.

CONSIDERING UPGRADING? For the past 25 years we have consulted on installs across North America. Our initial advice is free. Call us to discuss your home’s future.

We also have a decent stock of the recently obsolete HAI Omni controllers.

Information below is for historical purposes only.

The part no. 364678-01 ALC Input/Output (I/O) Module (see Figure 1) provides programmable, general purpose input and output control features. The ALC I/O Module may be installed and operated in any On-Q Home Lighting Controller or Scene Learning Interface system. Each ALC I/O Module communicates with the controller via the ALC communications branch. The I/O Module includes two programmable inputs that may be programmed to control any ALC Dimmers, Relay Switches or I/O Module outputs. The I/O Module also includes two programmable outputs that may be controlled by any ALC Scene Switch button, Program Switch button or I/O Module input


Each of the programmable inputs may be configured to sense and activate on application of a contact closure (Normally Open) or a voltage; 5 to 24 V AC/DC. Conversely, each of the programmable inputs may be configured to sense and activate upon the removal of a contact closure (Normally Closed) or a voltage.

The user may configure the programmable relay outputs for application of either of two voltage sources (up to 24V AC/DC) or contact closure to each output relay’s terminals. Each output relay terminal block provides the user with the flexibility to choose either “Normally Open” or “Normally Closed” operation. Each output relay provides current capacity to source up to 2A to an external device.
