Description
2/1/2021 For customers who own our ALC technicians kit, we now offer a replacement for the now obsolete HAI Omni and OnQ HMS controllers. Call 864-663-0014
1/3/2021 Stewart Electronics announces ALC Test Kits and Remote Support – Call 864-664-0014
6/3/2019 Stewart Electronics announces that ALC Lighting products will no longer be manufactured!
We have a supply of Refurbised ALC Dimmers, Relays and Scene Switches.
2019 ALC was made obsolete by two factors. First, HAI Levition obsoleted their line of controls that were the major controller used with our ALC lighting.
Secondly we learned that the principle semiconductors used in the manufacturing of our light switches are now OBSOLETE!
For the same reasons we will no longer be able to make repairs to your circuit boards. We do sell refubished ALC switches while they last.
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.

Information below is for historical purposes only.
The ALC line of automated lighting products was previously owned by OnQ Legrand. Since 2009 Stewart Electronics has owned and manufactured this line of products in the USA.
If you have an ALC lighting system or if you are a contractor supporting this product line you NEED this tool kit! Connect it at the branch interface where all the communications cabling (the Polling Loop) begins and test all ALC products at the same time. Or, take it to the location of each wall switch and connect it to a single switch at a time (by un-wiring only the two wire polling loop).
Without this tool kit troubleshooting can takes countless hours of guess work!
*** THE 1 BRANCH TOOL KIT CAN TEST INSTALLS WITH 1 TO 31 ALC LIGHT SWITCHES, THE 4 BRANCH CAN TEST INSTALLS WITH UP TO 124 ALC LIGHT SWITCHES ***
Training is available On-Sight, Remotely or in our Automated Classroom in South Carolina.
THE NEED: Often we have customers return numerous ALC switches for repair. However, we typically only find ONE of their ALC switches to actually be bad. Sadly, ALC communications wiring (the polling loop) is often ran in a Daisy Chain fashion instead of a Home Run pattern. With daisy chain wiring, should one switch fail it can shut down communications with many if not all of the remaining ALC switches on that cable run.
The end result is that you must often un-wire each switch one at a time and ship them back for us to evaluate.
Our ALC Technician’s Tool Kit is simply the best tool to use to troubleshoot ALC lighting systems. Includes:
CAUTION: Connecting to an electrical circuit should be done by a licensed electrical contractor.
- ALC Circuit Tester
- Start with connecting all of the branch cables leaving the lighting controller and test the entire branch circuit all at once.
- Should numerous switches not show up on this test, move the tester to each wall switch and test each one by itself.
- This tester is portable so that you can take it to each wall switch.
- No more un-wiring each switch. Instead:
- Turn off the breaker, pull the switch out of the box just far enough to get to the ALC polling loop wire (2 conductors).
- Cut the ALC Polling loop loose (remember how to put it back later).
- Turn the AC breaker back on.
- Attach the tester to these wires and test just this one switch.
- If it fails, do not connect it back to the polling loop. Instead reconnect all polling loop wires and retest from the branch circuit.
- If there are still failures move the tester to the next wall switch and repeat the procedure.
- No more un-wiring each switch. Instead:
- ALC Diagnosis Software
- Some versions come pre-installed on Mini Windows PC.
- Identifies working and failed switches.
- Control each switch by turning on / off, bright / dim or flash on and off.
