A builder running an Austin new-construction or renovation project usually has three different trades touching the same wall cavity: the technology integrator, the licensed electrician, and the alarm contractor. They are not interchangeable, and confusion over who pulls which wire — and who is actually allowed to connect it — is a common cause of a stalled rough-in. Ask each firm you hire which license covers their portion of the wall before walls close; it is a cheaper question to ask at the design stage than after drywall.
Where the low-voltage line actually sits
Motorized shade wiring is a good illustration of where a low-voltage run ends and electrical work begins. Crestron's own installation documentation for its QMT shade motors describes "-EX" motors that require only a power connection and "-CN" motors that need both data and power, and states that shades should be "home run from the power supply" — a dedicated power supply unit (such as the CSA-PWS40 or CSA-PWS10S-HUB-ENET) that feeds the motors over low-voltage wiring (Motor Wiring). That power supply unit itself still needs a feed from somewhere, and whether that feed is treated as electrical work on your project is a question worth confirming directly with your electrician and your jurisdiction, not assumed from the product documentation alone.
The trade press describes a similar boundary more broadly: switches and panelized dimming modules "need to be installed by a licensed electrician," even on jobs where an integrator specifies and procures the fixtures and the control logic, and even outdoor landscape lighting — "technically low-voltage for the most part" — still needs someone to install the power supplies that feed the fixtures (Should You Become an Electrician?). In practice, this means an Austin drawing set should mark every shade power supply, every dimmer, and every landscape lighting transformer as a candidate handoff point between the integrator's low-voltage run and whatever higher-voltage circuit feeds it — and that handoff should be confirmed with the electrician of record before the rough-in walkthrough, not during it.
Why monitored alarm work is treated as its own scope
Monitored alarm installation tends to run through a different contractor relationship than general low-voltage work, and it is worth asking your alarm provider directly what licensing applies in Texas before assuming your integrator or electrician can take it on. Alarm.com's own description of how its systems reach a home is instructive on why the separation exists operationally: the company states that its technology "is sold, installed and serviced by licensed service providers" who are "trained to install Alarm.com systems, set up your devices, activate your app, and keep your system running long term," with an emergency signal "instantly sent to a Central Monitoring Station" that the security dealer manages (How to Get and Install Alarm.com). That central-station relationship, and the dealer relationship behind it, is a distinct scope of work from a low-voltage installer pulling cable for a network switch or a lighting keypad — ask your prospective alarm provider which license or registration covers their installation and monitoring work in your jurisdiction.
For a builder, the practical consequence is that an Austin project's drawings should identify monitored alarm devices — door and window contacts, motion sensors, the alarm panel location — separately from the integrator's AV, network, and lighting-control devices, because a different contractor is likely to install and commission them even when the wiring runs through the same conduit path.
What belongs on the drawing set for each trade
Given that split, the integrator's drawing set has to speak three different languages:
- For the electrician: a power and load schedule that marks every shade power supply, every dimmer location, and every panel feed the lighting-control system depends on, with voltage and circuit requirements called out before the panel schedule is finalized.
- For the alarm contractor: device and riser locations for contacts, sensors, and the panel itself, plus conduit stub-outs sized and routed before drywall, so the alarm installer isn't fishing wire through finished walls.
- For the integrator's own crew: Cresnet and shade-motor home runs back to the power supply, network cable runs, and the AV and control wiring that falls inside their own scope.
Sequencing rough-in across three trades works best when all three sets of locations are on the same drawing, reviewed together, before the electrician's rough-in and the integrator's pre-wire happen in the same walls during the same week. Commissioning tends to follow the same order in reverse: the electrician energizes the circuits, the alarm contractor tests and registers the panel with the central station, and the integrator commissions control, shading, and network devices against power that is already live. Confirm this sequence and its dependencies with your general contractor early, since every build schedules it a little differently.
Cave Group plans Austin projects with this split in mind, working designs out from New York and coordinating with Texas-licensed trades on site.
