Generator source alarm panels for a standby-power dealer
Standby power generation (generator dealer and installer). Scope: panel design to project specification, submittal drawings, UL 508A shop build, repeat small-batch panels.
The challenge
A generator dealer installs standby gensets in public buildings and campuses. Those installations call for a remote generator source alarm panel, which annunciates the state of each generator circuit breaker and automatic transfer switch at a remote location.
Every job differs in several ways:
- the number of breakers and transfer switches;
- the control voltage (12 VDC or 24 VDC);
- the label text set by the project's electrical drawings.
Each panel also needs a submittal drawing that the dealer can send for approval before building.
What we did
- Designed each panel to the job. We worked from the dealer's markups and the project specification. Each design has a set of indicator lights per breaker or transfer switch, an audible alarm with a pushbutton, and front-panel legends with the breaker designations and ratings.
- Matched the front panel to the wiring. We arranged the light order left to right to match the terminal and schematic order top to bottom, so field wiring and troubleshooting stay straightforward.
- Supplied submittal drawings for approval before release to the shop. We swapped components where a job's control voltage changed (for example, 12 VDC indicators on a 12 V genset).
- Built the latest pair in our UL 508A shop. These were two 24 V, three-position circuit-breaker alarm panels in compact 12 × 12 enclosures, ordered in 2025 and picked up by the dealer when complete. Before release, our AutoCAD designer reworked the drawings to carry more detail, so the dealer had a fuller document set for its records.
- Added a field termination panel in 2026:
- an aluminum NEMA 4X enclosure, 12 × 10 × 5;
- 20 DIN-rail terminal block connections rated to 20 A;
- the enclosure layout drawn by our project engineer.
The result
The dealer has come back job after job since 2019 for source alarm panels sized to each installation, and it added the termination panel in 2026.
What it shows: fast-turn custom panels built to specification, submittal-quality drawings, DC control and annunciation design, and a long-running relationship with a power-generation partner.
