Form 2 Siemens BMS panels for a hospital refurbishment
A BMS integrator was replacing the building controls in a hospital refurbishment. We designed and manufactured the two BMS panels for the plant room: Siemens PXC7 controllers, Form 2 segregated, with surge protection and full manual control from the door.
- Site
- Hospital refurbishment
- Panels
- 2, Form 2, one a two-enclosure suite
- Controls
- Siemens PXC7 with TX-I/O
- Largest
- 1800x1200 + 1800x600mm
The challenge
BMS panels for a hospital refurbishment, controlling air handling units, pumps and smoke and fire damper interfaces across the plant.
What we supplied
Two Form 2 BMS panels on Siemens PXC7 controllers, the larger a two-enclosure floor-standing suite with 21 TX-I/O modules.
The result
Every item of plant on the door with hand/off/auto, enable, run and fault, and every signal on a labelled terminal.
The requirement
Two BMS panels for the refurbished plant, both Form 2 segregated, with type 2+3 surge protection and Schneider MCBs as specified. The larger is a floor-standing suite of two enclosures, 1800x1200mm double-door and 1800x600mm, with a Siemens PXC7 controller and 21 TX-I/O modules. The second is a 1000x1200mm double-door panel with a PXC7 and 10 modules.
The constraints
- A live hospital, so the panels had to be right on arrival and fully documented for the estates team.
- Manual control from the door for the air handling unit supply and extract fans and the run-around coil and LTHW pumps.
- Frost, filter and smoke detection, plus interfaces to the fire alarm and the smoke and fire damper panel.
- Form 2 segregation, surge protection and a specified make of MCB.
What we built
Both panels drawn from the integrator's points schedules and built on our standard BMS platform: the PXC7 and its TX-I/O modules, interposing relays for every enable, towers of labelled terminals for the field wiring, and an engraved door fascia giving hand/off/auto, enable, run and fault for each item of plant. Each was routine tested in Stoke-on-Trent and despatched with its wiring diagram and test certificate.
Delivery
Built and despatched one panel at a time over the summer of 2026.
The outcome
The estates team can see and run every fan and pump from the door without a laptop, and every field signal lands on a labelled terminal that matches the drawings. We can't name the hospital or the integrator; the photographs are of the panels themselves.

“Normally we'd expect a 6 to 8 week lead time on a panel build. In this case it was done in 12 working days, which is a testament to G&G Controls and SSE working together.”
- Wiring diagram, test certificate and 12-month warranty with every panel
- Built to BS EN 61439 and BS EN 60204-1 in Stoke-on-Trent
- We reply during working hours, usually the same working day

SSE Energy Solutions
A Form 2 outdoor BMS panel on the roof in 12 working days
SSE Energy Solutions were refitting the third floor of Highgate Mental Health Hospital in London: new walls, heating, HVAC, electrical and controls throughout, with a new BMS tying into the trust's existing Trend network. The panel for it had to sit on the roof, and the only crane was coming down in three weeks.
