Controls Direct supplies Setra and Dwyer room monitoring products for Australian healthcare, laboratory, cleanroom and pharmacy projects. This guide outlines the documented technical features of Setra SRCM, Setra FLEX, Dwyer RSMC and Dwyer RSME, with practical information for consultants, mechanical contractors and BMS integrators.
Equipment selection starts with the room schedule, required measurements, alarm philosophy and BMS specification. Confirm the full part number, sensor arrangement and installation requirements for the product being supplied.
Setra SRCM room condition monitor
SRCM provides local pressure and environmental indication with configurable audible and visual alarms. Its touchscreen can present information for a primary and secondary room, using the required measurement sources.
| Item | Documented specification |
|---|---|
| Room capacity | Up to two rooms |
| Displayed parameters | Up to four per room |
| Display | 4.3-inch colour touchscreen |
| Network communication | BACnet MS/TP with the appropriate configuration |
| Inputs | Two analogue inputs and a dedicated door-status input |
| Analogue output | Primary-room differential pressure |
Allocate external pressure, temperature and humidity signals before ordering. Display capacity does not represent the number of dedicated physical sensor inputs. Confirm the BACnet option and review the object list with the BMS contractor.

Setra FLEX room environmental monitor
FLEX presents multiple environmental measurements on a local touchscreen and supports integration with networked building systems. The software configuration determines the monitoring and control functions provided.
| Item | Documented specification |
|---|---|
| Room capacity | Up to three rooms |
| Displayed parameters | Up to six per room |
| Display | 7-inch colour touchscreen |
| Network communication | BACnet/IP and BACnet MS/TP |
| Pressure sensing | On-board or external sensor configurations |
| Software options | FLEX-RM for monitoring; FLEX-RC adds PI-loop or network control |
Specify the required sensors or supported network sources for each displayed value. Where control is required, document the equipment, input/output allocation and approved control sequence for the selected FLEX-RC configuration.

Dwyer RSMC critical room status monitor
The Dwyer RSMC StabiliSENSE critical room status monitor provides touchscreen indication and alarms for low differential-pressure applications. Its documented applications include hospital isolation rooms, laboratories and pharmaceutical facilities.
| Item | Documented specification |
|---|---|
| Room capacity | Up to three rooms |
| Displayed parameters | Up to four parameters, as described in the manufacturer’s data sheet |
| Display | 4.3-inch colour touchscreen |
| Network communication | BACnet MS/TP and Modbus RTU |
| Inputs | Two selectable 4–20 mA, 0–5 VDC or 0–10 VDC inputs; one door-status input |
| Outputs | One digital output and one selectable 4–20 mA or 0–10 V output |
| Power | 24 VAC/VDC |
Confirm the pressure range, accuracy option, bezel and sensor allocation for the ordered model. Review how parameters will be allocated across the intended rooms, together with the BMS points and alarm requirements.
Ask Controls Direct for Dwyer RSMC model selection, accessories and availability. View the Dwyer RSMC manufacturer data sheet.
Dwyer RSME room status monitor
The Dwyer RSME monitors low differential pressure in positive- or negative-pressure rooms and provides local visual and audible alarms. Documented applications include hospital isolation rooms, laboratories, cleanrooms and pharmaceutical facilities. For Australian healthcare, pharmacy and laboratory projects, confirm the required pressure range, alarm settings and sensor arrangement against the approved room schedule.
| Item | Documented specification |
|---|---|
| Room capacity | Up to three rooms with the required measurement sources |
| Displayed parameters | Up to four parameters, including pressure, relative humidity, temperature, air change and/or door status |
| Display and alarms | 4.3-inch colour touchscreen; green, yellow and red status indication; audible alarm |
| Pressure sensing | Piezoresistive pressure sensor for air |
| Network communication | BACnet MS/TP and Modbus RTU as standard |
| Inputs | Two user-selectable 4–20 mA, 0–5 VDC or 0–10 VDC inputs; one digital door-status input |
| Outputs | One digital output rated 5 A at 30 VDC; one selectable 4–20 mA or 0–10 V output for internal pressure or retransmission of an input |
| Power | 24 VAC/VDC |
| Installation and options | 27.5 mm mounting depth; optional brushed stainless steel bezel; optional NIST-traceable calibration certificate |
RSME pressure ranges and accuracy options
The model chart lists unidirectional ranges of 0–0.5, 0–1 and 0–2 in w.c., and bidirectional ranges of −0.5 to +0.5, −1 to +1 and −2 to +2 in w.c. The display supports Pa, kPa, cm w.c., mm w.c. and in w.c. Provide your design range in Pa so Controls Direct can confirm the appropriate ordering code.
RSME-B models have a stated ±0.5% RSS accuracy and RSME-C models ±1% RSS, after a one-hour warm-up period. Review the manufacturer’s accuracy definition and operating conditions for the exact model. The stainless steel bezel uses the -SS suffix; the optional calibration certificate uses -NIST.
RSME sensors and BMS integration
Allocate the external sensor signals and door contact before ordering. The number of displayed parameters does not mean that all measurements are sensed inside the monitor. Temperature, humidity, additional room pressures and airflow-related information require the appropriate measurement sources. For BMS contractors, confirm the selected protocol, communication settings, point mapping, input scaling, alarm response and commissioning requirements. A differential-pressure reading alone does not establish air changes per hour.
Browse Dwyer RSME models at Controls Direct, including RSME-B-014 and RSME-C-014. Ask Controls Direct to confirm the model, pressure pickups, tubing, external sensors, mounting accessories and availability for your project.

Planning a complete room monitoring system
- Healthcare and isolation rooms: identify the approved room and reference-space relationships, door response, local alarms and staff-station indication.
- Operating theatres: coordinate pressure, temperature, humidity and any airflow or ACH readings with the mechanical design.
- Laboratories, cleanrooms and pharmacies: map the containment boundaries or pressure cascade and define the required environmental records.
- BMS integration: confirm the specified protocol, point mapping, input scaling, alarm priorities, trends and communication-failure response.
Information to include with your enquiry
Provide the room schedule, drawings, pressure range in Pa, required measurements, BMS interface, alarm requirements, quantities and delivery date. Include pressure pickups, tubing, external sensors, power and mounting accessories in the equipment schedule. For existing installations, provide the model and wiring details so the complete arrangement can be reviewed.
Frequently asked questions
Are all displayed measurements sensed inside the monitor?
No. Additional room and environmental readings require the appropriate external sensors or supported network values. Confirm each signal source in the quotation.
Does room pressure establish air changes per hour?
No. ACH requires the relevant airflow information and room-volume basis. A pressure reading alone does not establish the ventilation rate.
Does a monitor certify room compliance?
No. Suitability depends on the complete facility design, approved specification, installation, commissioning and operating procedures.
Australian selection and project support
Controls Direct assists Australian consultants, mechanical contractors, BMS integrators and facility teams with product selection. Send your room schedule, required pressure range in Pa, alarm requirements, BMS specification, sensor list, quantities and required delivery date. For replacements, include the existing model, wiring details and wall opening dimensions. Request confirmation of the exact configuration, accessories and availability before ordering.
