Series RSMC StabiliSENSE
Specifications - Installation and Operating Instructions
RSMC with standard plastic bezel
The Series RSMC StabiliSENSE™ Critical Room Status Monitor is designed for
critical low differential pressure applications that require stringent pressure monitoring
and alarming. It can be configured to monitor positive or negative pressure in clean
rooms, hospital isolation rooms, school nurses offices, laboratories, and vivariums.
The RSMC is a complete system with a touchscreen graphical user interface which
enables access to pressure, humidity, temperature, air change, security, door status,
calibration, and alarm setup. The graphical display color changes allow a clear
determination of when the parameters are operating within the acceptable range
(green), caution range (yellow), or have gone outside the acceptable operating range
(red). The RSMC StabiliSENSE™ critical room status monitor comes standard with
BACnet MS/TP and Modbus RTU communications.

1.0 INTRODUCTION

The Dwyer Series RSMC monitors room parameters in a variety of applications. Its
®
ease of installation and intuitive setup, provides a great user experience. While the
RSMC is easy to operate, it is advisable to read this manual carefully before use. It is
designed to allow the user to take full advantage of the function and performance of
the Series RSMC.

1.1 INTENDED USE

The Series RSMC is designed to monitor critical air environments, provide room
pressure indication and 3 additional user-defined parameters user-selectable as
temperature, relative humidity, air change per hour (ACH), door status, and/or additional
pressure measurements. The RSMC Series has alarming and data communication
over Modbus RTU or BACnet MS/TP. The applications of the RSMC include:
®
1. Hospitals - patient isolation and protection rooms, operating suites, intensive
care, and emergency rooms.
2. Precision manufacturing - pharmaceutical, semiconductor, and clean rooms.
3. Laboratories - medical research, bio-safety labs (BSLs), and vivariums.

1.2 RSMC FUNCTION

The Series RSMC senses low differential pressure using a capacitive cell pressure
sensor. The RSMC senses the differential pressure between a protected environment,
such as a clean room or isolation room, and an area outside the room. Maintaining
a constant differential pressure between the two spaces is critical in ensuring the
room is protected by ingress for the outer room or vice-versa. The RSMC can be
programmed to monitor either positive or negative room static pressure in 1 to 3
locations. In total, it can monitor up to 4 parameters: built-in differential pressure, up
to 2 additional differential pressures as inputs, relative humidity input, air change per
hour (ACH) input, and door status. The touchscreen user interface allows for easy
setup of the multi-parameter alarming and 2 levels of security protection. The BACnet
communications allows the device to communicate with other BACnet devices, such
as sensors, and allows the supervisory system to change configuration setups and
monitor alarm conditions.
