Dwyer RSM - Manual

Bulletin P-3-RSM
The Series RSM Room Status Monitor is designed for critical low
differential pressure applications that require stringent pressure
monitoring and alarming. The Series RSM can be configured to monitor
positive or negative pressure in protected environments and hospital
isolation rooms per CDC guidelines. The RSM is a complete system that
includes a backlit RGB LCD display with a graphic user interface which
enables access to pressure, security, calibration, and alarm setup. The
touch-screen displays menus that guide the user through setup, as well
as setting up password protection. Red and green LED's and a local
audible alarm (with time delay feature) alert personnel to system status.
The RSM has a NEMA 1 (IP20) rated fire retardant plastic for indoor
applications. True differential pressure is displayed with a resolution of
0.001 in w.c. The very low pressure capacitance is dead ended and
avoids the potential for cross contamination of the room and reference
space as well as eliminating drift that results from fouling of flow based
sensors, which by nature have a flow path connecting the protected and
reference spaces. Additionally, there are two levels of password
protection available as well as optional BACnet MSTP communication.
1.0 INTRODUCTION
Congratulations, and thank you for purchasing Dwyer Instruments’
Room Status Monitor (Series RSM). Its ease of operation and durable
construction will provide years of reliable service. While the Series RSM
is easy to operate, it is advisable to read this guide carefully before use.
It is designed to help you take full advantage of the function and
performance of the Series RSM.
1.1 INTENDED USE
The Series RSM is designed to monitor critical air environments,
providing room static pressure indication, alarming, and communication
functions. The applications include:
1.
Hospitals - patient isolation and protection rooms, operating suites,
intensive care and emergency rooms.
2. Pharmaceutical, semiconductor, precision, manufacturing and clean
rooms.
3. Laboratories - medical research and BSLs (Bio-Safety Labs),
radiation, toxic metals and chemicals.
