What Is Unique About Meridian
?
Patented Flush Mount Room Sensors
Our flush mount room sensors are so unique, they are
patented (U.S. Patent No. 4,659,236). Even though part
of the sensor is recessed into the wall to provide an
attractive yet tamper proof flush mounting, internal wall
temperatures do not influence the sensor. A special plate
on the face of the sensor accurately senses space tem-
perature. Even though the attractive off white plastic
housing is a preferred color, the sensor housing can be
painted or wallpapered to blend with room decor with-
out affecting sensor performance. The sensors are of-
fered in four different configurations:
•
Sensor
•
Sensor w/override
•
Sensor w/setpoint adjustment
•
Sensor w/setpoint adjustment & override
Modular Connections
Many Meridian
auxiliary devices are connected to the
controllers via modular plugs like the ones used on tele-
phones. This simplifies installation and eliminates the
possibility of wiring errors. The devices, which utilize
this method, are damper actuators for zone and bypass
control, auxiliary relay boards, and static pressure/air
flow sensors. There is one interesting side note about
the auxiliary relay board and airflow sensors. These
devices are typically used on the zone controllers in the
Meridian
Basic & Plus systems. When the system is
powered up, it automatically looks to see if these de-
vices are connected to the controller. If they are, the
controller automatically reconfigures itself to utilize
these devices and activates the appropriate set up screens
back at the operators interface. Pretty neat don’t you
think!
FREE! Windows™ Graphics Software
Each Meridian
system can be monitored on site or re-
motely using a PC and our Prism
computer front end
software software. This full-featured package is very
user friendly and can be used to monitor one system or
hundreds. The Prism
software is not copy protected
so it can be installed on multiple PC’s’ without addi-
tional expense. Just some of its many features include
but are not limited to:
•
Pre-designed status screens for all controllers
•
Alarm dial out capability
•
Programming of all system parameters
•
Trend logging to Excel™ spreadsheets
•
Alarm Handling
•
Custom graphics capability
Open Protocol System
Meridian
is an open protocol based system allowing
other manufacturers to develop direct interfaces to the
communications loop. This gives you the ability to in-
tegrate the Meridian
system into products from other
vendors. Our engineering staff will be glad to assist any
vendor in this process.
