Master Remote Signal (Dry Contacts)
Emergency instructions may also be input (by the user) for each
of the signal points. The normal display will appear and react
just like a conventional remote signal master dry contact display
(shown on the left side of this page), but a touch of the display
will change the display (for 30 seconds) to look and react similar to
an area alarm gas display (photo at right). The advantages of using
transducers over pressure switches are;
•
Digital display of actual gas pressure
•
Greater accuracy / repeatability
•
Improved safety (an alarm condition notification is created
immediately should a transducer fail)
•
Easy / fast push button re-setting of alarm set points
•
Lower cost (in most cases)
Master 4-20 mA Remote Signal
Monitors the status of a source of the medical gas distribution
system (i.e. – liquid level of bulk oxygen) in communication with
one 4 – 20 mA signal input generate and display a bar graph with
user defined units, provide high & low alarms with user defined
set-points and provide the emergency instructions (programmed
by the user). Other applications may include monitoring flow rates,
levels, concentrations, humidity, etc.
Master (dry contact) modules will provide up to 8 alarm signals
when used in communication with dry contact sensors. For each
signal point a ‘label’ must be selected from a pre-loaded database
of NFPA 99 master alarm signals. You also have the option of
creating your own ‘label’. Emergency instructions may also be input
(by the user) for each of the signal points. The master boards are
pre-programmed with all signal points programmed NC (normally
closed). There is an alarm condition indicator for each signal point.
The alarm condition indicator will be green when the signal is in
a normal state and red when in an alarm state. When an alarm
condition occurs in addition to the condition indicator turning red,
the signal will flash on and off and the emergency instructions will
alternate being displayed with the alarm signal label.
Master Remote SIgnal (Transducer Contacts)
Master (transducer contact) modules will provide up to 8 alarm
signals when used in conjunction with Powerex transducer sensors.
For each signal point a ‘label’ must be selected from a pre-loaded
database of NFPA 99 master alarm signals. You also have the option
of creating your own ‘label’.
