parameters specific to the job site.
The SRCM can take as input, the signal from two separate pressure transducers as well
as temperature, humidity, and user defined (ex. CO 2 ) inputs for up to two rooms. These
are configured for either Primary Room or Secondary Room (an anteroom is an example
of a secondary room). When two transducers are used, the Home screen display of the
SRCM can toggle between each space to indicate the status of each room momentarily,
cycling from one to the other a few seconds apart or the display can be locked on either
of the two rooms.
*If Ch1 is selected for the Primary room, it will not be an available option for the Sec-
ondary room.
Use the radio button to select the setup parameters for either the Primary Room or Sec-
ondary Room.
Change, if necessary, to match sensor being used. OnBoard is the default, which uses
the sensor manufactured on-board the unit. Alternatively, an external sensor (also
known as “external transducer” such as a Setra 264 or Setra 267) may be used. If an
external sensor is used, change this selection to ADC Ch1 (Analog Input 1) or ADC
Ch-2 (Analog Input 2). The FS output and range of the external sensor will need to
be entered. If the OnBoard Sensor is selected, a box is shown displaying the pressure
range and engineering unit.
Change, if necessary, to match sensor being used, if there is one present. None is the
default. An external sensor (also known as “external transducer” such as a Setra 264
or Setra 267) may be used for the secondary room, or anteroom. If an external sensor
is used, change this selection to ADC Ch1 or ADC Ch2, which use Analog Input 1 or
Analog Input 2, respectively. The FS output and range of the external sensor will need
to be entered.
