Setup Unit
Upon initial installation, the Setup Unit screen should be used to define installation
parameters specific to the job site.
The SRCM can take as input, the signal from two separate pressure transducers. These
are configured for either Primary Room or Secondary Room (an anteroom is an exam-
ple 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 momen-
tarily, cycling from one to the other a few seconds apart.
*If Ch1 is selected for the Primary room, it will not be an available option for the
Secondary 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 Analog Ch1. The FS output and range
of the external sensor will need to be entered.
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 Analog Ch1. The FS output and range of the external sen-
sor will need to be entered.
Use the radio button to select the setup parameters for either the Primary Room or
Secondary Room.
