Optional features include a resistive temperature sensor output (with LCD display of temperature in either
°C or °F), a control relay with programmable setpoint, hysteresis and time delay, an up/down setpoint
control with various resistive output ranges and a dry-contact override switch.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the device. Failure to follow these
instructions may result in product damage. Do not use in an explosive or hazardous environment, with
failure of the product could result in personal injury. Take electrostatic discharge precautions during
installation. De-energize the power supply prior to installation, this device is intended for indoor air
conditioned spaces, contact factory or other applications. Do not exceed device ratings. This product is
not intended for life-safety applications.
NOTE:
This CO
sensor incorporates a Self Calibration feature to
2
correct CO
sensor drift. This feature is recommended for applications
2
where the CO
will be exposed to fresh air (400 ppm) at least one hour
2
per day. If the monitored space is occupied 24 hours or consistently
maintains higher or lower levels of CO
calibration is disabled at installation time without allowing for 7 day
auto calibration cycle, then a manual calibration should be performed
to ensure accuracy of the device.
MOUNTING
The transmitter installs directly on a standard electrical box and
controlled. Do not mount the sensor near doors, opening windows,
the detector is exposed to vibrations or rapid temperature changes.
Prevent measurement errors by sealing the wall or conduit openings
to prevent air migration from the wall cavity.
The cover is hooked to the base at the top edge and must be removed
the security screw as shown in Figure 1. Complete removal of the
screw is not required. Use the screwdriver to carefully pry each bottom
corner if necessary. Tip the cover away from the base and sit it aside as
shown in Figure 2.

INTRODUCTION
The room CO
transmitter device uses a highly accurate and reliable non-

room applications to monitor CO
and LTA (long term adjustment) signal processing technology to deliver
industry leading long-term accuracy and reliability. These technology
features ensure optimum measurement stability for both periodic and
constant occupancy applications, so the device is equally suitable for the
classroom or the hospital room.

  • Page 1 Room Carbon Dioxide Transmitter SAE-1011 SAE-1012 Installation Instructions INTRODUCTION The room CO transmitter device uses a highly accurate and reliable non- room applications to monitor CO levels. The sensor uses dual channel optics and LTA (long term adjustment) signal processing technology to deliver industry leading long-term accuracy and reliability.
  • Page 2 The PCB must be removed from the base to access the mounting holes. Follow anti-static procedures when handling the PCB and be careful not to touch the sensors. The PCB is removed by pressing the enclosure base to unsnap the latch near the bottom edge, then the PCB can be lifted out of the base as shown in Figure 3.
  • Page 3: Output Scaling

    voltage signals are referenced to the COM terminal. The current output operates in the active mode and does not require a loop power supply (the signal current is generated by the transmitter and must not be connected to a powered input or device damage will result). The optional relay output connects to the RELAY terminals.
  • Page 4: Setup Menu

    When either the <UP> or <DOWN> keys are pressed, the LCD temporarily changes to display the temperature setpoint value in °C or °F as set by Temp Units in the Setup Menu. The display will show the previous temperature setpoint setting such as 22 ºC or 77 ºF. If no other action is taken for 5 seconds then the device will reset to normal operation.
  • Page 5: Output Test

    6. OUTPUT TEST The Output Test value controls the analog output signal for testing purposes. Use <UP> or <DOWN> to toggle the output signal to OFF (normal operation), MIN (minimum output) or MAX (maximum output). The actual output signal will Output depend on the PCB switch position (mA or VOLT) and the V Output setting (for Test OFF...
  • Page 6 Only if Relay option Installed 11. RELAY The Relay setting allows the relay alarm to be assigned to either CO High, Relay Low, Temp Hi or Temp Low as applicable. Use <UP> or <DOWN> to select. Factory default is CO High.
  • Page 7 Only if Setpoint option installed 16. SETPOINT MIDPOINT Use <UP> or <DOWN> to select the Setpoint Midpoint. Units are either C or F depending on the Temp Units setting. Setpoint Note that the setpoint has + or - 10 steps from the midpoint. Mid 21 °C For °C, the midpoint range is 18 to 25°C (resolution = 1°C, default = 21°C) For °F, the midpoint range is 64 to 77°F (resolution = 1°F, default = 70°F)
  • Page 8: Specifications

    Enter the Setup Menu and use the <MENU> key to advance to the “Calibrat” item. Press and hold either the <UP> or <DOWN> key for 5 seconds to start the gas calibration. The LCD will indicate “Calibrat / Done” if the process was successful. If “Calibrat / Fail” is displayed then the process may have to be repeated.
