• On-board Relay and menu driven set-up
• Solid-state reliability
• Small compact size
• Solid, reliable mounting method
DESCRIPTION:
The CO2 monitor uses a highly accurate and reliable Non-dispersive Infrared (NDIR) sensor with state-of-the-art
digital linearization and temperature compensated circuitry in an attractive, low profile enclosure for room
applications to detect CO2 levels and provides a linear analog signal output of 4-20 mA, 0-5 or 0-10 Vdc signals. An
onboard relay can provide a control signal based on a high limit setting. Parameters are set up via momentary
pushbutton (keypad) and the LCD display which is also used to display current reading.

CO2 Sensors 023-0388 Installation
For leak detection install the CO2 sensor on the rack at 12” (30cm) from floor.
One 24VAC transformer can be used for many CO2 sensors only if the common side is on the same side of the
transformer (Calculate 3VA per CO2 sensor).
The CO2 sensor 023-0388 reading range should be factory set to 0-6000ppm, output set to 4-20mA. When powering
the sensor, the setting must be checked. To check press the Menu button. If these are not the settings make the
changes as follow:
Set Transmitter switch to mA (4-20mA).
Press on MENU repeatedly to choose option, press on UP or DOWN to change value. Value is saved when MENU
is pressed again. CO2 Span = 6000 PPM (Range)
Self-Cal = On
Relay CO2 = High
Relay SP = 4000 PPM (Relay On )
Relay Hy = 200 (Hysteresys to have Relay Off @ 3800 PPM)
Relay Dly = 0min
To exit press MENU until you see current CO2 ppm reading.
Connect the signal on 4-20mA mode with 470-0300 255 ohms resistor at the Sensor Node input to reduce the
reading variation of PPM caused by the wire length.
Option: Use a MT-Display 961-462C to display the PPM remotely. Power it on any 24V transformer (see
installation documentation for Case Display PUID 72-MTA-1003.
Install sign 905-0012 “If the value shown exceeds 5000 ppm DO NO ENTER”above the MT-Display.
Make the connections by following wiring instruction of a manual pull station 961-0001.
Make bindings between nvoUniversalX of the Sensor Node and nviPPM of the MT-Display.
Create model on Alliance see section Adding a CO2 sensor model or PUID 72-MTA-1010.
Set the High limit to 2500ppm and Low limit to 50ppm with a delay of 0 and a low priority.
