Overview
Mounting and Wire Connection
- Notice the supply power voltage of the detector: 24VAC. Do not install the detector on voltages higher than marked on the detector.
- Firstly, prepare a flat head screwdriver and put it inside of the hole on the top of the detector housing following step 1, and then open the cover from step 2 to step 4 in next page fig.1.
- Mount the wall plate first, dimensions see next page fig. 2.
- Connect wires to terminal strips, (see fig. 3).
- Follow step 5 to step7 in fig. 4 to close the cover.

Select CO2 level to Control the Relay
The CO2 level for control the relay turning on has been set to 1200ppm. If you need to change the CO2 level, open the cover after switch off, you may see two jumpers (J4 and J5) on the top of the circuit board and under the CO2 module. Take off the CO2 module, you can select the CO2 level to control the relay on /off by jumpers as below table.
| Jumper | CO2 level | Relay turns on /turns off |
| J4-disconnect; J5-disconnect | 800ppm | CO2>900ppm,the relay on; CO2 <700ppm,the relay off |
| J4-connect; J5-disconnect | 1000ppm | CO2>1100ppm, the relay on; CO2 <900ppm, the relay off |
| J4-disconnect; J5-connect | 1200ppm (default) | CO2>1300ppm, the relay on; CO2 <1100ppm, the relay off |
| J4-connect; J5-connect | 1400ppm | CO2>1500ppm, the relay on; CO2 <1300ppm, the relay off |
Important Instructions:
- Don’t shake or hit the CO2 unit too much in shipment or in mounting to protect the internal infrared CO2 sensor from any damage and excursion of infrared receiver.
- When open the cover of the CO2 unit, you’ll see one PCB board mounted over another bigger PCB board. This upper small PCB board is loaded with CO2 sensor. Don’t uninstall the CO2 module without instruction from our engineers, in order not to cause any damage to the CO2 sensor. Please note: the pins on the CO2 module which connect with the bigger PCB board have direction. Wrong connection will cause the CO2 module and processor damage.
