Connect multiple additional sensors

How you connect extra Sensors to an existing LogiCO2 Safety System

You can connect multiple CO2 or O2 Sensors to a LogiCO2 Safety System. Set the ID-address in the Sensor/Sensors (Observe – never the same ID address in two sensors) with the DIP switches in the Sensors, and also set the number of connected Sensors with the DIP switches in the Central Unit.

Setting the ID to LogiCO2 Sensors and Central Unit

This video explains how to easily configure the Central Unit and the Sensors during larger installations, with multiple sensors.
For exact configuration of the DIP-switches, please see the product manuals or read the settings below.

DIP-switch settings in the Central Unit, Number of connected Sensors

The Central Unit only has one DIP-switch and the number of connected sensors is set via Dip 1-4.
NOTE! Dip 5-8 are not in use and must be placed in “OFF” position.

Default functions/settings in the Central Unit: Connection to one Sensor.
All dips are set to OFF position as default.

DIP-switch settings in the CO2 Sensor, ID-address 1-12

The CO2 Sensor has two DIP-switches. Please observe that the ID-address is set via DIP-switch 2, Dip 3-7.

Default ID-settings in the CO2 Mk9 Detector Base SET: ID1
Default ID-settings in the CO2 Mk9 Sensor Add-on KIT: ID2
If you have two or more Sensors already connected in the alarm system, please set the dips according to this table:

DIP-switch settings in the O2 Sensor, ID-address 1-8

The O2 Sensor only has one DIP-switch. The ID-address is set via Dip 1-3.

Default ID-settings in the O2 Mk9 Detector Base SET: ID1
Default ID-settings in the O2 Mk9 Sensor Add-on KIT: ID2
If you have two or more sensors already connected in the alarm system, please set the dips according to this table:
