Subnetwork Bus Total Length
The total maximum length of all Subnetwork buses, including both the length of the Allure Series Communicating Sensor Subnetwork bus and the
ECx-400 Series Subnetwork bus is 300 m (1 000 ft). The maximum length of the Allure Series Communicating Sensor Subnetwork bus is 200 m (650 ft).
The maximum length of the ECx-400 Series Subnetwork bus is 300 m (1 000 ft).

Subnetwork Bus Overview Showing the Allure EC-Smart-Vue Subnetwork Bus and the ECx-400 Series Subnetwork Bus.
A controller can support a maximum of two Allure EC-Smart-Vue sensor models equipped with a CO
without a CO
sensor. See Table 1 for the quantity of room devices supported by each controller model.

For instance, if the controller model supports a subnetwork with 12 Allure EC-Smart-Vue sensors in total, then 10 sensor models must be without a CO2
sensor and the other two can be equipped with a CO2 sensor. To ensure proper operation, it is recommended to distribute the sensors throughout the
length of the subnetwork.

For ECB/ECL-PTU Series controllers, the maximum length between two consecutive devices on the sub-network bus
is 100 feet (30 m).
