10.5 Sensor Addressing
ESCO-TDFS has a fixed device address of 199 on the SA Bus. The
address can be changed on other models via DIP switches on the PCB
rear. The designation of each address is shown in the following table.

Room CO2 Sensor Module
Each sensor on the SA bus must have a unique address. The default
controller strategy is preconfigured to automatically detect all Room
Modules on the network and react accordingly.

10.7 Interconnection
The sensors or other devices on the SA bus network connect either by
modular RJ12 connections or by screwed terminals using plain ended
cable. All sensors are fitted with both.
10.7.1 Modular Cable (Up To 30m)
The Room Modules can connect using a 24AWG twisted 3-pair cable
with RJ12 connections over the Sensor Actuator (SA) bus. the following
items are available.
ESCO-C3M
3m Prefabricated sensor cable with modular jacks
ESCO-C5M
5m Prefabricated sensor cable with modular jacks
ESCO-C10M
10m Prefabricated sensor cable with modular jacks
ESCO-C20M
20m Prefabricated sensor cable with modular jacks
ESCO-C30M
30m Prefabricated sensor cable with modular jacks
ESCO-2WA
2-port extension adapter
ESCO-3WA
3-port extension adapter
Room Modules must not be fitted more than 30metres (cable length)
from the controller when using this connection method.
10.7.2 Plain Cable (30 - 150m)
If a Room Module is to be fitted more than 30metres (cable length)
from a controller, the following cable is recommended.
ESCO-MSTPC30M
Ecosmart Connect MSTP cable reel 30m
ESCO-MSTPC150M
Ecosmart Connect MSTP cable reel 150M
On the SA Bus, the + and - wire are one twisted pair, and the COM
and SA PWR are the second twisted pair of wires.
These cannot be used with RJ12 connections and must be stripped and
connected using screwed terminals. The shield must be earthed at the
control panel end only and be made continuous along the bus length.
Room Modules must not be fitted more than 150metres (cable length)
from the controller.
