Network Configuration
Using CAN Network with No central controller (master/slave operation)
One of the 60XX series gas sensors can be used as the controller. It can activate the ventilation for all the sensors, or a group. The use of a
dedicated controller is optional, - to add a display in some specific location, such as before entering a mechanical room or to interface with
several fan starters located in one place. Starters and air dampers are connected to the sensor closest to it in each zone.
Default Configuration
Sensors are shipped pre-loaded with default settings which can be changed in the field to suit the desired sequence with simple keypad
input. When a sensor goes into alarm level 1, 2 or 3 it activates its relays and transmits a message to all other sensors to activate their relays
also. The ventilation system can be connected to any of the relays (usually level 1). This is a configuration for one ventilation zone.
Creating Zones or groups
To control multiple zones on the same network, set the transmit message on each sensor to different messages for different zones. The default
transmit messages are 1, 2, 3 for alarm levels 1, 2, 3 for zone 1.
Set zone 2 sensors to transmit messages to 4, 5, 6
Set zone 3 sensors to transmit 7, 8, 9 and so on.
Addresses
Set each sensor and controller to a different address (setting 39). 1, 2, 3, 4 etc. It is important to have no duplicates on the same network
cable.
Output Relays
Relay number 1 and 2 will activate if the gas on that sensor goes into alarm level 1, or 2. It will also activate when it sees its receive code
(setting 36, 37) on the network, sent by other sensors.
-A models only have 1 relay.
The controler has no sensors on board so the relays will only activate if it sees its receive codes on the network. The 6000 controller could
control two zones via its two relays. When no controller is used, the master needs to be a member of the group it is controlling.
