Set Detector Address
(also called Unit ID)
A Unique address must be assigned if the Detector is to communicate via RS485
to a PLC.
From the configuration menu select
Edit Address
option
In order to communicate digitally with a master controller on the data network
each detector must be assigned a unique address. This address is used by the
main controller to collect the information from the detector assigned with this
address. Typically the master controller sequentially sends out the request for
data to all the detectors on the network. The data request from the master
controller contains the sensor address. The sensor with this unique address will
respond to the request.
Follow the step by step instruction below to assign a unique address to the
sensor.
1.
To modify the detector address hold the magnet to its position as shown in
figure 9. The address will be incremented by 1 at a time. Remove the magnet
once the desired address value is achieved. The valid address value is
between 1 and 120. If pass the desired address value continue to hold the
magnet and the value will rollover to 1 after 120.
2.
A unique address is now assigned to the detector. This address will be
retained in a non-volatile memory until modified by the user.
