BM 25A/AW
AREA GAS MONITOR
USER MANUAL
28 NPB25AEN
Revision D.0
Thereafter, in normal operation, each BM 25AW sends its information over the network every
ten seconds. If a BM 25AW goes into gas alarm or fault condition, then the information is
immediately sent without waiting ten seconds. In
BM 25 mode, the number of BM 25AWs that
are communicating on the network is shown at the bottom of the display screen (example 4
shown below).
Figure 27a –
BM 25
mode : Four BM 25AWs
communicate with each other on the same network
Figure 27b – Controller mode : BM 25AW is
communicating with the controller
When in
BM 25 mode, BM 25AW displays the radio signal strength as indicated below in
figure 27c. It corresponds to the average of signals received from all BM 25AWs that the BM
25AW you are looking at is communicating with.
Figure 27c –
BM 25
mode : Radio Signal Strengh
When is displayed, the BM 25AW has 100% of the signal and the radio communication
is very good.
When is displayed, the signal strengh is less than 20% although BM 25AWs are still
communicating.
When is displayed, no communication is established, BM 25AW shows 'COMM ERR'
and goes into fault (see case #1 from table of events).
4.2.1 Adding a BM 25AW on an existing network
In
BM 25 mode, the network is automatically built. Each BM 25AW with the same network ID is
automatically included as long as it communicates with at least one BM 25AW belonging to the
same network.
To add a new BM 25AW to an existing network, simply turn the unit on, activate the radio
communication and, if applicable, set the network ID.
In MODBUS mode, you must set the address number (Slv Nb), set the network ID (Channel)
and configure, if applicable, a new input on the controller.
