3.5 Client Monitoring
The NFN-GW-EM-3 is able to monitor connected clients. When the NFN-GW-EM-3 detects a monitored client has disconnected, the
NFN-GW-EM-3 deactivates the output relay. An active relay indicates that the client is operating properly. If power is disconnected from
the gateway, the lack of the active relay results in a trouble on the connected monitor module.
The client monitoring feature operates as follows:
• When a client connects, the gateway adds the client to the list of supervised clients.
• The user may log into the gateway and deselect one of the clients which was automatically added to stop the gateway from
supervising that particular client.
• The user may log into the gateway and deselect the option which forces the gateway to automatically add clients to the
monitored clients list when it connects.
Use cases are covered in the following table:
Table 3.5 Client Monitoring Use Cases
Case
Procedure
Supervise all site clients at
the gateways. No gateway
configuration.
1.
Connect the output relay to an input module on an FACP.
2.
On the FACP, configure the input as a trouble (tracking recommended).
Note:
All clients at the site must have fixed IP addresses.
Supervise specific clients
at the gateway.
1.
Connect the monitored clients to the gateway. The clients must have fixed IP
addresses.
2.
Open the gateway’s web-based configuration tool.
3.
Deselect the option to automatically add and monitor clients as they connect.
4.
Deselect any specific clients that do not need to be monitored (if any have been
added).

If new clients are added and are to be monitored, re-enable the automatic
addition/supervision and connect the new client(s). Once they have been added, turn
off the automatic addition option.
