OM200-Alarm

Quick Overview

OM200 multiplexer Interface
Alarm Monitor for up to 8 interface cards
When reliability is a must

Product Description

This interface monitors up to eight interface cards in a chassis for communication failures. This card is used when data communication integrity is a must. Each of the Alarm card’s eight relay contacts can be configured to close when a particular card in the chassis fails; these contacts can be connected to an external alarm such as a buzzer. Interface card failures include, loss of synchronization, loss of connection with the remote partner card, loss of power, removal of the local or remote card, and hardware faults. It is only necessary to monitor one end of a communication link, as the alarm contacts will close if the failure is local or remote.

The optical cards have a contact which closes on network failure; this and any number of alarm contacts may be wired in parallel to create a single alarm point. These alarms may be transmitted to a remote location by pairing this card with another OM200-Alarm card (or with the OM200-Contact card). A contact closure on the Alarm card will then close the same contact on the remote card. To set this up, use the network management interface as follows:

1. Set the alarm input node to “Monitor LOCAL alarms”.
2. Set the alarm output node to “Monitor REMOTE alarms”.
3. Set up a Data Connection between the local and remote card.

This interface may be used in an Add-Drop topology where one or more input nodes share a channel which shows up at one or more output nodes. An alarm at any of the input nodes closes the corresponding contacts at the output nodes. All of the input nodes must be adjacent to each other, and all of the output nodes must be adjacent to each other. To set this up, use the network management interface as follows:

1. Set the input nodes to “Monitor LOCAL alarms”.
2. Set the output nodes to “Monitor REMOTE alarms”.
3. Set up a Data Connection between each card and any other card in the chain.
