WebMon alarms are highly detailed. Each alarm is data based with its exact location including the site, the device and a plain English description of the alarm. Alarms can be set to any one of four severity levels: Critical, Major, Minor and Status. Each alarm has an accurate date and time stamp which is stored in the WebMon”s event history.

The WebMon Edge and Matrix detect state changes. They read standard discrete states, and calculate derived discrete states and analog readings. Analog readings are separated into states using thresholds. Four user-configurable thresholds divide the readings into five distinct states.

All WebMon products report “changes of state” on monitored inputs. In addition, the Edge and Matrix will report “derived” alarms based upon multiple discrete and analog inputs. Changes in analog inputs are reported when the voltage crosses up to four user-defined thresholds. The five possible states are High-High, High, Normal, Low and Low-Low.

Both the WebMon Edge and Matrix allow the end user to create customized alarms based on multiple alarm inputs. A derived alarm is beneficial when a combination of problems happening at once is more critical than any one problem happening by itself. For example while a generator failure or a low backup battery may not be a critical alarm by itself, it does become critical if both happen simultaneously. The Edge and Matrix can be configured to treat these alarms as Minors when they occur separately but then as a Critical when they happen at the same time.

Derived alarms are user-configured through simple Boolean equations using AND/OR logic. Derived alarms can combine alarms from your equipment anywhere in your network.

With the Edge and the matrix you can use alarm inputs to trigger automatic control relay actions. Both ordinary and derived alarms can be used as derived control inputs. As an example, the Edge or Matrix could be configured to automatically start a site generator if there is a low battery alarm. Additionally if a derived alarm signaling that a battery is low and the generator is down could trigger an automatic email alert.

You may have equipment in your network where a self test is scheduled to happen on a fixed date and time and you may not wish to be notified every time a successful self-test occurs. However if the self-test did not occur as scheduled you do want to know.

Both the WebMon Edge and Matrix can “ping” up to 32 ICMP Network Elements. An alarm will be declared if the network element fails to respond to a ping within a user-specified interval.

Both the WebMon Edge and Matrix can send an event notification with email or SNMP traps. One email is sent for each event, with up to 16 recipients. One trap is sent for each event, with up to eight recipients.

Our four-port Ethernet Switch/Media Converter module is an available option on both the WebMon Edge and Matrix. Its supports auto negotiation and optionally converts between 10/100 BaseT(X) and 100BaseFX segments of the network. The available options include all copper ports or a combination of cooper and fiber ports. The fiber ports of the Media Converter/Switch are available in single mode, single or dual fiber and multimode dual fiber length ranging from 1.2 miles to 24.9 miles.

The WebMon Edge and Matrix both include a scheduling feature that can be used for a maximum of four alarms. End users may wish to use this feature for intrusion alarms. You may set a schedule by day and by time of day to ignore an intrusion alarm.

In the event of an Ethernet network failure both the Edge and Matrix support up to four dial-out targets, each with its own phone number, login name and password. Each SNMP target can be assigned to any one of the dial out targets, or to none. Each SNMP trap can be assigned to use dial-out always, never, or on an as-needed basis.
