Alarms and Events

Speed of alarm notification
After you have set events to “alarm”, and alarm hardware connected to the video unit is
triggered, notification of the event is either:
• immediate. Your Multi-Media units are networked to the alarm station or an
alarm session is in progress at the site where the alarm occurs. Note that units
using dial-up connections monopolize an operator’s modem: it is not possible
to run alarm sessions at many of these sites, at the same time. Until the alarm is
rearmed, more occurrences of the event are ignored. However, you can record
multiple occurrences of an event by silently logging them. See 6.8.2: Logging
Events Silently.
• within the minute. Your Multi Administrator has set the video unit to “call” an
alarm station, as soon as possible after an alarm. You are notified of the alarm
whether or not an alarm session is in progress at that site. Should the alarm
station be unavailable or busy, an attempt to call it back is made every minute
until a connection to View is established. When more than one alarm station is
assigned, they are polled in sequence.
- or -
• deferred. When a Multi-Media unit is not assigned to an alarm station, the unit
“holds” alarms until you start an alarm session for the site.
Alarm doubling
When a Multi-Media unit has been setup to call back an alarm station, and you happen
to be running an alarm session at the alarm station, an event at the site triggers a call
and an alarm.
