SEQUENCE
Sequences Overview
Sequences are used to perform Actions in response to Events.
The Event can be triggered automatically by, for instance:
• A Time of Day Schedule
• A Video Loss Alarm and Restore
• An Alarm Point changing state, going Open or Closed
• An Operator Log-In and Log-out
• A Keyboard being Logged In or Connected
• By a third party message such as an Access Control System (i.e., Invalid card
usage, or Forced Door Alarm).
A sequence can be also activated manually by a User Defined key.
A Sequence can perform simple tasks such as:
• Switch a specific Camera to a designated Monitor
• Lock or unlock and electric latch by activating a control relay output.
Sequences can also perform complex functions using multiple steps and incorporating
conditional logic.
For instance, if there is an alarm then switch a specified camera to a designated monitor
BUT if it is between 6pm and 6am then switch that camera to a different monitor...
A typical Sequence would be:
There is an alarm from Input #8 (being a door status monitor switch)
Switch camera 17 to monitor 8
Display a text message on monitor 8 (Forced Door Alarm) for 5 seconds
Sound the alarm "beep" on keyboard 4 for 5 seconds.
Sequences use message numbers, so they are closely linked with defined Messages.
Messages may be created first, and then used in sequences, or sequences may be
created first, followed by creation of the messages they reference.
