CONFIGURATION PAGE FOR RELAY SETTINGS
You can use the configuration page for relay settings to specify parameters such as normally open or normally closed switching and
bistable or monostable operation of the output.
Figure 33. Configuration Page for Relay Settings
The relay settings are described in the following table.
Table F. Relay Settings
Configuration Default
Description
Item Setting
Idle state Open Select Open (N.O. at zero current) if the relay will operate as a normally open contact or Closed (N.C. at zero
current) if it will operate as a normally closed contact.
Operating mode
Bistable Select the relay’s operating mode.
• When you select the default Bistable mode, the relay will stay in the idle or active state for an indefinite period.
(For example, select Bistable if a floodlight activated by an alarm is to remain switched on at the end of the
alarm.)
• When you select monostable mode, the relay automatically falls back to the idle state after a predefined period
expires. (For example, select 10 s if a siren triggered by an alarm is to sound for 10 seconds.)
The choices on the pull-down menu are: Bistable, 0.5 s, 1 s, 2 s, 5 s, 10 s, and 60 s.
Relay follows Off Select from the pull-down menu an event that will activate the relay. A typical application is having the relay
following the status of the alarm input; for example, to power peripheral equipment or even the camera itself.
Select from the following:
• Off: Relay does not operate.
• Connection: Relay operates whenever you open live video and will turn off once you exit live video.
• Video alarm: Relay operates when there is loss of the video signal.
• Motion alarm: Relay operates when there is motion alarm.
• Local input: Relay is operated by an external alarm sensor.
• Remote input: Relay is operated by a switching contact from a remote location.
Relay name Relay 1 Enter a name for the relay that will appear on the Live page.
