Setting Description
Idle state Open Select Open (N.O. at zero current) if the relay will operate as a normally open contact or Closed (N.C. with 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 a time period (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 to have the relay follow
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 when 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 operates by an external alarm sensor.
• Remote input: Relay operates 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 (31 alphanumeric characters maximum).
Trigger relay N/A Click the Relay button to switch the relay manually (for example, as a test or to allow a door to be opened).
