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 (transmitter only).
•Motion alarm: Relay operates when there is motion alarm (transmitter only).
•Local input 1: Relay operates by an external alarm sensor.
•Remote input: Relay operates by a switching contact from a remote location.
•Unified picture: Relay operates by loss of focus on the camera (transmitter only).
