Get to the menu

1. Press the menu button on the remote and enter the password (default is 6666)


2. Choose the menu options: Alarm → Sensor

Setting	Options	Explanation
Channel	S1 . . S4/S8	This refers to the alarm input wire, so S1 is alarm input 1, S2 is alarm input 2 etc.
Enable	☑ ☐	Lets you enable and disable individual triggers, so if you only want trigger 2 to be active, you can enable that one and leave the rest disabled.
Sensor Name	User Input (4 letters)	You can give the alarm a friendly name here, it is what will be displayed on the screen if the OSD setting below is ticked. This could be something like Rev for the reversing alarm.
Trigger level	HIGH LEVEL LOW LEVEL	HIGH LEVEL The alarm will activate when a 12/24V signal is fed into the alarm input LOW LEVEL The alarm will activate a 0v signal is fed into the alarm input, so a 12/24V signal will turn the alarm off
Linkage	OFF CH1 . . CH4/CH8	Lets you make a camera full screen when the alarm is active. The recording will still record all connected cameras, it's only the live display for the driver that is affected
OSD	☑ ☐	This will show the Sensor Name on the display while the alarm is active.
Alarm	☑ ☐	This setting is used for different models of the DVRs which we do not supply.
Lock	☑ ☐	Lock the file with the alarm on it so it won't get overwritten when the storage is full.
Alarm out	☑ ☐	This will cause the output relay (connecting Alarm Output COM1 wires) to activate when the alarm is active.

If, for example, you have a reversing camera connected to channel 4, and you have a reversing feed (reversing lights is a good one) on alarm input 4, you would have it set up like so:

Setting	Option
Channel	S4 (for alarm input 4)
Enable	☑
Sensor Name	Rev
Trigger Level	HIGH LEVEL
Linkage	CH4 (make camera 4 fullscreen)
OSD	☑ (Doesn't matter)
Alarm	☑ (Doesn't matter)
Lock	☑ (Doesn't matter)
Alarm out	☑ (Doesn't matter)

Alarm input and output

The 0-776-80 and the 0-776-81/84 have slightly different wire layouts for the inputs and outputs. Here are the diagrams:

The alarm output COM1 has a relay inside that closes when the alarm output is active. Alarm output COM2 is not used.
