1 Brief introduction
VAN300 gas alarm system, consisting of VAN300 panel and 1～3pcs detectors, is
designed especially for detecting leakage of CO, combustible gas and aether inside the
recreational vehicles. It adopts high-quality air-sensitive component and advanced sensor
technology. When the gas concentration reaches the presetting alarm level, it gives out
visual and audible signals, which reminds the user to take prompt favorable action.

6 Operation instructions
6.1 VAN300-CO
6.1.1 Connect it with the power supply, and Power LED and Fault LED turn on. The system
starts warm-up: 3 minutes for panel and 5 minutes for detectors. During warm-up, the
detection function doesn’t work. After 5 minutes, Fault LED turns off, and the system
enters detection status. Power LED of the panel turns on, and the Power LED of the
detectors keep flickering.
6.1.2 When CO concentration reaches the presetting alarm level, Alarm LED of the
detectors flickers, and the detector sends alarming signal to the panel. Then the panel
gives alarming:Alarm LED flickers, buzzer gives sound alarming, and it drives relay output.
It can also drive the external speaker or alarming light if have.
6.1.3 When CO concentration is lower than the presetting alarming level, all the alarming
disappear and the system returns to the normal detection status.

6.2 VAN300-LEL
6.2.1 Connect it with the power supply, and Power LED turns on. The system starts
warm-up for 3 minutes. During warm-up, the detection function doesn’t work. After 3
minutes, the system enters detection status. Power LED of the panel turns on, and the
Power LED of the detectors keep flickering.
6.2.2 When LPG concentration reaches the presetting alarm level, Alarm LED of the
detectors flickers, and the detector sends alarming signal to the panel. Then the panel
gives alarming: Alarm LED flickers, buzzer gives sound alarming, and it drives relay output.
It can also drive the external speaker or alarming light if have.
6.2.3 When LPG concentration is lower than the presetting alarming level, all the alarming
disappear and the system returns to the normal detection status.
6.3 Fault alert
Once the wire connection is not good or short circuit occurs, Fault LED of the detectors
turn on, and the detectors send signal to the panel. The panel gives visible and audio
alarm. Fault LED of panel turns on, buzzer gives sound alarming. It can also drive the
external speaker or alarming light if have. When there is fault alarming, the system
detection function doesn’t work.
