NOTE: Insulating glass are metallized, the field of the sensor can be affected.
The MS508 should be placed as close as possible to the center line of the vehicle. The mounting tabs should be to the front and the rear of the vehicle, but the orientation of the wire-socket end is not a factor. Also, the MS508 is not sensitive to being placed directly onto metal. Please pay attention to the subsequent accessibility of the trimmer for the adjustment.
The MS508 will not trigger during the first 4 seconds of being turned on. This prevents the user from triggering the voice immediately after arming the system, and avoids several possible installation difficulties. When adjusting the MS508, always set the warn-away adjustment first. This will expand or contract both zones. After this adjustment has appropriately defined the outer zone, then use the trigger adjustment to set the inner zone.
When the sensor send a (-) 200mA trigger on the green warn-away wire, the green LED will turn on. When the sensor sends a (-) 200mA trigger to the blue trigger wire, the red LED will light.
