DUAL ZONE MICROWAVE SENSOR - INTERNAL ZONE AND EXTERNAL WARN AWAY ZONE. 

Protect your vehicle with an invisible sensing field which only detects 3 dimensional objects near your car using Radio Frequency (RF) field disturbance technology. Ideal for convertibles, or any application where zone-intrusion protection is desired. Violation of the outer field can provoke siren chirps when used with an appropriate siren with warn away input, while intrusion into the inner zone will trigger the alarm system and trigger a 30s alarm cycle. The DS-508A uses an ultra-high frequency to detect objects of sufficient mass which move within a defined area. The field extends through the vehicle upholstery, glass, plastic and wood, but is blocked by metallic objects

 
NOTE: Certain cars use glass which can inhibit the external zone from working effectively, please consult your installer for more information. 
 
INSTALLATION
The DS-508A should be placed as close as possible to the centre 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 508A is not sensitive to being placed directly onto metal. Please pay attention to the subsequent accessibility of the trimmer for the adjustment. 

ADJUSTMENT 
The DS-508A Dual Zone Microwave Sensor will not trigger during the first 4 seconds of being turned on. This prevents the user from triggering the system immediately after arming the system, and avoids several possible installation difficulties. When adjusting the 508A, 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 inner zone adjustment to set the inner zone.

 
When the sensor sends 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.
