How it works: The Vehicle Alert is a simple to use vehicle motion detection system that operates on the principle that any moving ferrous metal object will distort the Earth's magnetic field to some degree. The technology used to measure this distortion is one of the most reliable forms of outdoor protection available. Unlike other outdoor motion detectors that sense heat, vibration or change in position of an object, the Vehicle Alert will sense only moving iron or steel. This makes the Vehicle Alert a selective sensor, reducing the possibility of false alarms from animals, falling tree branches or people in an outdoor environment. By selectively placing the Vehicle Alert sensor, you can detect cars and trucks entering or leaving an area as well as the movement of a parked vehicle such as your car, a boat or motor home. Objects not constructed of iron or steel can also be monitored by equipping them with a large magnet. When the object is moved in the immediate area of the sensor probe, the Vehicle Alert will activate.
Exit Delay: The exit delay button is used to disable the Vehicle Alert for a period of about six minutes, this delay can be used to allow someone to leave the monitored area without activating the buzzer or any of the other accessories connected to the Vehicle Alert.
Accessories: Additional buzzers, part # 1175 can be located throughout your home or shop. Since the console contains two dry contact relay outputs it can be connected directly (no need to use relay modules) to a door bell, wireless transmitter, or hardwired alarm zone to create other types of alarms. For higher voltage alarms such as sirens etc. use Relay switching module part #1176
Wireless remote buzzer: With the optional remote wireless modules you can have a second buzzer. Modules shown below.
Protect Driveways up to 20' wide: The Sensor Probe should be buried at a depth of 6 to 8 inches, parallel to the driveway to protect drive up to 20' wide, if the drive is wider than 20' you should place the sensor in the middle of the drive or one sensor (two can be wired to the console) on each side of the drive or monitor two drives. The sensor probe covers an area approximately 15 feet parallel to the probe when activated by a full size automobile, this area will vary depending on vehicle size and speed.
Where not to place the sensor: The sensor probe should be away from high speed traffic, railroad tracks, motors, transformers, radio transmitters, sources of strong magnetic fields, or other moving iron or steel items, otherwise false alarms may result.
Installing the Sensor Probe: If the driveway to be monitored doesn't exceed 20' in width, we recommend that the sensor probe be buried along side the driveway (parallel to the drive) The advantages of this are: sensor probe needs to be buried only 6 to 8 inches below the ground level. The cable back to your house or office can be buried at any depth that will not interfere or be damaged by yard maintenance, for extra protection you can place the cable in 1/2" PVC pipe, another advantage of installing beside the drive is to eliminate the possibility of crushing the sensor probe when it is buried beneath unpaved driveway. |
