Thank you for purchasing the InfraAlert System.The InfraAlert is manufactured under strict quality control standards using the best available materials. We hope you will be pleased with its all weather construction and excellent performance.

As an option, additional receivers and sensors may be used in conjunction with your InfraAlert product. This will allow you to place them in various locations for improved effectiveness. In addition, a very effective extension sounder can be readily connected to the receiver if required extending the audible range.

INFRARED SENSOR OPERATION:

The infrared detector is positioned behind the round lens. It has a pencil thin beam that is approx 12 meters long (at standard setting) and 20 meters when adjusted. The effective detection range of the sensor can be up to 12 metres.

The Infrared sensor detects vehicles, intruders, guests, inlaws & outlaws by sensing their heat and motion. When someone or something moves through he detection zone, the sensor detects the movement or intrusion and transmits a signal to the receiver.

INFRARED SENSOR INSTALLATION:

First, install the high quality, 9 volt, alkaline battery in the compartment located in back of the sensor. Securely close the battery cover. NOTE: Always use QUALITY ALKALINE Batteries.

Mount the sensor approximately 1 metre above the ground to a secure wooden post or side of a building etc, in a position thats is suitable for detecting the person/ vehicle that is entering. A metal bracket is provided for this purpose. Lightly grease mounting screws so they can be removed in the future.

The lens must have an unobstructed view of the coverage area. Extend the flexible antenna upward, some objects may not be detected if the sensor is pointed or placed too high or too low, adjustment may be required to optimise performance. Keep the sensor as close to the edge of the driveway as possible.

The sensor should be strategically located so that it detects objects moving across the detection zone.

CAUTION :

Do not mount the sensor facing the sun, bodies of water or any reflections. This causes variations in the temperature pattern ‘seen’ by the sensor and may cause false alarms or even damage the lens or sensor. Avoid situations where livestock through a fence can be ‘seen’ by the sensor causing false trips.

Note :

A shorter detection range may occur when the outside temperature falls below 6 degrees C. due to a natural drop in battery voltage. Lower sensitivity may occur during periods of fog, rain or snow. This is due to moisture diffusing the infrared energy. Sensitivity can be upped during times of heavy fog/ rain/ snow ect. The sensors and transmitters are rated to -
20 degrees C.

Detection Sensitivity

Optical sensitivity can be adjusted by means of the two switches on the right hand side of the address switches under the battery cover as follows:
Note: Do not alter the first five switches.

1 & 2 Off - Normal
1 On & 2 Off - sensitivity 2
1 Off & 2 On - sensitivity 3
1 & 2 On - Highest

RECEIVER OPERATION

Caution!

Use the InfraAlert power supply only as it uses a reverse polarity. Use of an incorrect power supply will void the guarantee and will cause damage to the receiver.

Situate the receiver on the transmitter side of the house near a window if possible. Insert the DC plug into the socket on the side of the receiver, and plug the transformer into a 230 volt AC 3 pin outlet.

Stand the receiver on a bench or mount it to a wall with the enclosed adhesive pad, and extend the flexible antenna upward.

The receiver will sound the alert when the sensor is activated. The alert sound resets itself after 6 seconds and will alert you with every detection of movement within the sensing range. The volume control can be used to change the sound level.

The receiver comes equipped with an accessory jack for the easy addition of an optional external sounder if a different sound or more volume is desirable.

The light emitting diode will light when the receiver is activated and will remain lit until the button is manually reset.

In a ‘Line of Sight’ situation, the reception range can reach up to 300 metres. Range may be reduced by certain obstructions. For instance; metal buildings, wire netting, dense hedges and trees etc. For maximum range. locate the receiver in an area in your home with some direct visibility to the sensor. (Close to a window perhaps) Be aware that metal or netting cladding (Roughcast or Stucco) will effect range capability. We have
1.5 Km and 3.0 Km kits avalible to over come this.

Walk Test

After setting up your system perform a ‘walk’ test to confirm the operational performance. Walk and drive through the detection area and have someone listen for the receiver to sound. The sensor can then be repositioned if not performing properly as required.

Address Coding Adjustment:

The system address coding is factory preset and should only require to be adjusted in the event of interference from another source. A DIP switch is located in both the senor and receiver. Only the first five positions on the switches can be changed and the switch settings in the transmitter must match the settings in the receiver. To open the receiver remove the volume control knob first. It will pull off.

As with all passive infrared devices certain weather conditions and other acts of nature may cause false alarms or reduce sensitivity. Below is a list of the most common problems and the solutions to solve them. PROBLEMS -can be caused by:

  • Use of low quality or non-alkaline battery.
  • Use of an old weak battery.
  • The sun shining into the sensor lens at a certain time of the day.
  • The sun reflecting off shiny objects into the sensor.
  • A poorly secured sensor. (Moves in the wind)
  • The sensor ‘seeing’ livestock in a paddock beyond.
