Walk Test Mode

A walk test is performed in order to determine the lens coverage pattern of the detector – see Figure B.2. Walk Test mode cancels the delay time between detections, enabling you to perform an efficient walk test.

To perform a Walk Test.

1.Place the Mode jumper over pins 1 & 2.

2.Walk across the scope of the detector according to the detection pattern selected.

3.Confirm that the LED activates and deactivates accordingly. Wait five seconds after each detection before continuing the test.

4.After completing the walk test, remove the jumper and place it over one pin for storage – see Mode Jumper Safeguard.

LED Indication

The LED indicator is lit twice every time a transmission is made. To enable or

disable LED indication, refer to Table B.4 below.

The LED should only be disabled after successfully walk testing the detector.

Mode Jumper Safeguard

During normal operation, the Mode jumper should be placed over one pin for storage. When the mode jumper is placed over two pins, the detector is either in Radio or Walk Test Mode. As a precaution, these modes are limited to three minutes. After three minutes have expired, the detector switches back to normal operation. If this happens, you can reset a mode by removing and replacing the mode jumper.
