Vertical Adjustment
To position the PCB, turn the Easy Lock counter-
clockwise and slide the PCB up or down to the required
setting using the vertical adjustment scale. The
detector’s coverage area is 12m x 12m when the PCB is
positioned at 0. Slide the PCB up towards the -8 position
to decrease the coverage area bringing the beams closer
to the mounting wall.
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 s
Figure B.2: Lens Coverage Diagrams
elected.
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.
LED Indication MS845

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.
