6.4 LCD/LAMP (LED) TEST

A number of different test patterns are displayed on the LCD.
At the same time as the LCD test pattern is shown the LED indicators on the front panel
(except the “MAINS ON” LED) will be flashed on for half a second, off for half a second,
for 5 seconds.
After the front panel LEDs and LCD have been tested, the zone (and relay) LED display
boards will be tested, one board (16 zones) at a time. Each display board will be tested
for about 3 seconds and all 48 LEDs on the board will be turned on and off
simultaneously with half a second on and half a second off.
The testing of the LED display boards can be terminated by pressing "RESET".
The test can be paused or resumed at a particular display board by using the "ISOL" key.
The test can be stepped to the next display board using the "ACK" key. The "ACK" key
can be used to step to the next display board when the test is in pause mode.
NOTE:
For an NDU in New Zealand mode a Lamp Test can also be started by momentarily
shorting the LAMP TEST input on the Display Extender board to 0V.
