PROGRAMMING INSTRUCTIONS CONTINUED
Light Sensor
•
The light sensor tells the system to stop broadcasting at night to save power and to
reduce noise nuisance.
•
The DUSK timer runs for 1 hour at sunset to keep the system active after sunset to
discourage birds from roosting.
•
The DAWN timer delays wakeup of the system for 60 seconds to ensure that the
system is not triggered by passing motor vehicle headlights at night.
Light Sensor: Test
•
Briefly press one of the light sensor buttons to disable the dawn / dusk timers.
•
Cover the light sensor (positioned on left hand side of speaker below keypad) with
hand - the Amber LED should go out indicating the system is in night mode.
•
Remove your hand and check the LED now goes to a solid Amber colour – this
indicates the system is now in day mode and the light sensor is working correctly.
•
During normal operation, the light sensor LED will be on during daylight, it will flash
when dawn or dusk timer is running and will blink once every 5 seconds if in night
mode (to save power).
Light Sensor: Adjustment
•
Adjust Light Sensor by pressing the associated “up/down” buttons repeatedly as
required; 1 = most sensitive to light, 10 = least sensitive.
•
The light sensor level will be shown on the number LEDs while operating the buttons
and for a few seconds after release.
•
Minimum setting disables the light sensor. This is achieved by adjusting the light
sensor down until LED No 1 also goes out - this is confirmed by rapid flashing of all
number LED’s.
Light Sensor: Other
•
Pressing the UP or DOWN buttons briefly will bypass the dawn and dusk timers
when in "Dawn/Dusk" Timer mode (e.g. amber LED is flashing). This allows the
system to go into night mode immediately if dark, or day mode if daylight, without
the delay.
