audible alarm sounds in addition to visual alarm and alarm relay. To stop the audible alarm,
switch panel off or switch over to the alternate power supply.
Note: If main supply is present, main supply must be selected to avoid alarm.
Outgoing circuits
The TEF4732 series is delivered with 2x9, 2x13 or 2x16 outgoing circuits. Each circuit contains a
separate monitoring device. The circuits are switch by a two pole rocker switch, left position –
main output, centre - off and right position – spare output.
Each circuit has a corresponding LED to show status. LED off – Circuit off. Steady light – Output is
on and circuit is OK. Flashing light – Output is on and a failure is present. Failure can be a broken
bulb, blown fuse etc. When a failure occur an audible alarm and the alarm relay activates. To
stop the alarm, correct failure or switch circuit off.
When spare output is on a red LED lights up next to the respective switch.
Each circuit is fused in both poles. The fuses are located in the outgoing terminal blocks.
Dimmer, test button, potential free alarm contact
Indicator LED’s for the outgoing circuits are dimmable. Dimmer knob is located at the bottom left
side. LED’s for power supplies are not dimmable.
Next to the dimmer knob, a push button named ‘test’ is located. This button tests the function of
indicator LED’s and buzzer. When pressed all LED’s lights up and buzzer is sounding. Note: The
‘test’ button does not check the status or functionality of the circuits or connected navigation
lights.
The panel is equipped with a potential free change-over contact which activates on all alarms.
The alarm contact is connected to terminal No. 51, 52 and 53.

Installation
All systems are custom made. Refer to drawings for the specific system for connection
diagram.
Power supplies
The panel should be supplied from two dedicated circuits, one from main distribution board and
one from emergency. The power supplies must be fused.
Dimensioning fuse and cable depends on number and power of navigation lights connected. Add
up power of main navigation lights and add 20W for total power for the system. Note: Main and
spare lights are never on simultaneously, so spare lamps is not necessary to include in calculating
total power.
