Installation and Operation 1. Check whether the supply voltage complies with the rated voltage of the lamps. 2. Secure the light on the top of the tower or buildings using G3/4 pole and locking screw.

4 Installation and Operation 1. Check whether the supply voltage complies with the rated voltage of the lamps. 2. Secure the light on the top of the tower or buildings using G3/4 pole and locking screw. 3. Open the wiring compartment and terminate according to layout below and close front cover with screws. 4. Please note the earth terminal should be connected with the light fitting enclosure. ADJUSTMENT OF FLASHING RATE Isolate the power to the unit. DIP switches located within individual light fittings, undo screw and remove dome from light base. The circular circuit board will reveal the relevant DIP switches Please see below DIP switches for flashing rate and coding: 1=ON, 2=ON 1=OFF, 2=ON 1=ON, 2=OFF 1=OFF, 2=OFF 30FPM 40FPM 60FPM Steady Re-place front cover to base and tighten screws Energize lights, the light will work as your setting

5 DUAL LIGHT/TWO LIGHTS SWITCHOVER VAC: Isolate the power to the unit. DIP switches located within dual light base/junction box, undo screws and remove cover from light base. Please see below DIP switches for dual light or auto change-over coding: Power on, the light will work as per your setting. 1=OFF, 2=OFF:Light will operate in duty & stand-by configuration (Duty light ON + Standby light OFF). When and if duty light fails the standby light will switch on automatically. 1=ON, 2=OFF:Light will work in a double lamp configuration (Both lights ON at the same time). Note: Please use this product strictly on accordance with the instruction above
