How to test alarm functions of the lights

①Connect the lamp to the power supply（using 3*1.5 cable）AC85-265V/DC20V-60V

② After power on, check whether Lamp1and Lamp2 are working or not or whether the

indicators (System good indicator) on the PCB board is on or not

③The lamp have two operation modes: “service+service” or “service+standby”(when the

dip switch is “ON” position, the lamp is “service+service” mode; when the dip switch is

“service+standby”). When the lamp is in the “service+standby” operation mode, if Lamp

1 fails, after 30s, COM/NO 1 will give an alarm, and will switch to the Lamp 2 automatically,

Alarm 1 indication will be off, and System good indication will flash. Similarly, when the Lamp

2 fails, after 30s, Alarm 2 indicator will be off and COM/NO 2 will give an alarm.

When the lamp is in the “service+service” operation mode, if any of the lamp fails, after

30s,COM/NO1,COM/NO2 will give an alarm, Alarm1and Alarm2 indication will be off，System

good indication will flash.

④All the lamps will be switched off after photocell working, COM/NO1,COM/NO2 will give an

alarm and system good indicator will flash(Note: Lamp work indicator will be off). When the

lamp is in steady burning operation mode, lamp work indication will be steady burning; when

the lamp is in flashing operation mode, lamp work indicator will be flashing.

⑤If the main power supply fails, COM/NO1,COM/NO2 will give an alarm.
