Photocell switch
Photocell switch is a built-in device for automatic on/off switching of IR-1 illuminator, with operating threshold light level of 3
lux. From short-term changes in lighting, such as headlights of a passing car, photocell is protected by a turn on delay chip, that shuts
down power if light stays on for over 30 sec.
To manually de-activate the photocell switch:
– un-screw four back panel screws;
– carefully remove the back panel;
do not damage the wire connecting power board to a photo sensor;
do not let the radiator out of the case
– pull JP1 jumper out of the power board.
– carefully screw the back panel back in
CONDUCT ALL OPERATIONS WITH PHOTOCELL SWITCH ONLY AFTER IR-1 IS POWERED DOWN!!!
