OPERATION
With power applied, and a suitable load connected, the Cobra will be able to detect any moving infrared
source. The unit has a number of detection zones, at various vertical and horizontal angles.
The Cobra has two adjustments on the underside of the sensor head as shown on Fig1.

LUX
sensor. This adjustment can be set to allow the Cobra to operate the load at any light level between full
daylight and almost complete darkness.
The
TIME
adjustment can be set for any period between 10 seconds and 15 minutes. This is the time that
the lights will remain on after the last movement was detected. If movement is detected when lights were
already on, the timer automatically restarts.
LOCATION
achieved when the sensor is at a height of 2.5m.
Avoid positioning the sensor where there are any sources of heat in the detection zone. Such sources
cause false activation under extreme conditions.

OVERRIDE
To actuate the override function, switch the light switch on/off/on in quick succession. This will allow
the light to be operated as a standalone unit without the sensor switching.
