See Figure 6 on page 10. The amount of time the floodlights remain on after the system is tripped
may be adjusted from 15 seconds to 15 minutes. The normal floodlight time is 5-10 minutes.
To set the floodlight time, remove the photocell wire from terminal No. 7. Push the TRIP-TEST
button. Measure from the moment the floodlight relay clicks on to the moment it clicks off. Adjust
potentiometer "B" (clockwise for time increase) and repeat until desired time is achieved. Reconnect
the photocell wire to terminal No. 7.

ENSITIVITY
See Figure 6 on page 10. Photocell sensitivity determines the level of outdoor light at which the
lights are allowed to come on. The factory sets the floodlights to come on at dusk.
To set the photocell sensitivity, make all adjustments at the precise moment when the amount of
daylight is visible at which time you want the floodlights to come on. Adjust potentiometer "D"
counter clockwise in very small increments and push the TRIP-TEST button after each adjustment
(see page 3). Stop adjusting at the point where the floodlight relay clicks on. The floodlights will be
allowed to turn on at that same daylight level from then on.

ENSITIVITY
See Figure 6 on page 10. Probe sensitivity is set at the factory and does not usually need to be
adjusted. Factory setting allows a single standard probe to cover a 12 foot wide driveway when
installed beside it (see "Installing CT-6 Probe and Cable" on page 5). Increasing the sensitivity
above the factory setting is not recommended unless the probe is located in a low sensitivity area.
When the probe is placed in the center of a driveway that is 18 feet wide or less, the sensitivity may
be decreased considerably, allowing the probe to be installed close to highway traffic or power lines.
To adjust probe sensitivity, turn the potentiometer "G" clockwise to increase, counter-clockwise to
decrease. A typical setting should be such that the CF-2C reliably detects a small car going 5 MPH.
You may increase sensitivity if necessary. Be aware, increasing sensitivity may cause false alarms.

UPPRESSOR
See Figure 6 on page 10. The factory setting for the transient suppressor circuit potentiometer "H"
is in the "on" position (fully clockwise). In this setting, short duration transient signals will be ignored.
With the circuit activated, false alarms from lightning will be reduced.
Note: if the probe sensitivity cannot be properly set as described in the "Adjusting Probe
Sensitivity" section (above), turn off the transient suppressor by adjusting potentiometer "H" fully
counter-clockwise.
