Other uses in PROBE FAULT mode:
The cycling of the sounders can be used to set CT-A1 exit delay time (see page 9 ), annunciator
duration (see page 10), and re-trigger hold-off time (see page 10). It may also be used to check all of
the sounders without the need for a vehicle tripping the system.

The SD-6 is a dual-probe set that works with the CF-2C and differs from the CT-6 in that it can be
as close as 10 feet to outside cross traffic. Only one SD-6 system can be used with a CF-2C control
unit. For installation instructions, please refer to the manual accompanying the SD-6 dual-probe
system.

See Figure 2 on page 2. The CF-2C is engineered to accept other sensing devices in conjunction
with or exclusive of the CT-6 probe. You may use as many and as varied sensing devices as you
like. To do so, you will need the following:
1. A sensing device with a normally open, floating, dry relay contact
2. A 500 - 1000 ohm resistor
To connect your sensing device to the CF-2C, attach one side of the device to terminal 17, the
other side to terminal 19 and place a 500 - 1000 ohm resistor across those two terminals.

See Figure 2 on page 2. The FC-6 photocell is designed to be mounted on a window pane with its
"eye" looking outside. Its distance from the control unit is not important.
To insure good adhesion, clean the window area with alcohol. Peel off the double-sided tape cover
paper and mount the photocell on the window. The hole on the sticky side of the photocell should be
at the top, and the screw terminals situated so that the wires will be connected from the top.
Using a 2-wire, shielded cable, connect the two primary wires to the screw terminal on the
photocell. The shield drain wire does not connect to anything on the photocell. Cut it off there.
At the CF-2C control unit, connect the SHIELD drain wire to terminal No. 16, and the two primary
wires to terminals No. 7 and 15 (see Figure 2 on page 2).
Note: Static discharge from lightning can damage the photocell. It is therefore important to use
shielded cable for photocell hook up.
SPECIAL NOTE
The FC-6 and FC-12 photocells are manufactured by Cartell and function as a light
sensitive resistor. Measuring with an ohm meter, the resistance generally will be in the 2000 to 5000
ohm range in full sunlight. As the light diminishes, the resistance instantly goes up. The CF-2C
floodlight timer circuit is locked out when the resistance is below 1 mg-ohm. When measuring the
resistance between the two leads going to the photocell, if the resistance does not vary with a change in
light level, the photocell may have been damaged by lightning; if it is shorted or open, there may be wire
damage. A lightning damaged photocell or a shorted wire will keep the CF-2C lights from coming on at
night. An open wire to the photocell will allow the lights to come on day and night.

MOUNTING
Install sounders in a single-gang electric box for flush mounting.
WIRE
Use CAT-5 wire. To avoid corrosion, solder-tin the ends of the wires before connecting to the
sounder and control unit . Always connect the wire to the sounder first and then to the control unit.
