Introduction
Both of the Cartell control units can operate up to twelve
sounders. All our sounders mount in a single-gang
electrical box for flush mounting. All connections are
made to a screw terminal on the back of the sounder’s
circuit board. We suggest you use CAT-5 wire. Solder-tin
the ends of the wires before connecting to the sounder
and control unit to avoid corrosion. After you have run
cable from the control unit to the sounder, always connect
the wire to the sounder first and then to the control unit.
Note: After connecting wires to the sounder, and before
connecting the sounder to the control unit, measure
the resistance between the colored wire you choose to
connect to the sonalert and the colored wire you choose
to connect to ground. The resistance should never be
less than 75 ohms total. Resistance less than 75 ohms
shows damage to the wire between the control unit and
sounder (e.g., a staple through the wire) and will damage
the power supply.
CT-A1 Installation Instructions
Refer to the introduction above. First make the
connections at the CT-A1 plate and then to the control
unit as follows:
• Connect one colored wire to the terminal marked “G.”
At the control unit, test the resistance as noted above.
Then proceed to connect this wire to terminal 8 (CT-2B) or
to terminal 15 (CF-2C).
• Connect another colored wire to the terminal marked
“S” (for steady tone) or “P1” (for pulsating fast tone) or
“P2” (for pulsating slow tone). At the control unit, test the
resistance as noted above. Then proceed to connect this
wire to terminal 9 (CT-2B) or to terminal 14 (CF-2C).
• Connect a third colored wire to the terminal marked
“V.” At the control unit, this wire should be connected to
terminal 3 (CT-2B) or to terminal 5 (CF-2C).
If you are using a CF-2C control unit, three more
connections should be made:
• Connect a colored wire to the terminal marked “E” on
the CT-A1 to terminal 9 on the CF-2C.
• Connect a colored wire to the terminal marked “R” on
the CT-A1 to terminal 10 on the CF-2C.
• Connect a colored wire to the terminal marked “M” on
the CT-A1 to terminal 8 on the CF-2C.
CT-11 Installation Instructions
Refer to the introduction. First make the connections at
the CT-11 plate and then to the control unit as follows:
• Connect one colored wire to the terminal marked “−”. At
the control unit, test the resistance as noted above. Then
proceed to connect this wire to terminal 8 (CT-2B) or to
terminal 15 (CF-2C).
• Connect another colored wire to the terminal marked
“+”. At the control unit, test the resistance as noted above.
Then proceed to connect this wire to terminal 9 (CT-2B) or
to terminal 14 (CF-2C).
AA-1 Installation Instructions
The AA-1 works with any security or home automation
panel and with Cartell’s two control units (CT-2B and CF-
2C).
Refer to the introduction. First make the connections at
the AA-1 plate and then to the security (or other) panel.
The AA-1 requires two wires, one for power positive, the
other for power negative. Connect power positive from
security panel to the terminal marked SON on the AA-
1. Connect power negative from the security panel to
the terminal marked GND on the AA-1. Test resistance
positive to negative as described in the introduction and
finish by connecting wires to the security panel per the
installation instructions provided with said system.
When used with the Cartell control units, first make the
connections at the AA-1 plate and then to Cartell’s control
units as follows:
• Connect one colored wire to the terminal marked “GND”
on the AA-1. At the control unit, test the resistance as
noted in the introduction. Then proceed to connect this
wire to terminal 8 (CT-2B) or to terminal 15 (CF-2C).
• Connect another colored wire to the terminal marked
“SON” on the AA-1. At the control unit, test the resistance
as noted in the introduction. Then proceed to connect
this wire to terminal 9 (CT-2B) or to terminal 14 (CF-2C).
