This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used
in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installa-
tion. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help.

CAUTION
It should be noted the installation, operation, testing and maintenance of
the CO1224T/CO1224TR is different than System Sensor conventional 4-wire
smoke detectors, such as the i3 Series. Below are specific installation require-
ments for the CO1224T/CO1224TR:
• Connect to a non-resettable power supply
• Connect to a non-fire zone: Per NFPA 720 section 9.6.7.2 the CO1224T/
CO1224TR shall not be connected to a zone that signals a fire condition
• Per NFPA 720 section 9.6.7, do not connect the CO1224T/CO1224TR on
a zone with other fire or intrusion initiating devices - i.e. do not connect
on the same zone as smoke detectors
• Wiring of the trouble relay is mandatory: Per UL Standard 2075 section
17.1.1 a detector shall send a trouble signal to the control panel upon an
open circuit, a ground fault, sensor removal or sensor end of life
• If wiring one CO1224T/CO1224TR per zone: Use 4 conductors
• If wiring multiple CO1224T/CO1224TR detectors per zone: Use 4 con-
ductors from panel to first CO1224T/CO1224TR, then use 6 conductors
from the second CO1224T/CO1224TR to other detectors on the zone
