AC Wire-in Combination Photoelectric
Carbon Monoxide & Smoke Alarm
Part Number 21007624
Model KN-COPE-I
Installation of Smoke Alarm
The combination alarm should be installed to comply with all local codes having jurisdiction in
your area, Article 760 of the National Electric Code, and NFPA 72. Make certain all alarms are
wired to a single, continuous (non-switched) power line, which is not protected by a ground fault
interrupter. A maximum of 1000 ft. of wire can be used in the interconnect system. Use standard
UL listed household wire (18 gauge or larger as required by local codes).
Architectural and Engineering
Specifications
The combination smoke and carbon monoxide alarm shall be Kidde Unit Number KN-COPE-I
(part number 900-0213) or approved equal. It shall be powered by 120VAC, 60Hz source with a
9V battery backup. The temperature operating range shall be between 40°F and 100°F (4°C and
38°C) and the humidity operating range shall be 5% - 85% relative humidity.
The unit shall incorporate a photoelectric smoke sensor with nominal sensitivity of 2.05%/ft. The
CO sensor shall be of a fuel cell design and shall meet the sensitivity requirements of Underwriters
Laboratories UL2034 Single and Multiple Station Carbon Monoxide Detectors. The unit shall qualify
for UL-approved wording on the package: “World’s Most Accurate Carbon Monoxide Alarm”*.
The combination alarm can be installed on the surface of any wall or ceiling following the UL/
NFPA/Manufacturer’s recommended placement guidelines. The alarm can be installed on any
standard single gang electrical box, up to a 4”octagon junction box. The electrical connection
(to the alarm) shall be made with a plug-in connector. The unit shall provide optional tamper
resistance that deters removal of the unit from the wall or ceiling. No additional pieces shall be
required to activate this feature.
A maximum of 24 Kidde devices can be interconnected in a multiple station arrangement. The
interconnect system must not exceed the NFPA (National Fire Protection Association) limit of 18
initiating devices, of which 12 can be smoke alarms. With 18 initiating devices (smoke, heat, CO,
etc), interconnected, it is still possible to interconnect 6 strobe lights and or relay modules.
The alarm shall include a test button that will electronically simulate the presence of smoke
and CO and cause the unit to go into both modes of alarm. This sequence tests the unit’s elec-
tronics to ensure proper operation. The CO sensor will not alarm to levels of CO below 30 ppm
and will alarm in the following time range when exposed to the corresponding levels of CO.
70ppmCOConcentration60–240minutes
150ppmCOConcentration10–50minutes
400ppmCOConcentration4–15minutes
The combination alarm shall have two methods of warning for danger: a piezoelectric horn that
is rated at 85 decibels at 10 feet and a voice warning that identifies the danger. For a CO inci-
dent, the horn will sound in the repetitive manner – four (4) fast beeps, a short pause, four (4)
fast beeps, a short pause. In between, the unit will announce “Warning Carbon Monoxide!” In a
Smoke incident, the horn will sound in the repetitive manner – three (3) beeps, a pause, three (3)
beeps, a pause. In between, the unit will announce “Fire! Fire!” The unit shall incorporate 2 LED’s.
A green LED will be steady on when AC power is present, flash every 30 seconds when in the

battery only mode, every 16 seconds to indicate alarm memory, and every 2 seconds to
indicate the Hush“ mode is active. A red LED will flash in unison with the sounder pat-
tern. The unit shall include the Smart Hush™ feature that silences the unit for approxi-
mately 8 minutes if a nuisance alarm condition occurs. The Green LED on the alarm will
flash every 2 seconds while in Smart Hush™ and will automatically reset itself. It also pro-
vides voice annunciation of “Hush Activated” when Smart Hush™ is activated and “Hush
Cancelled” when the Hush cycle ends.
The unit shall also indicate a low battery warning utilizing each of the following
methods: a brief alarm chirp, the voice announcement of “Low Battery!” The unit shall
at a minimum meet the requirements of UL 2034, UL217, NFPA72, (chapter 11 2002
edition) The State of California Fire Marshall, NFPA101 (One and two family dwellings)
Federal Housing Authority (FHA), Housing and Urban Development (HUD). It shall also
include a 7-year manufacturer’s limited warranty.
