Hardwired Smoke & Carbon Monoxide Alarm
Model 900-CUAR
Installation of 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).
Industry experts recommend specific locations for smoke alarms, such as
every level and sleeping area of the dwelling. They also recommend a CO
alarm be installed on each level of the home – ideally on any level with fuel
burning appliances and outside of sleeping areas. See User Guide for further
information.
Architectural and Engineering
Specifications
The combination smoke and carbon monoxide alarm shall be Kidde Model
900-CUAR or approved equal. It shall be powered by 120VAC, 60Hz source
with two (2) AA backup batteries. The temperature operating range shall be
between 40°F and 100°F (4.4°C and 37.8°C) and the humidity operating range
shall be 10% - 95% relative humidity, non-condensing.
The unit shall incorporate a photoelectric smoke sensor with nominal
sensitivity of 1.74 +/- 0.78 %/ft OBS. The CO sensor shall be of an
electrochemical design and shall meet the sensitivity requirements of
Underwriters Laboratories UL 2034 Single and Multiple Station Carbon
Monoxide Alarms. 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.
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. This alarm is not designed to be interconnected with other
manufacturer’s products, unless otherwise specified.
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 electronics 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.
70 ppm CO Concentration: 60 – 240 minutes
150 ppm CO Concentration: 10 – 50 minutes
400 ppm CO Concentration: 4 – 15 minutes
The combination alarm shall warn of danger using a piezoelectric horn that
is rated at 85 decibels at 10 feet. For a CO incident, the horn will sound in
the repetitive manner – four (4) fast beeps, a short pause, four (4) fast beeps.
In a Smoke incident, the horn will sound in the repetitive manner – three (3)
beeps, a pause, three (3) beeps. The unit shall incorporate four (4) LEDs. A
green LED will be steady on when AC power is present, or flash every 60
seconds when in the battery only mode. A red LED will flash once or twice
every 15 seconds to indicate smoke or CO alarm memory, and will flash in
unison with the sounder pattern. An amber LED indicates fault conditions.
The unit shall include the Hush
TM
feature that silences a smoke alarm for
approximately 8-10 minutes if a nuisance alarm condition occurs. The red
LED on the alarm will flash every 2 seconds while in Hush
TM
and the unit will
automatically reset itself.
The unit shall also indicate a low battery warning utilizing a brief alarm
chirp. The unit shall at a minimum meet the appropriate requirements of UL
2034, UL 217, NFPA 72, The State of California Fire Marshal, NFPA 101 (One
and two family dwellings), Federal Housing Authority (FHA), Housing and
Urban Development (HUD). It shall also include a 10-year manufacturer’s
limited warranty.
WARNING:
This product is intended for use in indoor residential locations. It is not
designed to measure compliance with Occupational Safety and Health Administration
(OSHA) commercial or industrial standards. This device is designed to help protect
individuals from acute effects of Carbon Monoxide exposure. It will not fully safeguard
individuals with specific medical conditions. If in doubt, consult a medical practitioner.
Individuals with medical problems may consider using warning devices which provide
audible and visual signals for carbon monoxide concentrations under 30 ppm.
