CO detectors are not a substitute for life safety. Though these
detectors will warn against increasing CO levels, we do not warrant or
imply in any way that they will protect lives from CO poisoning. They
should only be considered as an integral part of a comprehensive
safety program.
Detector locations
Selecting a suitable location is critical to the operation of CO detectors.
Figure 2 shows appropriate detector locations.
Verify the detector is installed in accordance with all applicable
governing laws, codes, or standards. For combination detectors, follow
the spacing requirements for each sensor. Refer to the control panel’s
application bulletin for the sensor spacing requirements.
The recommended CO detector locations are:
•
Outside each separate sleeping area in the immediate vicinity of
the bedrooms (including areas such as hotel rooms and dorm
rooms)
•
On every occupiable level of a dwelling unit, including basements,
but excluding attics and crawl spaces
•
Centrally located on every habitable level of the building and in
every HVAC zone based on an engineering evaluation considering
potential sources and migration of carbon monoxide
•
On the ceiling in the same room as permanently installed fuel-
burning appliances
•
In any area required by local building codes, legislation, or the AHJ
•
In a suitable environment per the detector specifications (see
“Specifications” on page 4 for details)
•
On a firm, permanent surface
Do not install the CO detector:
•
Within 5 ft. (1.5 m) of any cooking appliance
•
Within 10 ft. (3 m) of a fuel-burning appliance
•
Near air conditioners, heating registers, or any other ventilation
source that may interfere with CO gas entering the detector
•
Where furniture or draperies may obstruct the airflow
•
In a recessed area

Testing
Before testing, notify the proper authorities that the fire alarm system is
undergoing maintenance and will be temporarily out of service.
Test each sensor in the detector.
Caution:
Heat damage. Excessive heat may damage the detector
outer cover. Do not apply excessive heat when using a hair dryer.
When using a Testifire detector tester, you must install a SIGA2
Testifire Adapter Assembly.
Make sure the SIGA2 Testifire Adapter Assembly (model
SIGA2-TSTSPACER) is installed in the Testifire detector tester before
testing. Refer to the
SIGA2 Testifire Adapter Assembly Installation
Sheet
(P/N 3101942-ML) for further details.
Note:
If the CO sensor is programmed as an alarm point, it must
comply with the requirements of NFPA 720.
To perform an initial installation test:
1. Visually
inspect
each
detector and verify that it is installed in the
correct location. Make sure that factors not apparent on the plans
do not adversely affect the detector.
2. Remove the detector from its base and verify that the proper
detector address, trouble signals, and messages are reported.
3. If wired for Class A operation, verify that the detector continues to
operate first with SLC_IN disconnected, and then with SLC_OUT
disconnected. (Refer to the installation sheet for the base.)
4. Place a momentary ground fault on the SLC circuit to verify
operation of ground fault detection circuitry.
5. Run a system detector sensitivity report on all detectors and verify
that readings fall within acceptable limits.
6. Perform a sensor function test, as described below.
To perform CO sensor function tests:
1. Use the fire alarm control panel to put the detector into accelerated
response mode. (Refer to the panel technical reference manual for
instructions.)
2. Activate the CO sensor using SDI LLC model Solo C6 CO aerosol
spray without covering the head, or using the Testifire detector
tester per the manufacturer’s instructions.
To perform non-CO sensor function tests:
1. If desired, use the fire alarm control panel to put the detector or
zone into a service group for testing. (Refer to the panel technical
reference manual for instructions.)
2. Activate the smoke sensor using No Climb Products model Smoke
Centurion/M8, FireTech Smoke or Smoke Sabre smoke aerosol
spray, a smoke generator, or the Testifire detector tester per the
manufacturer’s instructions.
3. Activate the heat sensor using a hair dryer (maintaining a distance
of three inches) or using a Testifire detector tester per the
manufacturer’s instructions.
Maintenance
To ensure proper operation, plan maintenance (regular or selected) of
the detector in accordance with the AHJ and all applicable governing
laws, codes, or standards. Refer to NFPA 72
National Fire Alarm and
Signaling Code.
NFPA 720
Standard for the Installation of Carbon
Monoxide(CO) Detection and Warning Equipment
.
Refer to application bulletin P/N 3102650-EN for additional information
and cleaning instructions.
CO sensor.
The CO sensor has a 10 years life from the date of
manufacture or when the control panel indicates a sensor end-of-life
condition, whichever comes first.
