Carbon monoxide alarm procedure
WARNING: The carbon monoxide (CO) alarm indicates the
presence of CO, which can kill you. If the alarm signal sounds
four times, pauses for five seconds, and then repeats the
pattern:
1. Move to fresh air immediately — outdoors or by an open
door or window. Check that all persons are accounted for.
Do not reenter the premises or move away from the open
door or window until emergency services responders have
arrived, the premises have been aired out, and your
detector remains in normal condition.
2. Call emergency services, the fire department, or 911:

Information about carbon monoxide
WARNINGS
•Read these installation instructions in their entirety before
proceeding. Leave these instructions with the owner/user
of this CO detection equipment.
•This product is intended for use in indoor locations of
dwelling units. It is not designed to comply with
Occupational Safety and Health Administration (OSHA)
commercial or industrial standards.
•The detector only indicates the presence of CO gas at the
detector. Carbon monoxide gas may be present in other
areas.
•Failure to properly install, test, and maintain a CO detector
may cause it to fail, potentially resulting in loss of life.
•Installation of this detector is not a substitute for proper
installation, use, and maintenance of fossil fuel-burning
appliances, including appropriate ventilation and exhaust
systems.
•To reduce the risk of CO poisoning, test the detector
operation when not in use for 10 days or more.
•This detector does not operate without electrical power. As
fires frequently cause power interruption, discuss further
safeguards with the authority having jurisdiction (AHJ).
•Do not paint the detector.
Notes
•Regulatory code may require that the system generate a
three-pulse temporal code (TC3) for fire alarms and a four-
pulse temporal code (TC4) for CO alarms.
•The CO sensor is calibrated at the factory. CO sensitivity
is set to conform to UL 2034 requirements and cannot be
changed by the user. See “Regulatory information” on
page 4 for specific sensitivity values.
•Connect this detector only to a UL Listed control panel
capable of differentiating between alarm signals (fire,
burglary, CO, etc.) and providing distinct identification for
each.
•To reduce the likelihood of nuisance alarms, ventilate
accommodation spaces when using household cleaning
supplies or similar contaminants. If a detector has been
exposed to such contaminants, test it promptly afterwards.
Symptoms of CO poisoning
The following symptoms related to CO poisoning should be
discussed with all occupants of the protected site.
Mild exposure: Slight headache, nausea, vomiting, fatigue,
runny nose, sore eyes (often described as "flu-like" symptoms).
Medium exposure: Severe throbbing headache, dizziness,
drowsiness, confusion, fast heart rate.
Extreme exposure: Unconsciousness, brain damage,
convulsions, cardiorespiratory failure, death.
Many cases of reported CO poisoning indicate that while
victims are aware they are not well, they become so
disoriented that they are unable to save themselves by either
exiting the building or calling for assistance. Young children
and pets may be the first affected.

2 / 4 P/N 3102074-EN • REV 02 • ISS 09MAY13
CO sources
The CO sensor in this detector is designed to detect carbon
monoxide gas from any source of combustion. It is not
intended to detect fire, smoke, or any other gas. Potential CO
sources include fuel-fired appliances (e.g., space heater,
furnace, water heater, range, oven, clothes dryer); other
sources of combustion (e.g., kerosene-burning stove or heater,
or gas log fireplace); or internal combustion engines.
In addition, excessive exhaust spillage or reverse venting of
fuel-burning appliances can produce dangerous transient
levels of CO. This can be caused by external conditions:
•Wind direction, velocity, or a combination of both,
including high gusts of wind or insufficient draft in vent
pipes
•Temperature inversions that can trap exhaust gases near
the ground
•Negative pressure differential resulting from the use of
exhaust fans
•Simultaneous operation of several fuel-burning appliances
competing for limited internal air
•Vent pipe connections vibrating loose from dryers,
furnaces, or water heaters
•Obstructions in vent pipes or unconventional vent pipe
designs which can amplify the above situations
•Poorly designed or maintained chimneys and/or vents
•Extended operation of unvented fossil fuel-burning devices
(range, oven, fireplace, etc.)
•Idling cars in an open or closed attached garage, or near
the premises
General limitations of CO detectors
This detector is designed to protect individuals from the acute
effects of CO exposure. It will not fully safeguard individuals
with specific medical conditions. People with special medical
problems should consider using specialized detection devices
with less than 30 ppm (parts per million) alarming capabilities.
If in doubt, consult a medical practitioner.
If the unit is in trouble or at the end of its life, it may not sense
CO and cannot be relied upon to monitor CO levels. Replace
the CO module every six years from the date of manufacture or
when the control panel indicates a sensor end-of-life condition,
whichever comes first.
A detector installed outside a bedroom may not awaken a
sleeper. Normal noise due to stereos, television, etc. may also
prevent the detector from being heard if distance or closed or
partly closed doors muffle the sounder. This unit is not
designed for the hearing impaired.
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 1 shows appropriate detector locations.
Install detectors according to applicable codes and standards.
Place wall-mounted detectors at least 5 ft. (1.5 m) up from the
floor. For ceiling mounted applications, place detectors at least
1 ft. (0.3 m) from any wall. 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

Description
The model V-PCOS Intelligent Photoelectric Smoke Detector
with CO Sensor is an intelligent device that uses an optical
sensing chamber to detect smoke, and a CO sensor to detect
carbon monoxide from any source of combustion. The detector
analyzes the smoke and CO sensors independently to
determine whether to initiate a fire alarm, a life safety CO
alarm, or both.

LED indicator. The LED indicator (see Figure 2) displays the
following states:
•Normal: Green LED indicator flashes, no action.
•Alarm/active: Red LED indicator flashes, evacuate the
area.
•Stand-alone alarm: Red LED indicator turns on, evacuate
the area.
Sensor end-of-life indicator. The detector signals a
"COMMON TRBL ACT" condition on the control panel when
the CO sensor reaches its end of life. Pressing the Details
button on the control panel displays "END OF LIFE ACT"
providing verification that it is an end-of-life trouble of the CO
sensor. This trouble remains active until the sensor is replaced,
even if the panel is reset. See “Replacements” on page 4.

Installation
Notes
•This detector does not sense fires in areas where smoke
cannot reach the detector. Smoke from fires in walls,
roofs, or on the opposite side of closed doors may not
reach the detector.
•This detector does not detect oxygen levels or flames. Use
this device as part of a broad-based life safety program
which includes a variety of information sources pertaining
to heat and smoke levels, extinguishment systems, visual
and audible devices, and other safety measures.
•Photoelectric detectors have a wide range of fire-sensing
capabilities and are best suited for detecting slow,
smoldering fires.
•To ensure proper operation, store the detector within the
recommended ranges. Allow the detector to stabilize to
room temperature before applying power.
•The dust cover (supplied) must remain on the detector
during installation and be removed prior to commissioning
and service. The dust cover is not a substitute for
removing the detector during new construction or heavy
remodeling.
•Do not install detectors until after final construction
cleanup (unless otherwise specified by the AHJ).
•Do not use smoke detectors with detector guards unless
the combination has been evaluated and found suitable.
•Install per NFPA 72 National Fire Alarm and Signaling
Code, NFPA 720 Standard for the Installation of Carbon
Monoxide (CO) Detection and Warning Equipment, and
UL 2075 Standard for Gas and Vapor Detectors and
Sensors.
•Upon completion of the original installation and following
any modifications or additions to the system, perform a
calibrated sensitivity test per NFPA code. The Signature
Series can perform this test and generate a system
sensitivity report.
•To permanently disable the tamper-resist mechanism prior
to placing the detector in difficult to reach locations, break
and remove the plastic lever arm from the base. See
Figure 2.
To install the detector:
1. Install and wire the base, as described on the installation
sheet supplied with the base.
2. Remove the serial number label from the detector and
