4. Installing the Alarm
• These are mains powered alarms, so isolate the mains supply before commencing
installation. They are for installation by a qualified electrician in accor-
dance with the current I.E.E. regulations (See section 7 if interconnecting
additional alarms).
• Select suitable location having regard to earlier advice.
• Bring house wiring through a dry lining box or Kidde surface pattress, (SMK 23)
into terminal block (not included).
• If wall mounting,connect supply through a 3 amp fused spur into Kidde surface
pattress SMK 23.
• Site the alarm at least 1.5m above the floor. When sited in same room as an
appliance, the alarm should be sited at a horizontal distance between 1m and
3m from the appliance. In rooms with no appliance, site approximately at face
level; in the lounge this would be at face level when seated; in the bedroom it
would be at face level whenever you lie down.
• The appropriate power source is 230VAC
power supply from a non-switchable cir-
cuit, which is not protected by a ground
fault interupter.

: Do not use any other type of rechargeable battery in your alarm or attempt to
recharge the battery pack yourself. Improper charging may even cause the battery pack
to overheat or leak, thus posing possible injury to the user. The Lithium-Ion battery is to
supply short term backup during a power cut.
Do not attempt to replace the battery as the alarm has no user serviceable parts.
Opening the alarm will invalidate the guarantee and could expose you to live parts.
(DIgital model only),During the first 10-hour initial charge period or,until the battery has charged,
"Lb" will be displayed along with the CO level (usually "0") and without an audible "chirp".
When the initial charge is complete,the "Lb" will disappear. If however,after 10 hours the battery
is not charging properly, "Lb" may continue to flashAND there will be an audible "chirp" once
every 15 seconds indicating the battery is not charging.
The unit will notify you of a battery error condition by flashing the red SERVICE LED,
amber Low Battery LED, and beeping once every 15 seconds (and on the Digital model
displaying “Lb”).
If this happens, the battery is discharged or has been
damaged. Ensure switch on back of unit is ON.
Ensure thatAC power is being supplied to the unit.If the
unit has been withoutAC power,the battery voltage will
be low and needs to be recharged.Turn the AC power on
and the battery will automatically re-charge. Note,a
discharged battery will require approximately 24 hours to
fully charge and provide the maximum protection while
on battery-back-up.
IfAC power is ON, and after 10 hours the red SERVICE LED and amber Low Battery LED
are still flashing, contact your Installer,landlord or Kidde Fyrnetics.
6. Initial Checking and Testing of Alarm
•Having energised circuit, press and release the test button – the alarm should sound
and other interconnected ones also, within a few seconds.
• Do this for all alarms.
• If any do not sound, isolate mains and recheck cabling.
• Advise the house-holder as to how to test the alarms, referring to enclosed
Operator Manual.
• Do not reconnect alarm toAC power with battery switch in“Off” position as unit
will beep every 15 seconds to alert you of flat/missing battery.
4. Installing the Alarm

5
• This CO alarm can be used independently or interconnected up to 17 Kidde
Fyrnetics AC smoke, heat or CO alarms. i.e. 18 in total, as listed below.
• Crossing line and neutral connections or line and interconnect connections will
fatally damage all interconnected alarms invalidating the guarantee.
• All interconnected alarms must be powered off the same fuse/circuit breaker.

8. Interconnecting with Kidde CO, Smoke and Heat
Alarms
When compatible Kidde smoke alarms and heat alarms are interconnected to your CO
alarm, they will only respond to a smoke or heat related event.
When mixing Kidde alarms which have battery back-up with models without battery
back-up, be advised that the models without battery back-up will not function during
an A.C. power failure.
Testing
When pressing theTest/Reset button, if the unit is operating properly, the red LED
will flash and you will then hear a series of quick beeps for 4 seconds, followed by
1/2 second of silence, followed by another series of quick beeps. Models with digital
display will show and then show a number (usually around 200) for several
seconds. After internal testing is complete, will be displayed and the alarm
will begin monitoring of carbon monoxide
If interconnected to Kidde Fyrnetics Smoke/Heat alarms, pressing theTest/Reset but-
ton on the CO alarm will have no effect on the Smoke/Heat alarms.The Smoke/Heat
alarms will not be tested and will not alarm. However, when pressing theTest button
on an interconnected Smoke/Heat alarm, the CO alarm will emit a Smoke/Fire audible
and visual alarm pattern of 3 long beeps, 1 second of silence, repeated. Note:You do
not need to press theTest button to take a CO reading.
Smoke/Heat Alarm Indicator
When an interconnected Kidde Fyrnetics smoke alarm detects smoke,or a heat alarm
detects 57oC, this unit will sound an alarm pattern of 3 long beeps, followed by a 1
second silence.This cycle repeats as long as smoke signal persists to alert you of the
condition. In addition on digital display models the word "FirE" will scroll across the
digital display. If this happens, leave the premises immediately by your escape plan
and call the emergency services.
WARNING: This unit is not a smoke alarm and will not detect smoke or fire.The
digital model will only display "FirE" and alarm for Smoke/Fire if it receives a signal
from an interconnected Kidde Fyrnetics Smoke/Heat alarm.
Note: A smoke/heat alarm situation will override a CO alarm condition .
Refer to Operator’s Manual for additional instructions on testing the alarms.

9. Timing of Installing
New Build
• Install the base plate (and surface pattress if used) at first fix.
• Do not install alarm itself until following trades have finished e.g. plasterers, painters,
carpet fitters, etc.
• Do not install if property remains damp or unheated.
• Dust and other contaminants e.g. paint fumes, will enter the alarm causing possible
nuisance alarms and damage the sensitive components within (it will also invalidate
the guarantee provisions).
•Never plug in or remove cabling when circuit is live as you could short circuit it and
invalidate the guarantee.
• After installation, cover the alarm with the supplied dust cover – this must be
removed just prior to occupation for the alarm to function.
11. Ongoing Maintenance
CAUTION: This unit is sealed. The cover is not removable.
• Test the alarm once a week by pressing the Test/Reset button.
• Vacuum the alarm cover and wipe with a cloth once a month to remove accumulated
dust.
• Never use detergents or solvents to clean the alarm. Chemicals can permanently
damage or temporarily contaminate the sensor.
• Avoid spraying air freshener, hair spray, paint or other aerosols near the alarm.
The following is a list of substances that at high levels can damage the sensor or cause
temporary readings on the digital display that are not carbon monoxide readings:
Ethylene, ethanol, alcohol, iso-propanol, benzene, tolulene, ethyl acetate, hydrogen,
hydrogen sulfide, sulfur dioxides, most aerosol sprays, alcohol based products, paints,
thinners, solvents, adhesives, hair sprays, after shaves, perfumes, auto fumes (cold
start), and some cleaning agents.
10. Decorating
• Never paint the alarm.
• During redecoration, all alarms should be removed from the area to prevent contami-
nation of the sensor by fumes.(Fumes can permanently damage the alarm).
Do not install or replace the alarm until the surrounding paintwork is thorough-
ly dried and there are no paint fumes present.
• Whilst covered, the alarm cannot operate. Remove covering as detailed above.
12. Repair/Servicing
If the alarm is not functioning, first check the troubleshooting section.
If this does not rectify the problem:
• Ensure that the green L.E.D. is lit.
•If within guarantee, contact your installer or landlord, or return postage paid to the
address at the end of this manual, with a copy of the invoice or proof of date of
installation.
• There are no user serviceable parts.
Opening/interfering with alarm, invalidates the guarantee.

13. Limitations of CO Alarms
• This alarm will only indicate the presence of CO at the sensor.
• CO may be present elsewhere in the property.
• All alarms must be tested regularly to make sure the back up batteries and the alarm
circuits are in good operating condition.
• CO alarms cannot provide an alarm if the CO does not reach the unit.
• Therefore, they may not sense CO on the other side of a closed door or on a
different floor. If the alarm is located outside the bedroom or on a different floor, it
may not wake up a sound sleeper.
• The use of alcohol or drugs may also impair ones ability to hear the alarm.
• For maximum protection a CO alarm should be installed in each sleeping area and
on every level of a home. Hearing impaired occupiers should consider fitting addi-
tional strobe accessories to give a visual alarm.
• CO Alarms are not a substitute for annual routine servicing of appliances by a quali-
fied installer.
