Honeywell XC70, XC100D, XC100 Operating And Installation Instructions

1. Welcome

Thank you for purchasing this Carbon Monoxide (CO) alarm.

The symbols above mean that the alarm is suitable for use in
domestic premises (including static caravan holiday homes),
caravans, motor caravans and boats.

This manual contains important safety information about the
installation and operation of the alarm. Read the manual carefully
and keep it in a safe place for future reference.

Honeywell offers three versions of its battery powered CO alarms,
with different user interfaces and lifetime:

The basic model XC70 uses indicator lights to visually signal the
state of the unit and comes with 7 years life and warranty

XC100 and XC100D both show big alarm messages in the case of

an alarm, and both come with 10 years life and warranty.

XC100D has an LCD screen to provide more information about

rising CO levels and recorded CO peak levels.

In addition, all versions have an audible alarm and a TEST/HUSH
button.

All Honeywell X-Series alarms can be wirelessly interconnected
using an optional plug-in module. This means that if one X-Series
CO or Fire Alarm triggers an alarm, all interconnected units will
give an audible alarm as well. This is especially useful, when
living in a large or multi-story dwelling. Some wireless module
information is included in this manual for completeness.

Warnings

Installation of a CO alarm should not be used as a substitute
for proper installation, use and maintenance of fuel burning
appliances including appropriate ventilation and exhaust
systems.

This CO alarm is designed to protect individuals from the
acute effects of carbon monoxide exposure. It will not fully
safeguard individuals with specific medical conditions. If in
doubt consult a medical practitioner.

Long exposure to low levels (>10 ppm) of CO may cause
chronic effects. If in doubt consult a medical practitioner.

4. CO Alarm Operation continued

4. CO Alarm Operation

Normal operation

The green POWER light will ash once per minute, to indicate that
your alarm is working. The screen of the XC100D will be blank.

Alarm

If a dangerous CO condition is detected the red ALARM light/

message will ash and the audible alarm will sound continuously.

XC100D will display the current CO level and a skull symbol.

If the unit is in ALARM and the gas clears, the unit will go into
Alarm Memory mode. Press the TEST/HUSH button to return to
normal operation.

If your unit is in ALARM, keep calm, and carry out the
following actions in the order given:

• Open all doors and windows to increase the rate of
ventilation

• Stop using all fuel-burning appliances and turn them off
where possible

• If the alarm continues, then evacuate the premises. Leave
the doors and windows open, and only re-enter the building
when the alarm has stopped

• Get medical help for anyone suffering the effects of
Carbon Monoxide poisoning, such as headache or nausea,
and advise that Carbon Monoxide inhalation is suspected

• Telephone the gas or other fuel supplier on their emergency
number, so that the source of carbon monoxide emissions

can be identied and corrected

• Do not use the fuel-burning appliances again until they
have been checked and cleared for use by a competent
person according to national regulations

Note: There may be another source of carbon monoxide
emission apart from fuel-burning appliances, for example a
large amount of tobacco smoke, town gas or emission from a

smouldering re.

The CO alarm will activate if it has detected a certain
concentration for a given time, as described below:

50 ppm: Alarm between 60 and 90 minutes
100 ppm: Alarm between 10 and 40 minutes
300 ppm: Alarm within 3 minutes

The CO alarm is set in accordance with the relevant European
standard to provide alarms that are determined by the
concentration and how long it has been present. This ensures
that the alarm activates when dangerous levels of CO have built
up over time and immediate action is required, and avoids false
alarms from temporary low levels of CO (e.g. from cigarette
smoke).

4. CO Alarm Operation continued

If the unit is in ALARM, the audible alarm can be silenced for
5 minutes by pressing the TEST/HUSH button (the red light will

continue to ash, XC100D will show the muted symbol). If a

dangerous gas level is still present after 5 minutes, the audible
alarm will sound again.

Note: The HUSH function only operates if the gas reading is less
than 350 ppm and can only be operated once

Alarm memory

CO does not leave any detectable traces, so if an alarm happens
while you are out, the memory function will keep the red light

ashing till the button is pressed or 7 days have passed.

XC100D will also show the recorded peak concentration level for

10 seconds after pressing the button.

Event logger

Honeywell’s CO alarms record a history of events, which can
be downloaded by professionals. This provides a more in depth
analysis of CO events such as detailed information on the CO
concentration of the last 7 days, and weekly maximums for the
whole operating life. Dates of alarm events are recorded.

All alarms have four status indicator lights, an audible alarm and a

TEST/HUSH button.

The green POWER light indicates that the unit is activated and
working normally.

The red ALARM light indicates that a dangerous CO condition has
been detected.

The blue VENTILATE light gives an early indication of a dangerous
CO condition.

The yellow FAULT light indicates that the unit is not working
properly.

The TEST/HUSH button is used to test the unit, or to mute an alarm
or fault signal.

Ventilate - Pre-Alarm

Dangerous CO levels may be caused by faulty appliances, which
start to produce more and more CO over time. Pre-alarms will give
an early warning of such situations even if the alarm levels are
not being reached. If these occur frequently it is recommended
to call a technician for further investigations. The pre-alarm will
start giving indications once 25% of the alarm level (time and
concentration) has been reached. For example, if 50 ppm CO is
present, the pre-alarm will start after 15-23 minutes instead of
60-90 minutes for a full alarm.

By default, this function is deactivated as it is not required to
protect you from dangerous levels of CO. The installation section
gives details of how to activate it. The pre-alarm is intended to
help the knowledgeable end-user to get an early indication of
malfunctioning appliances.

If the Pre-Alarm function is activated, and CO is detected, the blue

ventilate light will ash with a short chirp 1, 2 or 3 times every 30

seconds when 25%, 50% or 75% of the alarm level respectively
has been reached. XC100D will also indicate the percentage of the
alarm level and current CO concentration. The audible alarm can
be silenced by pressing the TEST/HUSH button (XC100D will show
the muted symbol).

Fault – end of unit life

If the unit is in FAULT the YELLOW light will ash every minute
with a short chirp. The CO alarm must not be used any more,
and should be replaced. (The only exception is a wireless module
fault, which is signalled with a triple chirp. In this case, refer to
the wireless module manual for further details). The chirps can
be silenced for 24 hours by pressing the TEST/HUSH button.
The 24 hour period can be restarted by pressing the TEST/HUSH
button twice (XC100D will show the muted symbol).

Note: The fault signal is caused by a low battery, an electronics
failure or the end of the CO sensor life. The end-of-life signal
comes from an inbuilt timer, and is given 10 years (XC100,
XC100D models) or 7 years (XC70 model) after activation.

A replace by date is also printed on the side of the unit to
facilitate an advance replacement before the end-of-life signal
is given. This date includes a 6 months shelf life, i.e. this is the
latest date the unit should be replaced. An end-of-life signal may
be given earlier.

XC70 XC100 XC100D

Carbon Monoxide (CO) is an invisible, odourless gas which is
highly toxic. It is produced by the incomplete burning of fuels such

as wood, charcoal, coal, heating oil, parafn, petrol, natural gas,

propane, butane etc. and by cigarette smoke. A dangerous level of

CO can occur if an appliance is faulty or badly maintained, if a ue

is blocked or if a room is inadequately ventilated.

The poisoning effect of breathing in CO depends on the
concentration (described in parts per million, ppm) and how long
you are exposed for.

Concentration Signs and Symptoms

~ 100 ppm

Slight headache, ushing of skin
(indenite exposure)

200 – 300 ppm

Headache (5 – 6 hour exposure)

400 – 600 ppm

Severe headache, weakness, dizziness,
nausea, vomiting (4 – 5 hour exposure)

1100 – 1500 ppm

Increased pulse and breathing rate,
syncope (fainting), coma, intermittent
seizures (4 – 5 hour exposure)

5000 – 10000 ppm

Weak pulse, depressed respiration /
respiratory failure, death (1 – 2 minutes

Ideally, an alarm should be tted in every room containing a
fuel-burning appliance. It is strongly recommended to also t

alarms in bedrooms, and in rooms where you spend a lot of time.

If the alarm is being tted in the same room as a fuel-burning

appliance:

• It should be located close to the ceiling and at a height greater
than the height of any door or window

• A ceiling mounted alarm should be at least 300 mm from any
wall, and a wall-mounted alarm should be at least 150 mm
from the ceiling. Note: Ensure that you can access the tamper
proof locking tab.

• The alarm should be at a horizontal distance of between 1 m
and 3 m from the nearest edge of the potential source

If the alarm is being tted in a room without a fuel-burning

appliance it should be located relatively close to the breathing
zone of the occupants.

For premises such as bedsits, caravans or boats where the
accommodation is a single living space incorporating the sleeping
area, the apparatus should be positioned as far from the cooking
appliances as possible but near to where the person sleeps.

Warning

The apparatus should be installed by a competent person.

The alarm is switched on by clipping it into place in the wall
mounting plate.

Caution: Even if your alarm is free standing, you must attach
the wall mounting plate.

1. Fit the alarm onto the wall mounting plate approximately
10 mm to the left of centre

2. Press rmly against the wall plate and slide the alarm to the
right

3. Tamper proof locking tab will click into place

4. All lights will ash in sequence and the sounder will chirp to
indicate that the alarm has been activated.

5. The green light will blink once per minute indicating that the
alarm is operating

6. Test the alarm following the procedure for the Monthly Test.

The CO Alarm is certied by BSI to the European standard

EN 50291-1 “Electrical apparatus for the detection of carbon
monoxide in domestic premises” and EN50291-2 “Electrical

apparatus for continuous operation in a xed installation in

recreational vehicles and similar premises including recreational
craft”. It conforms to the Low Voltage Directive (LVD) and the

6. Testing your alarm

4. CO Alarm Operation continued

Low Level Monitoring Mode

Normally, the CO alarm only signals an Alarm condition after
a gas concentration higher than 43 ppm has been present for a
period of time. It can be temporarily set to a low level monitoring
mode, to enable it to be used as a measuring device. Once this
mode is activated, the alarm will signal the presence of a CO
level higher than 10 ppm immediately.

To activate the low level monitoring mode, press and hold the
test button for 18 seconds. (During this time, the low volume and
high volume tests will be active). After 18 seconds you will see a

green and a blue light ash and hear a short chirp and you can

release the button. The low level monitoring mode is now active

for 60 minutes, which is indicated by the ashing green light

every 4 seconds.

CO concentrations higher than 10 ppm will be indicated by
a ashing blue ventilate light. XC100D will also display the
CO concentration level.

The low level monitoring mode will end automatically after
60 minutes or by pressing the button at any time.
