CO - The Housing Health & Safety
Rating System - the Landlords
The Housing Health and Safety Rating System (HHSRS) is the
new risk assessment procedure to replace the Housing Fitness
Regime and the Fitness Standard as an element of the Decent
Homes Standard. It came into force on 6th April
2006 in England and it will follow in Wales later in
the year. The HHSRS Operating Guidance
recognises that CO exposure can be a
significant hazard to occupants and states
that it is the landlords responsibility to assess
the risk of a CO leak in a property.
Scotland has a similar scheme to the
HHSRS in the Scottish Housing
Quality Standard.
House of Commons All Party
Parliamentary Gas Safety Group Shouting about a silent killer: Raising
CO awareness
Report as Published 14th September 2006
“We believe that there are ways of increasing the number of
reliable CO detectors in the home and would expect the
mortgage and insurance industries to find innovative ways to
ensure every home has one which is both audible and
approved to British Standard. There should be an expectation
that in order to complete a mortgage, or insure a property,
both CO and smoke detectors should be a requirement for all
What is CO & why does it need to
be monitored?
Carbon Monoxide is an invisible, odourless, tasteless and
extremely toxic gas that, if inhaled, can cause serious ill effects
- justifying its name as 'The Silent Killer'. CO is readily absorbed
by haemoglobin in the blood - approximately 240 times more
efficiently than oxygen. This causes serious damage to the
heart and brain from oxygen starvation.
How is CO produced?
Carbon Monoxide originates from the combustion of any
fossil fuel coal, bottled and natural gas, paraffin, wood, petrol, diesel,
charcoal etc.
What are the main sources of CO?
All Fossil fuel burning appliances produce CO, this is normally
vented through flues and chimneys to the outside atmosphere.
However, if the process is not entirely efficient, CO can build up to
dangerous levels. Examples of possible causes are:
Poorly connected, blocked, cracked or corroded
flue pipe/vent
Flue pipes/vents are designed to allow the CO produced by the
appliance to vent to the outside atmosphere. If the flue is not
operating correctly or is damaged, CO may leak into the
property. Even if there is an annual check on the appliance/s,
flues and vents remain a potential hazard.
Back drafting
Building Regulation requirements
for energy efficient homes and a
greater emphasis on air extraction
e.g. bathroom and kitchen fans,
means there is a risk of creating
negative air pressure. This can
cause reverse airflow through
appliances resulting in dangerous
levels of CO being drawn back
into the property.
Cracked heat exchanger on gas central heating
This will result in a large amount of CO leakage and is therefore a
particularly dangerous possibility.
Appliances without flues
Some fuel burning appliances do not have flues. Portable
heaters, cooking rings and grills are particularly vulnerable as are
old appliances. Whether burning liquid gas, paraffin, natural gas
or wood, each are capable of emitting dangerous levels of CO.

rbon Monoxide (CO) Alarms
What are the effects of CO poisoning?
Carbon Monoxide poisoning can have a very serious, even fatal,
effect on the body. Unfortunately, most people are unaware that a
relatively low level of CO exposure for a prolonged period can
have the same effect as a high level of CO exposure for a short
period. A major problem is that the symptoms of CO poisoning can
easily be confused with other common illnesses - such as cold and
flu. The table details the effects of cumulative CO exposure.
Is there any evidence of CO in
the home?
In January 2006, the Bartlett School of Graduate Studies at the
University College London, in partnership with Guys & St. Thomas
Hospital, carried out a survey into indoor CO exposure. It was
found that 18% of the homes monitored had CO levels that
exceeded the World Health Organisation (W.H.O.) guidelines.
32 Members of Parliament report to
the Government on the dangers of
CO poisoning
The publication of a report by the House of Commons All Party
Parliamentary Gas Safety Group (APPGSG) in September
2006 has once again raised serious questions concerning the
dangers of CO poisoning in the home. The report titled “Shouting
about a silent killer: Raising carbon monoxide awareness” looks
at all aspects of the dangers that CO can create and makes
proposals on what action should be taken to address these
issues. As the title suggests, the main focus is on raising awareness
of CO and its dangers with the general public, but it makes
some very pertinent comments for Landlords to take into serious
Excerpts from APPGSG Report 14th September 2006
• Too many people continue to be harmed or even killed as a
result of this entirely preventable problem.
• One death from CO poisoning is one too many.
• Improving CO detection by emergency workers and
increasing the number of reliable CO detectors in the home is
key to the fight to tackle CO poisoning incidents. Every home
should have a CO detector with an audible alarm. We call on
mortgage and insurance companies to investigate whether
requiring all homes to have such an alarm should be part of
granting a mortgage or insurance cover.

Calibration The Answer to Reliable Detection
Ei CO alarms made to exceed BS EN 50291: 2001 Precise and reliable calibration is now even more important
The BS EN 50291 British and European Standard for CO Alarms requires a much lower trigger level than the previous BS 7860, which it
supersedes. This is designed to give added protection to the more vulnerable members of society: the very young and the elderly.
However, this can mean that nuisance alarm from very low levels of CO can occur if the sensor is not very accurately calibrated. To
minimise this risk:
• Prior to alarm assembly every Ei CO sensor is independently calibrated at the factory in CO gas
• After alarm assembly every Ei CO Alarm is further tested in CO gas at the factory
These facts, coupled with sustained levels of quality throughout the manufacturing process ensure the very highest standard of
reliability and immunity from nuisance alarm.
Comprehensive Precision Calibration and Testing at 5 stages of the
Manufacturing Process
Sensors mounted on
bespoke calibration
circuits are loaded into
the CO enclosure, where
the CO gas exposure
program can be run.
As the CO gas exposure
program is run, the
sensors are subject to
precise CO levels for set
times with each sensor’s
individual response
being recorded by the
calibration circuitry.
Once recorded, the
sensors are loaded into
a custom interface to
extract data on each
individual sensor’s
The sensors are analysed
and are grouped
according to their
response. Each group is
then installed into a
specifically calibrated
circuit within the alarm,
ensuring that all alarms
accurately respond
when subjected to CO
Following assembly, all
finished alarms are
functionally checked for
response and accuracy

Time (minutes)
* When CO is inhaled, it combines with the
haemoglobin in the blood to form
Carboxyhaemoglobin (COHb). The CO displaces
the oxygen attached to the haemoglobin and as
such causes oxygen starvation throughout various
parts of the body.
BS EN 50291:2001 requires CO Alarms to trigger
before the %COHb in a typical user has risen
above approx 5 % COHb at low CO levels, such
as 50 ppm CO. At higher levels, such as 300 ppm
CO, the alarms must trigger before the level in a
typical user has risen above 2 %COHb. The effects
of COHb vary from one person to another,
people at most risk are the elderly, the very
young, pregnant women and those whose health
is already compromised. The adjacent chart
shows that the level of CO present over a period
of time increases the %COHb and that Ei CO
alarms respond well before a dangerous %COHb
level is reached. However, it should be noted that
people with heart disease and other associated
illnesses may suffer harmful effects even at low
COHb levels.
How do Ei CO Alarms Work?
Electrochemical Cell - Provides effective and responsive, long term detection
Carbon Monoxide enters the sensor through
a gas diffusion hole. A Graphite filter prevents
any external contaminants from entering. A
Platinum sensing electrode catalyses the
oxidation of the CO.
Combining with the water present in the
electrolyte, this reaction causes the voltage
to rise. Consequently, a small current flows
between the two electrodes.
This output is directly proportional to the
amount of CO gas present. The microchip in
the unit activates the horn/LED/display to
give a warning applicable to the CO level
Locating and Positioning CO Alarms
Where should CO Alarms
be located?
Where should CO Alarms be
BS EN 50292 the code of practice for the selection, installation,
use and maintenance of domestic CO alarms, recommends
the following location for CO Alarms:
Preferred position in rooms containing a fuel
burning appliance
• Install a CO Alarm in all rooms where there is a fuel burning
• If there is more than one appliance, but only one CO Alarm
is to be installed, the following priority list is recommended:
Rooms containing a flue-less or open-flued appliance
Rooms where occupants spend most time
Rooms in which the appliance is most used
If the dwelling is a bedsit the CO alarm should be
positioned away from the appliance, but close to the
sleeping area
CO Alarm
CO Alarms should not be located:
300 mm min from walls
In an enclosed space e.g a cupboard
Where it can be obstructed
Directly above a sink
Next to a door or window
Next to an extractor fan or vent
Where dirt & dust may block the sensor
In a damp or humid location
In the immediate vicinity of a cooking appliance
When only one CO Alarm is to be fitted, audibility of the
sounder may be a problem in other areas of the property - see
page 9 for information on how this can be overcome.
• 1-3m horizontally from the appliance
• At least 300mm from any wall and
obstructions (e.g. light fitting)
Wall Mounting Option
• 1-3m horizontally from appliance
• 150mm vertically down from ceiling
• Above the height of any doors
or windows
Innovative Design & Practical Features
Complete Visual Information
Three separate indicating LED's
provide visual information: healthy
mains supply, CO level
sensed/alarm status, and if a fault
is detected during the unit's
integral self-test.
The alarm LED varies its rate of flash depending upon the
CO level sensed - giving further information on any
dangerous levels of CO.
Operating the test button
will also activate the
memory feature and the
LED will indicate the previous
maximum CO level sensed.

BS EN 50291:2001
All Ei CO alarms carry the British Standards
Institute Kitemark to indicate that they
have been 3rd party tested, by BSI, to
BS EN 50291:2001. This replaces the previous
BS 7860:1996 and is a more demanding
The main change to the standard is a
lowering to the CO triggering levels
combined with new time/response limits to
protect more vulnerable people groups and
alleviate false alarms.
Rechargeable Lithium
Cells used in Ei261ENRC &
Ei261DENRC Models
High performance
rechargeable vanadium
pentoxide lithium cells are used
in the Ei261ENRC & Ei261DENRC
alarms and offer the most
effective and reliable back-up
power, giving a true 10Yr+ life.
Easi-fit Mounting Plate
(Ei261ENRC & Ei261DENRC)
As the cells are rechargeable,
they obviate the need for
battery replacement - saving both time and money. Also,
due to them being an integral part of the internal
circuitry, any possible casual removal is prevented.
Fix the mounting
plate supplied with
the alarm to the
ceiling or wall
during first fix. No
separate enclosure
is required.
The Easi-fit mounting plate included with Ei260 series
alarms has a built-in connector block with large, clearly
marked 'Easi-see, Easi-connect' wiring connections to
make wiring as simple as possible. Due to the unique
design, no extra pattress or mounting box is required,
saving valuable time and money.

Quick Test Feature
Operating the Test button activates the quick CO gas
test feature. The unit will then sample for CO 4 seconds
later and give an audible and visual warning if CO is
sensed - saving time and money particularly when
testing units in a large number of properties.
Reliable, Proven Sounder
Giving an output of 85dB(A) at 3m, the alarm signal is
loud. The piezo disc sounder element is securely held
with silicone mastic to prevent creepage and
premature failure. Soldered contacts on the disc further
improve reliability when compared to more commonly
used pressure contacts, which can be prone to failure
due to corrosion and arcing.
Replaceable CO Sensor
(Ei261ENRC & Ei261DENRC)
33% cost saving over
the life cycle of
comparable products
All CO sensors have a limited life of 5/6
years. But, the unique replaceable
sensor module on the Ei261ENRC &
Ei261DENRC alarms doubles the life
cycle of the product. This simple to
carry out process gives a significant cost
saving and eliminates any inconvenience in
time spent changing the entire unit.
Proven Electrochemical Cell Sensor coupled with
sophisticated electronics provides high quality
detection and reliability. Calibrated in CO gas during
manufacture, accuracy is assured.

The Problem
Audibility throughout the home is a priority, as a situation could
arise where a CO alarm is installed in a downstairs kitchen, which
has a fossil fuel burning appliance within it, and the alarm signal
may not be heard in the upstairs bedrooms or indeed other rooms.
The Solution!
Use the interconnect feature on the Ei261ENRC/Ei261DENRC to
connect to your existing Ei160RC smoke/heat alarm installation.
Then, you must introduce an Ei1529RC Alarm Control Switch
to provide control over the
whole system.
The interconnect feature allows the CO alarm to trigger all
Ei160RC mains smoke/heat alarms installed and vice-versa - giving
increased audibility in either a CO or fire situation. If all alarms are
sounding, pressing ‘Locate’ on the Ei1529RC Alarm Control Switch
will silence all the alarms except the alarm sensing a CO or fire
situation. This gives control over the system and allows occupants
to select the safest action and/or escape route.
Additionally, if found to be a false alarm, simply press ‘Hush’ on the
Control Switch to silence the alarm. The entire alarm system can
also be tested regularly by pressing the ‘Test’ switch.
