Where should Gas & Carbon Monoxide Detectors be fitted?
Combined Gas & Carbon Monoxide (CO) detectors should be fitted in all rooms with a fuel burning appliance such as a boiler or
gas cooker and where a lot of time is spent e.g. the kitchen or living room.
They should not be fitted in the bathroom or areas subject to steam, damp or humidity.
Choosing a Location
The combined gas & CO detector should be wall mounted in the highest part of the room, approx 300mm from the ceiling and
between 1 and 5 metres from the appliance.
The combined gas & CO detector should not be located inside a cupboard, behind a curtain, directly above the cooker or sink, next
to a door or window or near an extractor fan.
The combined gas & CO detector should be within 5 metres of a mains supply otherwise the cable provided will need extending.
Typical Tools Required
Be careful when using step ladders –always face the direction you are working.
Always make sure the correct drill bits and screwdrivers are used.
Installation
1. IMPORTANT: BS EN50244:2016 Electrical apparatus for
the detection of combustible gases in domestic premises
states that detectors should be permanently installed
and it should not be possible to switch off power to the
device, unless for maintenance. A plug and socket type
connection should not be used, due to the ease with which
the detector may be disconnected from the power supply.
2. Fix the mounting plate complete with detector to the
wall using the screws and plugs provided through the
4 fixing holes “A”.
3. The detector should be wired to the mains supply by a
qualified Electrician using the flexible cable provided to a
fused spur outlet fitted with a 3A fuse to BS1363-4 and
BS1362 respectively, or according to local regulations.
4. Apply the mains power and the GREEN ON light will FLASH
for about 2 minutes during the sensor warm-up period.
The unit is operating when the GREEN ON light is lit steady.

Testing & Registering the Gas & CO Detector
The TRANSMIT GAS and TRANSMIT CO pushbuttons on the lid
are used when registering the combined Gas & CO detector
onto the warden call system, at-home alarm or Nursecall system.
See the following pages for how to put each of these products into registration mode.
The range of all radio devices can be affected by the working environment,
always take care during installation and perform several test calls.
Important Note on Sensor Testing
The gas and CO detector should be functionally tested every 6-12 months (depending on location).
The gas sensor can only be tested with calibrated test gas, never test using neat gas as this will poison the sensor.
The CO sensor can only be tested with calibrated test CO, this will take less than 1 minute to trigger.
For test gas supplies please contact Duomo.
In Case of Gas Alarm
If gas is detected the RED “ALARM GAS”light will illuminate, and the audible alarm will sound.
Put out all naked flames.
Don’t smoke. Don’t use naked flames.
Don’t turn electrical switches on or off.
Turn the gas off at the supply.
Open windows and doors to ventilate the area.
The alarm will silence when the gas is cleared. If the alarm continues to sound and the leak cannot be found, vacate the premises
and inform the Gas Emergency Service immediately.
In Case of Carbon Monoxide Alarm
If carbon monoxide is detected the RED “ALARM CO”light will illuminate, and the audible alarm will sound.
Open windows and doors to ventilate the area.
If the alarm stops it is safe for a qualified person to find the cause of the alarm.
If the alarm continues turn the appliance off and do not use until it has been checked by a qualified person.
Get medical help for anyone suffering headaches or nausea, advise that carbon monoxide poisoning is suspected.
In Case of Fault
If the YELLOW “FAULT”light illuminates the self test feature has detected a fault with the sensor.
The unit is probably defective and must be replaced.
After 6 years the YELLOW light will blink continuously, and the unit will emit a beep every hour.
The sensor has exceeded its useful life and must be replaced.
False Alarms
It is possible aerosol sprays, alcohol used in cooking, cigarette, cigar or
pipe smoke, gas from a cigarette lighter, strong household cleaning
agents, polishes or solvents may cause false alarms.
Cleaning and Care
It is recommended to clean the gas & CO detector periodically using the nozzle attachment on a vacuum
cleaner to remove dust, insects and cobwebs from the cover slots.
The detector can be wiped clean with a damp cloth, never use detergents or polish etc.
Avoid spraying any aerosols near the detector.
Decorating
Never paint the gas & CO detector itself.
Unplug the mains supply and cover the detector when decorating to
avoid contamination from water or dust.
Battery Life
The transmitter battery is checked once a day, if the voltage falls and stays below a preset level for 7 consecutive days a low
battery alert is automatically transmitted. Once a low battery call is received the gas & CO detector should be replaced within 7
days. The gas & CO detector must be returned to Tynetec/Aidcall for battery replacement.
Detailed information on battery management for all Tynetec/Aidcall products is available - request Doc No. FM0630.
