Overview:
Natural gas is one of the safest forms of energy in use
today, Its fitted as standard to all homes in the UK
however it is possible to cause problems through:
• Mistakes such as forgetting to light a gas ring
• Natural causes like a pilot light blowing out
• Faults in old equipment
This becomes
a bigger problem where there are confused, elderly or
infirm people who may be less aware of what is going on
around them. In the worst case, leaking gas can build up
to dangerous levels which can result in explosions.
The Amos
550 Natural Gas Detector (with optional valve) provides
two key functions
• It detects leaks long before the gas reaches unsafe
levels,
• It actively prevents danger by shutting off the gas
supply to the appliance
Where can the detector be used?
The detector is specially designed for all
household situations. In particular where appliances may
be left unattended or there
is a risk of gas flames blowing out or being forgotten
to be lit. It is mainly used for gas cookers but also
can be used to protect fires
and other gas appliances.
How it works:
A simple gas detector (similar in size and operation to
a smoke detector) is sited above the gas appliance. When
gas leaks happen they are detected well before levels
reach recommended safety limits.
When a leak is detected a red warning light comes on and
an optional alarm sounds. Remote alarms can also be
triggered.
An optional cut off valve can be connected into the gas
supply feeding the appliance. With this valve, when a
leak is detected, the gas supply to the appliance is
automatically switched off, making the situation safe.
When the gas has dispersed the gas can be reconnected
either automatically, when a button is pushed or only
when a key is inserted. This last option allows only
selected people to reconnect the gas.

Amos gas detectors have been used for many years in a
wide range of applications where gas presents a risk to
life or property. Our extensive experience in detector
design and manufacture has made us the detector of
choice for many councils, companies and housing
associations.
