The National Radiological Protection Board (NRPB), UK have carried out extensive tests on Ei
professional Ionisation Smoke Alarms and have concluded that they are radiologically safe. They
estimate that we recieve 10,000 times as much radiation from our surroundings as we would from
an ionisation alarm in normal use.
A domestic Ionisation Smoke Alarm can be disposed of with normal household waste. (This is
provided that the other waste is not radioactive and that the total amount of Americium 241
radioactivity is less than 40 kilobecquerels per 0.1 cubic meters of waste). A smoke Alarm contains
33 kilobecquerels of Americium 241. Essentially, this means that only one Ionisation Smoke Alarm
can be put in a normal size dustbin. Alarms containing a NiCad battery must not be disposed of in
domestic waste. See 27 below.
The early 150 series alarms contained a NiCad battery and some may now be reaching their end
of life. The Cadmium contained within the battery is a restricted substance under The Batteries
and Accumulators Regulations 1994 and cannot be disposed of in normal waste. Aico Ltd and
Ei Electronics take their responsibilities to the environment seriously, and will accept redundant
Ei product back for recycling/disposal. The Ei151TL, Ei156TL, Ei156TLH, 140 and 160 series do
not contain NiCad batteries, so are not subject to disposal restrictions (other than those in section
26 above).
These have been designed to be fully compatible with previous Smoke and Heat Alarm models.
Therefore if an old model 150 series mains powered alarm should require replacement, the
equivalent model in the new 150 series can be easily and safely installed in it’s place. All current
140, 150 and 160 series alarms are also fully compatible with each other.
Ei Professional Alarms are designed and manufactured by Europe's largest producer of Smoke and
Heat Alarms, with over 30 years experience in producing quality life safety devices. The latest
techniques are used in the manufacturing process, with the highest quality and reliability standards
(including BS EN ISO 9001: 2000) being practised to ensure trouble-free performance. Smoke and
Heat Alarms are fully 3rd Party tested and Kitemarked to the relevant British Standard (BS 5446:
Pt.1: 2000 for Smoke Alarms, BS 5446: Pt.2: 2003 for Heat Alarms). All the alarms are easily
installed and come with comprehensive instruction leaflets and a 5 year guarantee.
PLEASE NOTE: The information contained in this leaflet is only a summary of some of the key
points about our Smoke and Heat Alarms. It is not intended to replace the instruction leaflet
supplied with the product.
Smoke and Heat Alarms must be installed by a qualified person according to the recommendations
contained in whichever of the following documents are relevant to the specific installation;
BS 5839: Pt.6, Building Regulations and I.E.E. Wiring Regulations. The information supplied in this
leaflet is believed to be in conformity with these codes. However, Ei Electronics and Aico Ltd cannot
be held responsible for ensuring the Smoke and Heat Alarms, as installed, are in compliance with
these codes. This is the responsibility of the installer and we recommend that the original source
documents are consulted to achieve this end.
