UNDERSTANDING THE

Digital Display

Bar Graph to show early build up of CO
To understand the role of the product
indicators please refer to section ‘Carbon
Monoxide and how it can affect your family’
on page 3. The alarm has a bar graph which
mimics the way CO levels build up in the
blood stream. The response times of the
alarm are determined by the European
Standard EN 50291-1: 2010 so the alarm
will only sound when it has detected CO
for a prescribed length of time, the higher
the level of CO the quicker the alarm must
sound. However with FireAngel’s CO-9D
there is an early visual warning that CO is
present. When CO is first detected the alarm
indicates it’s presence by displaying the level
on the screen in parts per million (ppm). If
CO continues to be present additional bars
will appear on the graph. When the graph
is full i.e. the 6th segment is shown the unit
the alarm is working correctly. If you have any
questions about testing the sensor please
contact the technical support team (see page
21 for freephone and email contact details).
