Once the failure is fixed, the control unit needs to be reset to its
normal operating status. Press the “Reset/Test button on the
front of the control unit to reset it.
Caution.
It is advisable to repeat the operating test at least
once a year, or after a prolonged period of stoppage and in any
case, every time the detector is replaced.
Caution.
The average lifetime of the UR13 and UR20S detec-
tors is 5 years from installation date. They must be replaced
before the end of the 5th year of use. The average lifetime of
detectors is calculated for use in a typical environment, nor-
mally free from polluting agents (gases, solvents etc.).
More frequent and higher concentrations of these substances
can accelerate the normal oxidisation process of the sensing
element, subsequently shotening its lifetime.
Gas Alarm
If an alarm signals a gas leak or the presence of carbon
monoxide, proceed as follows:
- put out flames and switch off all gas equipment;
- do not for any reason switch on or off lights or any electrical
equipment;
- open doors and windows to air the environment;
- look for and eliminate the cause of the alarm. If this is not
possible, leave the building and contact emergency services
from outside.
