CONVENTIONAL DETECTORS<br />
1043/221 Smoke detector with base<br />
1043/222 Smoke detector with base and relay output<br />
Smoke detectors work by detecting the scattering of light in caused by particles<br />
of smoke in the air. Device with automatic gain control function: a microprocessor<br />
calculates reading compensation to ensure constant sensitivity in time and correct<br />
the increase of level caused by the deposit of dust inside the analysis cell.<br />
Smoke detectors must not be installed in places where there are no currents<br />
of air which could deviate the flow of particles produced by combustion. They<br />
must not be installed in places where gassy materials are released by everyday<br />
activities. EN54 part 54 compliant - Certification number: 1438 - CPD - 0061.<br />
1043/223 Smoke detector with base<br />
1043/224 Heat detector with base and relay output<br />
Heat detectors monitor the temperature inside the area where they are installed.<br />
A microprocessor analyses and compares the signal received from an NTC type<br />
precision temperature sensor and trips an alarm if the temperature exceeds 58°C.<br />
EN54 part 5 compliant.<br />
1043/225 Velocimetric heat detector with base<br />
1043/226 Velocimetric heat detector with base and relay output<br />
Velocimetric heat detectors monitor the temperature inside the area where<br />
they are installed. A microprocessor analyses and compares the signal received<br />
from a precision microprocessor of the NTC type which activates the alarm<br />
if the temperature increase exceeds 5°C a minute.<br />

1043/231 Optical heat detector with base<br />
1043/232 Optical heat detector with base and relay output<br />
Dual technology (smoke-heat) detectors work by detecting the scattering<br />
of light in caused by particles of smoke in the air (Tyndall effect) and by monitoring<br />
the temperature in the area where they are installed. A microprocessor analyses<br />
and compares the signal received from a precision microprocessor of the NTC<br />
type which activates the alarm if the temperature increase exceeds 58°C<br />
a minute. Equipped with automatic gain control function: a microprocessor<br />
calculates reading compensation to ensure constant sensitivity in time.<br />
