ACCESSORIESIntelligent sensors <strong>for</strong> controlling the <strong>fans</strong>Sensors which make it possible to sense certain environmental conditions <strong>and</strong> automatically startup the <strong>fans</strong>. This makes it possible to use the ventilation only when necessary. Using the sensorswith the frequency inverters we can control the regime of operation of the <strong>fans</strong>, thus preventingthe fan always working at its maximum consumption. These systems involve a significant energysaving.SI-PIR-TF-CenitalSI-PIR-TF-MuralSI-PIRMotion detectorAutomatically activates the ventilation system when it detects the presence of peoplewithin its radius of action <strong>and</strong> keeps functioning <strong>for</strong> a pre-set time, which can beadjusted by means of an internal clockModelPowersupplyOutputDetectionangleAdjustmentsHeightinstallationWorkingtemperatureSI-PIR 230V 230V 360ºC Timing 5s-30 min 2.4-4.2 m -20ºC +50ºCSI-PIR-TFT-550-B 24V ac/24V dc 24V ac/24V dc 110ºC Timing 5s-30 min 1.8-3.6 m -20ºC +50ºCSI-PIR-TF-25-360 24V ac/24V dc 24V ac/24V dc 360ºC Timing 10s-30 min 2.4-4.2 m -20ºC +50ºCSI-SMOKETobacco smoke detectorAutomatically activates the ventilation system when tobacco smoke <strong>and</strong> <strong>other</strong> contaminantsexceed the pre-set value in the sensor <strong>and</strong> keeps functioning <strong>for</strong> a pre-set time, which can beadjusted by means of an internal clockModelPowersupplyOutputMaximumcurrent (A)AdjustmentsHeightinstallationWorkingtemperatureSI-SMOKE 220-240V ac 220-240V ac 3.0 Timing 3min-20 min 1.5-2.0 m -20ºC +50ºCSI-CO2Air quality detectorAutomatically activates the ventilation system when the increase in contamination, as a functionof the occupation of the premises, exceeds the pre-set valueModelPowersupplyOutputConsumption(W)AdjustmentsHeightinstallationWorkingtemperatureSI-CO2-GAQ24 24V ac 0-10V ac 5 Timing 10s-30 min 1.5-2.5 m -20ºC +50ºCModelSI-TEMPTemperature sensorAutomatically activates the ventilation system when it detects a temperature greater than thepre-set value.
