System Sensor InnovairFlex Duct Smoke Detectors

InnovairFlex Duct Smoke Dectectors Asked Questions is maintenance What does a maintenance condition mean a maintenance condition the sensor LEDs will blink red every 5 seconds and the power board LED blink amber as depicted on the LED chart provided Maintenance LED indications are also indicated the RTS2 and RTS AOS remote test accessory The maintenance condition means that the sensor is outside its original factory preset sensitivity and shall be cleaned or replaced frequently does a duct smoke detector need to be cleaned maintained to NFPA the detector should be visually inspected semiannually and functionally tested at once a year Testing and inspection may be needed more frequently depending on the air quality of duct supply air dry nitrogen be used to clean a duct smoke detector dry nitrogen can be used when cleaning a duct smoke detector the red cap on the end of the sampling tube be removed for cleaning replaced the endcap can be removed for cleaning purposes but needs to be replaced for proper operation the duct smoke detector do you test differential pressure reference Differential Pressure Testing Using Analog and Digital Manometer Whitepaper on are the terminal designation differences between the DH100 DH400 InnovairFlex reference Terminal Designation chart included in the installation manual which can be at systemsensor com flex the LED indications on the Power Board and Sensor of InnovairFlex duct detectors reference the LED indication reference chart in the installation instruction manual available at systemsensor com flex does InnovairFlex provide more flexibility to customers of the key InnovairFlex features include Versatile mounting options in square or rectangular configuration with modular any tools operators All conventional InnovairFlex models including the NEMA 4 version are designed operate at a broader operating temperature range from 4 F to 158 F and humidity range from 0 to 95 non condensing New sampling tubes for InnoairFlex allow installation and removal of tubes without the use As many as 50 InnovairFlex duct smoke detectors can be interconnected so that when one unit smoke all interconnected detectors will switch their relays however only the detector smoke will go into alarm to pinpoint the fire smoke source A D4S sensor only component can be connected to a D4120 4 wire conventional model in order to one power board to monitor both the supply and return side sensors without having to place a detector in each location A D4P120 power board component can be remotely mounted and wired to up to two D42 sensor The above and other flexible features of InnovairFlex will allow for easy installation and maintenance is the recommended cleaning procedure and needed First notify the proper authorities that the smoke detector system is maintenance and that the system will temporarily be out service Disable the zone or system undergoing maintenance to unwanted alarms and possible disbatch of the fire department If the sensor heads are not removed during the construction phase and sensor chamber becomes dirty causing a maintenance condition will not always be visible on the exterior black screen on the sensor the sensor head must be cleaned with compressed air To clean sensor head chamber follow the below step by step instructions Remove the sensor to be cleaned from the system Remove the sensor cover by pulling outward on each of the four tabs that hold the cover in place Vacuum the screen carefully without removing it Remove the chamber cover screen assembly by pulling it straight out Use a vacuum cleaner or compressed air to remove dust and debris the sensing chamber Reinstall the chamber cover screen assembly by sliding the edge over sensing chamber Turn until it is firmly in place Replace the cover using the holes for the LEDs for alignment and then pushing it until it locks into place Reinstall the detector If excessive dust is found in the detector housing and or sampling they should also be cleaned with a vacuum cleaner or compressed air smoke bombs an acceptable test option for duct smoke bombs are required in some jurisdictions but differential pressure is the preferred method System Sensor provide any guideline for trouble please reference the LED table on page 8 of the D4120 D4S and or D4P120 installation manual The installation manual is packaged with device and can also be accessed at systemsensor com System Sensor offer Technical Support technical support is needed please dial 800 SENSOR2 option 2 smoke testing is there a way to help clear out smoke in for the detector to reset InnoviarFlex duct smoke detector manufactured after August 27 2012 a new smoke clearing feature allowing the auxiliary contacts to close reset enabling the fan which will blow the remaining smoke out of sensing chamber after smoke testing allowing the detector to go into full reset a user separate a collocated InnovairFlex model to use as a sensor or power board component only co located model was not designed nor tested to be used as a sensor power component only Thus System Sensor does not recommend nor separating the co located model to be used as a sensor or power component only Customers can purchase individual components needed duct smoke detectors be installed during the final phase any unitary packaged air conditioning units are run during the drywall phase of any building under construction to accelerate the of joint compound the subsequent sanding of those drywall joints resulting dust may compromise the sensor heads in duct smoke To avoid this condition it is recommended that the sensor be removed during the construction phase and replaced once is completed and the Certificate of Occupancy is issued sensor heads twist out for removal and twist in for insertion does the detector go into a trouble mode all possibilities A trouble condition is created either due to a cover tamper issue an dipswitch setting for the number of sensors connected a loss of communication from the sensor For trouble shooting a slight difference in the LED indications has been provided distinguish between the different possible causes Cover tamper and incorrect dipswitch setting are indicated by constant LED indication Loss of communication from the sensor is by a long amber LED blink 10 seconds on 1 second off refer to the attached LED table for details The cover tamper condition dipswitch settings or communication loss the sensor has to be addressed in order to bring the DSD to a state If the detector was manufactured prior to August 27 2012 a trouble at the panel may be associated with maintenance A condition is indicated by an amber LED blink on the and a red LED blink on the sensor every 5 seconds This a true maintenance condition and requires removing the head and or replacing it The sensor should be cleaned in the event that the sensor LED are red and the power board LED are blinking amber every 5 This is a true maintenance condition and requires removing head and cleaning or replacing it At the fire alarm control panel trouble conditions will be displayed the same manner For units manufactured after August 2012 conditions are displayed locally at the detector or remote accessory Trouble communications are not sent to the fire alarm panel System Sensor HVFL13501 9 12
