mounting adapter Designed for EMI compatibility Magnetic test feature CO sensor element is easily replaced when end of service life reached Access to CO sensor replacement cartridge CORC requires removal of interchangeable sensor head sensor base description monoxide CO is an odorless colorless tasteless gas by the incomplete combustion of heating fuels such as coal heating oil and natural gas CO is also a byproduct of materials experiencing unintentional fire or even incipient fire Monitoring of CO levels can warn of physically harmful however sensing of CO levels below the harmful can also provide improved understanding of incipient fire when evaluated in combination with photoelectric fire sensor from the same location CO sensor bases combine an electrolytic CO sensing module a TrueAlarm analog sensor to provide a single multiple sensing using one system address The CO sensor can be enabled used in LED Switch modes and custom control and can be public for communication across a fire alarm Network ULC CSFM Listed FM addressable CO sensor base with 520 Hz sounder CO toxic gas monitoring and enhanced fire detection CO sensor bases with 520 Hz tone require a TrueAlarm photoelectric or heat sensor ordered separately CO sensor bases with 520 Hz tone are multi point devices use a single address and receive communications and sensor power from IDNet channel the sounder base requires separate 24 VDC system or NAC connection IDNet circuit allows the sounder to be supervised and coded by NACs allowing synchronized temporal march time or channel coding For use with 4007ES and 4010ES or 4100ES fire alarm control units software revision 2.01.02 or higher For use with 4100U fire alarm control units with software revision or higher Listed to UL 268 UL 464 UL 2075 ULC S529 and CSA 6.19 01 Two types of CO influenced operation are available UL 2075 CO level monitoring for ventilation control and multi criteria fire analysis combining optical and CO gas monitoring information sensor base with photoelectric or photo heat sensor Independent sensor operation or selectable multi sensor modes for alarm reduction or faster detection CO and photoelectric sensors can be analyzed together to reject non conditions that can trigger false alarms steam dust etc An increased sensitivity algorithm analyzes CO and photoelectric information to allow the presence of CO to increase sensitivity for high value locations museums electrical rooms etc Hz Sounder base operation Low frequency sound output 520 Hz at 85 dBA The base can supervise the sounder drive circuit when an AUX 24V line is used for sounder power Alternatively base supervision be disabled if a supervised NAC is needed to power the sounder coded outputs When connected to a panel NAC through the 4905 9835 Temporal Module the sounder base can provide temporal code 3 TC3 for or temporal code 4 TC4 for toxic carbon monoxide alarms 4905 9835 module may also be used to code other non fire carbon monoxide notification appliances refer to data sheet Sounder can be manually activated from the unit 520 Hz Sounder Bases are listed for Special Application when used a compatible NAC circuit unit

the presence of the CO sensor mounted address selection allows the address to remain with its when the sensor is removed for service or type change Address is from the front under the removable sensor An integral red indicates power on by pulsing or alarm or trouble when steady on also provides test mode status Detailed status is available at the fire control unit sensing detailed operation Gas Sensing UL 2075 For CO toxic gas detection the bases toxic gas sensing to the UL 2075 standards Toxic gas sensing be selected at the same time as any of the combined CO photo fire modes are selected Gas Sensing OSHA Compliant For OSHA compliant gas sensing desired threshold level above 30 ppm is selected at the control unit required for the application typically for ventilation control Refer to 3 for additional OSHA CO monitoring information Fire Sensing Each sensor provides an analog measurement communicated to the control unit for analysis At the unit analog values are used separately or combined to evaluate for indicative of fire incipient fire excessive heat and freeze For fire the addition of a CO sensor provides two selectable of operation Nuisance Alarm Reduction Mode and Faster Detection These two modes were developed using the results extensive testing of actual fires performed under a wide variety of Refer to page 4 for additional operation mode options Alarm Reduction Mode allows the host control unit to photoelectric sensor input and CO sensor level input to reduce alarms caused by non fire conditions Non fire conditions can be from bathroom showers particles from dusty environments from personal care products tobacco smoke cooking smoke other similar conditions Alarm Reduction Details For applications of anticipated alarm conditions photoelectric sensitivity is normally selected 3.7 ft smoke obscuration However the addition of CO sensing the host control unit to apply software verification similar to the alarm verification feature often used with conventional smoke Fire Detection For applications where faster response to or slow building fires is desired and environment appropriate Faster Fire Detection mode correlates the outputs of the CO sensor the photoelectric sensor to provide increased sensitivity This provides earlier detection compared to a standard sensitive sensor setting and also provides more false alarm compared to using a sensitive setting in an area not normally appropriate Fire Detection Details TrueAlarm photoelectric sensors can selected to be as sensitive as 0.2 ft obscuration for applications as appropriate to that level However if the environment is suitable for that sensitivity level the Faster Fire Detection mode the photoelectric sensor to be selected as a standard 2.5 obscuration but with the presence of a significant level of CO the of CO and photo sensing input can allow an equivalent approaching 0.5 ft obscuration The host control unit two photoelectric sensitivities the one selected for photoelectric only typically 2.5 and the CO correlation sensitivity that it depending on the amount of CO present 4098 9773 CO Sensor Base with 520 Hz Sounder unit operations sensor features include
