Autocall TrueAlarm Multi-Sensor Model A4098-9754 Providing TrueSense Early Fire Detection

UL ULC CSFM Listed Multi Point Analog Sensing Multi Sensor Model A4098 9754 Providing TrueSense Early Fire Detection Communication of Analog Sensing Analog information each sensor is digitally communicated to the control panel where is analyzed Photoelectric sensor input is stored and tracked as an value with an alarm or abnormal condition being determined by the sensor present value against its average value Thermal is processed to look for absolute or rate of rise temperature as Data Evaluation Monitoring each photoelectric sensor value provides a software filtering process that compensates environmental factors dust dirt etc and component aging an accurate reference for evaluating new activity The result a significant reduction in the probability of false or nuisance alarms by shifts in sensitivity either up or down Status indications dirty and excessively dirty are automatically generated allowing to be performed per device Panel Selection Peak activity per sensor is stored to assist evaluating specific locations The alarm set point for each TrueAlarm is determined at the control panel selectable as more or less as the individual application requires Reporting and CO Base Reference Reporting sub points under its single address varies with the base the A4098 9754 with CO sensor bases is detailed in data sheet Selection Alarm set points can be programmed timed automatic sensitivity selection such as more sensitive at night sensitive during day Control panel programming can also provide operation per sensor For example a 0.2 level may cause a to prompt investigation while a 2.5 level may initiate an alarm Alarm and Trouble LED Indication Each sensor base LED to indicate communications with the panel If the control panel that a sensor is in alarm or that it is dirty or has some other of trouble the details are annunciated at the control panel and that base LED will be turned on steadily During a system alarm the panel will control the LEDs such that an LED indicating a trouble return to pulsing to help identify the alarmed sensors 1 Multi Sensor A4098 9754 in Standard Sensor Base photoelectric smoke sensing and heat sensing in one housing to provide Smoke activity accurately monitored by TrueAlarm photoelectric technology Thermal activity accurately monitored by TrueAlarm thermistor sensing And TrueSense detection a correlation of smoke activity and thermal providing intelligent fire detection earlier than with either alone use with Autocall 4007ES 4010ES 4100ES fire alarm control TrueAlarm analog sensor information is digitally communicated to the panel via IDNet two wire communications Special point types allow the A4098 9754 multi sensor to communicate and heat analog sensing data using only one IDNet address Individual sensor information is processed by the host control panel determine sensor status and to determine whether conditions are off normal or alarm can be determined by either Smoke detection with selectable sensitivity from 0.2 to 3.7 ft Heat detection selectable as fixed temperature or fixed with selectable TrueSense intelligent analysis of the combination of smoke and heat design features Functional and architecturally styled enclosures for ceiling or wall Smoke sensor louver design that directs air flow to chamber enhancing Built in magnetic test feature Compatible with standard bases including relay control sounder capture and isolator bases Designed for EMI compatibility listed to Standard 268 Multi Sensor Description multi sensor model A4098 9754 combine the established of a TrueAlarm photoelectric smoke sensor with a fast and accurate TrueAlarm thermal sensor to provide both features a single sensor base assembly This product has been approved by the California State Fire Marshal CSFM pursuant to Section 13144.1 of the California Health and Safety Code See CSFM Listings 7300 2269 0560 7272 2269 0537 7300 2269 0551 7300 2269 0531 and 7300 2269 0550 for allowable

A4098 9754 Providing TrueSense Early Fire Detection Photoelectric Activity and Thermal Activity TrueSense correlates both thermal activity and smoke activity at a single location using an extensively tested covariance relationship a result TrueSense detection improves response to conditions of faster acting hot flaming fires when compared to the of either photoelectric smoke activity or thermal activity alone Integrity Detection TrueSense operation provides early fire and maintains the established high level of immunity to false and nuisance alarms that is inherent with TrueAlarm sensor Reference locations should be determined after careful consideration of physical layout and contents of the area to be protected Refer to 72 the National Fire Alarm and Signaling Code On smooth ceilings sensor spacing of 30 ft 9.1 m may be used as a guide For detailed application information refer to A4098 Detectors and Bases Application Manual document number Base Features mounted address selection allows the address of the multi base to remain with its programmed location when the sensor is for service red LED indicates power on by pulsing or alarm or trouble steady on reflecting status of either sensor The exact status of specific sensing element is annunciated at the fire alarm control Alarm Control Panel Features Individual smoke sensitivity and temperature operation is selectable for sensor integrity Sensitivity monitoring that satisfies NFPA 72 sensitivity testing Peak value logging allows accurate analysis for sensitivity selection Automatic once per minute individual sensor calibration check verifies Multi stage alarm operation Selectable alarm verification Automatic environmental compensation and determination of dirty excessively dirty TrueSense analysis of smoke and heat activity Ability to display and print detailed sensor information in plain English Smoke sensitivity displayed in percent per foot and temperature selectable as Fahrenheit or Celsius Analog Sensor Features mechanical Housing is sealed against rear air flow entry Electronics are EMI RFI shielded sensing Photoelectric light scattering sensing technology 360 smoke entry for optimum response Chamber screen provides protection from dirt dust and insects sensing Rate compensated self resetting operation Fast response thermistor design Control panel can select per sensor for fixed temperature sensing temperature sensing or the combination of both Sensing Details photoelectric sensors use a stable pulsed infrared LED source and a silicon photodiode receiver to provide consistent accurate low power smoke sensing Seven levels of sensitivity are for each individual sensor ranging from 0.2 to 3.7 per foot smoke obscuration Sensitivities of 0.2 0.5 and 1 are for special in clean areas Standard sensitivities are 1.5 2.0 2.5 and 3.7 Application type and sensitivity are selected and then at the fire alarm control panel head design provides 360 smoke entry for optimum smoke Because of the photoelectric sensing technology the sensor is UL listed for air velocity of up to 4000 ft min care must be taken in determining sensor locations to avoid where local airflow may also impact any smoke flow Refer to the reference section on this page Sensing Details heat sensors monitor a fast reacting thermistor providing that is self restoring and rate compensated Due to its small mass the sensor accurately and quickly measures the local for analysis at the fire alarm control panel The control allows alarm selection to be per sensor as fixed temperature or temperature or the combination of both Detection Rate of rise temperature detection is at the control panel for either 15 F 8.3 C or 20 F 11.1 per minute Fixed temperature sensing is independent of rate of rise and selectable to operate at 135 F 5
