Housings with TrueAlarm Photoelectric Sensor Available with Multiple Relay Control Sensor Operation Communication of Analog Sensing Analog information from the sensor is digitally communicated to the control panel where it is analyzed input is stored and tracked as an average value with an alarm or abnormal condition being determined by comparing the sensor present against its average Data Evaluation Monitoring each photoelectric sensor average value provides a software filtering process that compensates for factors dust dirt etc and component aging providing an accurate reference for evaluating new activity The result is a significant in the probability of false or nuisance alarms caused by shifts in sensitivity either up or down Panel Selection Peak activity per sensor is stored to assist in evaluating specific locations The alarm set point for each sensor is determined the control panel selectable as the individual application requires Status LED Each sensor housing red status LED located on the electrical interface board pulses to indicate communications with the If the control panel determines that a sensor is in alarm or that it is dirty or has some other type of trouble the details are annunciated at the panel and that sensor housing status LED will be turned on steadily During a system alarm the control panel will control the LEDs such that LED indicating a trouble will return to pulsing to help identify any alarmed sensors Remote Status Alarm LEDs track the operation of the sensor LED Please note that smoke detection in air ducts is intended to provide notification of the presence of smoke in the duct It is not intended to and will replace smoke detection requirements for open areas or other non duct applications Sensing photoelectric sensors use a stable pulsed infrared LED light source and a silicon photodiode receiver to provide consistent and accurate power smoke sensing duct sensor applications require less sensitive settings such as 2.5 per foot obscuration due to the ducts being a relative dirty However the standard seven levels of TrueAlarm sensor sensitivity are available for each individual sensor ranging from 0.2 to 3.7 foot of smoke obscuration Sensitivity is selected and monitored at the fire alarm control panel Alarm Control Panel Features Individual smoke sensitivity selection Sensitivity monitoring that satisfies NFPA 72 sensitivity testing requirements Peak value logging allows accurate analysis for sensitivity selection Automatic once per minute individual sensor calibration check verifies sensor integrity
