Description
4098-9754 Simplex Analog Photo Sensor With Heat.
The 4098-9754 Simplex, TrueAlarm multi-sensor model 4098-9754 combines the established performances of a TrueAlarm photoelectric smoke sensor with a fast-acting and accurate TrueAlarm thermal sensor to provide both features in a single sensor/base assembly.
Digital Communication of Analog Sensing.
Analog information from each sensor is digitally communicated to the control panel where it is analyzed. The photoelectric sensor input is stored and tracked as an average value with an alarm or abnormal condition being determined by comparing the sensor’s present value against its average value. Thermal data is processed to look for absolute or rate-of-rise temperature as desired.
4098-9754 Simplex Intelligent Data Evaluation.
Monitoring each photoelectric sensor’s average value provides a software filtering process that compensates for environmental factors (dust, dirt, etc.) and component aging, providing an accurate reference for evaluating new activity.
The result is a significant reduction in the probability of false or nuisance alarms caused by shifts in sensitivity, either up or down. Status indications of dirty and excessively dirty are automatically generated allowing maintenance to be performed per device.
4098-9754 Simplex Control Panel Selection.
Peak activity per sensor is stored to assist in evaluating specific locations. The alarm set point for each TrueAlarm sensor is determined at the control panel, selectable as more or less sensitive as the individual application requires.
TrueAlarm photoelectric smoke sensing and heat-sensing combined in one housing to provide:
- Smoke activity accurately monitored by TrueAlarm photoelectric sensing technology.
- Thermal activity accurately monitored by TrueAlarm thermistor sensing technology.
- And TrueSense detection, a correlation of smoke activity and thermal activity providing intelligent fire detection earlier than with either activity alone.
For use with Simplex® 4007ES, 4010ES, 4100ES, and 4100U fire alarm control panels:
- TrueAlarm analog sensor information is digitally communicated to the control panel via IDNet two-wire communications.
- Special point types allow the 4098-9754 Simplex multi-sensor to communicate smoke and heat analog sensing data using only one IDNet address.
- Individual sensor information is processed by the host control panel to determine sensor status and to determine whether conditions are normal, off-normal, or alarm (4100U fire alarm control panels require software revision 11 or higher with multi-point compatible IDNet transmission modules).
