TrueAlarm Multi-Sensor Model 4098-9754
Features
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
TrueAlarm Multi-Sensor Description
TrueAlarm multi-sensor model 4098-9754 combine 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.

Timed/Multi-Stage Selection.
Alarm set points can be programmed for timed automatic sensitivity selection (such as more sensitive at night, less sensitive during day). Control panel programming can also provide multi-stage operation per sensor. For example, a 0.2% level may cause a warning to prompt investigation while a 2.5% level may initiate an alarm.
Sensor Alarm and Trouble LED Indication.
Each sensor base’s LED pulses to indicate communications with the panel. 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 control panel and that sensor base’s LED will be turned on steadily. During a system alarm, the control panel will control the LEDs such that an LED indicating a trouble will return to pulsing to help identify the alarmed sensors.
