Due to its small thermal mass, the sensor accurately and quickly measures the local temperature for analysis at the fire alarm control panel. Rate-of-rise temperature detection is selectable at the control panel for either 15° F ( 8.3° C) or 20° F ( 11.1° C) per minute. Fixed temperature sensing is independent of rate-of-rise sensing and programmable to operate at 135° F ( 57.2° C) or 155° F ( 68° C) . In a slow developing fire, the temperature may not increase rapidly enough to operate the rate-of-rise feature. However, an alarm will be initiated when the temperature reaches its rated fixed temperature setting. TrueAlarm heat sensors can be programmed as a utility device to monitor for temperature extremes in the range from 32° F to 155° F ( 0° C to 68° C) . This feature can provide freeze warnings or alert to HVAC system problems. Refer to specific panels for availability. General features: • UL listed to Standard 268 • Louvered smoke sensor design enhances smoke capture by directing flow to chamber; entrance areas are minimally visible when ceiling mounted • Designed for EMI compatibility • Magnetic test feature is provided • Optional accessories include remote LED alarm indicator and output relays Digital Communication of Analog Sensing. TrueAlarm analog sensors provide an analog measurement digitally communicated to the host control panel using Simplex addressable communications. At the control panel, the data is analyzed and an average value is determined and stored. An alarm or other abnormal condition is determined by comparing the sensor’ s present value against its average value and time. Intelligent Data Evaluation. Monitoring each sensor’ s average value provides a continuously shifting reference point. This software filtering process compensates for environmental factors ( dust, dirt, etc.) and component aging, providing an accurate reference for evaluating new activity. With this filtering, there is a significant reduction in the probability of false or nuisance alarms caused by shifts in sensitivity, either up or down. 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 host control panel, selectable as more or less sensitive as the individual application requires. Timed/ Multi-Stage Selection. Sensor 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 a sensor is in alarm, or 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.
