2006年11月1日 · Here RTI is the response time index of a detector that indicates a thermal response sensitivity of the sensing element to the surrounding hot gas (mostly air) originated …

The 5151 thermal detector meets the needs for applications where rapid response is vital and rapid temperature increases would only be caused by a fire emergency. The detector initiates …

2006年11月1日 · As heat detectors are not only being used as a warning device but also widely used as a trip device of automatic fire suppression systems, it is increasingly desirable for a …

Areas with relatively stable temperatures (no rapid changes) can use the FST751R with the rate-of-rise feature for a quicker response. In general, each FST detector uses one of 159* …

In general, this System Sensor 5451 detector contains a unique dual thermistor heat sensing circuit that provides maximum performance and solid-state reliability. It initiates an alarm in …

The System Sensor 5151 thermal detector meets the needs for applications where rapid response is vital and rapid temperature increases would only be caused by a fire emergency. The …

RATE-OF-RISE: A temperature increase at the sensor of 15°F (9°C) or more per minute activates the rate-of-rise feature. This closes the contacts in the sensor to transmit the alarm condition …

2008年4月14日 · Once you know the specs, you can use a very small (very low thermal time constant) thermistor or temp meter, and heat source, and confirm that your testing method is …
