Response time

The response time of the sensor is, relatively speaking, the “speed of reaction” to the monitored event. Indicated by the time that elapses between the event being recorded and sending a signal to the control panel and/or turning on its own siren.

Theoretically, the shorter the response time of the sensor, the higher the overall reliability of the system, the faster it is able to respond to an event. At the same time, it is worth noting that in most models this time is measured in hundredths of a second — on average, from 0.03 to 0.15 s. Such a difference is fundamental only in very specific situations, when the count really goes to fractions of a second — for example, if a sensor is used to stop an industrial mechanism when a person appears in a dangerous area. In simpler cases, this parameter can be ignored.

Working hours

Operating time of the self-powered sensor on one set of batteries or battery charge (see "Power"). Note that this indicator is quite approximate — it is usually indicated either for an perfect or for a certain “average” mode of operation. The real battery life also depends on a number of practical nuances: the frequency of operations, the communication range, the level of interference, etc., up to the air temperature. So in fact, the operating time may differ from the claimed one, and in the other direction. Nevertheless, according to this characteristic, it is quite possible to both evaluate the overall battery life of the sensor and compare different models with each other: the difference in the indicated operating time usually fully corresponds to the difference in real battery life.

Note that modern sensors have very low power consumption, so their operating time is calculated in months.

Operating temperature

Ambient temperature range in which the sensor is guaranteed to remain operational.

All modern sensors are able to transfer the temperatures typical for residential and office premises without consequences. Therefore, it makes sense to pay attention to this parameter mainly in those cases when the sensor is planned to be used in more unfavorable conditions — for example, on the street, in an unheated room, in a “hot” industrial workshop, etc. At the same time, we emphasize that even for the most "Heat-resistant" models are undesirable exposure to direct sunlight — they can heat the case to temperatures that are much higher than permissible.
