When setting up the SPA(S) notification signal transmission system, it is necessary to find out the ratio of the signal pulse duration to the interval of its overlap by the signal of the siren group. So, for 20 included group signals, the duration of the impulse signal in the SPA should be equal to 22. The value of this coefficient depends on the impulse power of the output signal and the signal overlap coefficient (knopping factor, C) of the input signal. In this article, the latest values of these coefficients are taken into account.
The notification signal transmission system on the FP-204/520/730 group of notification devices has been configured for the case when the output voltage in the group of notification devices is 24 V.
A brief overview of the features of digital outputs and the inclusion of single outputs with an internal MOS transistor in analog transmission and notification systems (NCT) on DC-class components.
A survey of representatives of companies specializing in the design and manufacture of public address systems showed that customers do not have much confidence in analog interfaces and that they are unlikely to want to use legacy analog outputs. Differential inputs and outputs, and in particular the possibility of connecting digital outputs and the corresponding digital inputs and outputs of interlocking, are less capable and do not guarantee system expandability f02ee7bd2b
