4 DESIGN AND OPERATING PRINCIPLES
The device view along with its overall and mounting dimensions are
demonstrated by Appendix A.
There is “Ready” LED, indicating the device operating modes on the
device cover. On the device base there is the radioelement printed-circuit
board along with external connection terminals and tamper.
The device block scheme diagram is shown in the Appendix B.
The basic device components are:
−
power supply inputs
−
27 V voltage converter
−
5 V voltage converter
−
circuit switch
−
light indicator
−
relays
−
loop power dump unit
−
RS-485 interface converter
−
nonvolatile memory
−
tamper
The voltage is delivered from the alarm loop metering circuits to the
circuit switch. Controlling the switch, the processor subsequently connects
in-built analogue digital converter input to the alarm loops. In such a proc-
ess the loop resistance and loop status are estimated.
The 27 V voltage converter shapes stabilized loop supply voltage, the
5 V voltage converter shaping stabilized one for digital subcircuit.
