SIGNAL-20P DESIGN AND OPERATING PRINCIPLES

The processor controls device operating as whole:

− subsequently requests alarm loops and monitors their statuses

measuring their resistances

− controls the internal light indicators, relay and loop power dump unit

− receives the commands from net controller and transmits mes-

sages to this one via RS-485 interface

In order to accord with the 2-lined RS-485 the interface converter is

used.

The nonvolatile memory is designed to story the event messages

along with the time and date of their origins.

4.1 Alarm loops

The device monitors twenty alarm loops and depending on their

statuses generates the alarm and service messages transmitting them to

the net controller (either ARM Orion or S2000/S2000M console), and con-

trols five in-built relays.

The alarm loop status is defined by its type, its resistance and by its

logical state that is armed or disarmed.

All DC voltage detectors both burglary and fire can be included into

alarm loops, with internal detector resistance in “Fire” mode being:

− no more than 2,7 kOhm for normally opened detectors

− no more than 3,2 kOhm for normally closed detectors

4.1.1 The loop configuration parameters

The alarm loop control algorithm can be changed by varying the loop

configuration parameters that can be viewed in Table 2.
