- monitoring of "Signal20P" PSK;

- display on the liquid crystal indicator of events occurring in the system;

- alarm alarm on built-in audible alarm;

- control of taking/removal and control of fire and security alarm loops.

"Signal20P" PSK device provides the possibility of connection of 20 fire alarm loops.

The display unit is designed to display the status of 60 loops or partitions in the Orion integrated system.

The C2000M remote controller, the block of indication S2000BI and devices of PPK "Signal20P" controlling 1 section are installed on a wall in dispatching office (room of a fire post).

"Signal20P" PSK devices, monitoring sections 2-8 are installed on the 1st floor near the SS riser in the locked panel.

Blocks of executive S2000SP1 relays are installed in cases of "ASCAPC" of devices floor distributive the UERM type.

All devices of the MS system (network devices) are connected to each other by KVP cable 2x2x0.52 (RS485 bus).

To prevent electrostatic interference and distortion of the signal due to reflection, the line (RS485 bus) must be loaded with 620 Ohm matching resistors on both sides.

PS system equipment power supply (the C2000M remote controller, the S2000BI block, the S2000IT block, devices of PPK "Signal20P" and blocks of executive S2000SP1 relays it is provided by the DC voltage of 24B from RIP24ZA17 stand-by power supplies with the built-in batteries 17 of Ach and it is carried out by cable VVGNG of LS 2x2.5.
