Signal-10 Operation Principles

COMMUNICATIONS BETWEEN THE SIGHNAL-10 AND A NETWORK CONTROLLER

The Signal-10 device can operate both standalone (automatically activating relay outputs in accordance

with the programmed logic depending on related loop(s) status) and as part of an Orion security system

under controlling of a network controller which can be either S2000/S2000М Fire and Alarm Console or

a PC with ARM Orion/Orion Pro software installed.

Operating as a part of an Orion system, the Signal-10 maximizes its operability. The Signal-10 trans-

mits to the system all monitored data such as smoke addressable detector conditions, if any, alarm loop

statuses, arming/disarming attempts, troubles of the loops, relay outputs, the device itself, and so on.

All this information can be output to be observed by an operator or a security administrator, or written

into a log for following analysis or reporting, or be output to external indicator modules, or be used with-

in complicated automatic system control scenarios. The Signal-10 operating in on-line mode, its relay

outputs can be controlled centrally and remotely (see Centralized Output Control section of this Manu-

al), its alarm loop can be centrally remotely armed/disarmed (see Centralized Remote Arm-

ing/Disarming section of this Manual), as well as current resistance values of alarm loop with all the

devices included can be measured remotely (in kΩ or ADC units).

In order to identify the Signal-10 uniquely within an Orion system, a unique network address ranged

from 1 to 127 must be assigned to it while programming. This address must coincide with no other de-

vice address in the Orion system. The Signal-10 will transmit all the data to the network controller from

this address and receive all control commands from the network controller while communicating data

over RS-485 interface. The network address can be assigned to the Signal-10 either by network con-

troller tools or by means of UProg.exe configuration tool ⎯ see Signal-10 System Settings section of

this Manual.

For systems with a complicated topology, for example, where RS-485 interface is to be converted into

other interfaces intended to be transmitted via local networks, fiber optic, or radio channels, there can

be some transmission delays occurring. In such a case a value of the special system parameter Re-

sponse Pause can be increased to provide proper transmissions (see Signal-10 System Settings sec-

tion of this manual).

Transmitting Messages to a Network Controller

Being connected to an Orion network controller (either S2000/S2000М Fire and Alarm Console or ARM

Orion/Orion Pro Workstation), the Signal-10 automatically transmits the network controller messages

about its condition and a number of events including changes of loop statuses, relay output conditions,

addressable detectors being brought to threshold addressable loops and so on.

All the messages are transmitted over the RS-485 system interface. The data transmission parameters

are:

− 9600 Bd

− Half-duplex
