OVERVIEW
Introduction
The Intruder Alarm Control System TS2000 is provided for
large domestic and general commercial intruder
systems conforming to BS 4737 part 1 1986. It is an
extremely versatile system with the following facilities:
1. Will monitor up to 128 zones using various types of
detector device;
2. Will provide up to 136 output signals whose
response may be programmed;
3. May be programmed to provide a large number
of operational options and facilities.
As the system is microprocessor controlled it must be
programmed initially to select the required user options
such as number of zones, type of alarm and time of
operation. The general principle of operation is to
monitor protected zones, each having a detection
circuit, to detect the circuit status, then to respond
accordingly. As each zone has a circuit the terms Zone
and Circuit may be considered as being synonymous
but the term Circuit is generally used. Circuits may also
be grouped into wards.
Equipment
The system consists of a number of units that are
interconnected by a Control Network:
1. ControlPanel (CP):This isthe controllingpanelfor the
system which:
(a) provides power to the system;
(b) communicates with and monitors the state of
theunitsconnectedtothe ControlNetworkand
responds to alarm conditions according to the
pre-programmed instructions;
(c) provides special outputs to a printer, a Digital
Communicator, a Modem and other devices if
required.
It has no front panel controls and may be sited at any
convenient internal location.
2. NodeUnit (NU): aunit thatis remote fromthe CPand
is connected to it via the Control Network. It will
monitor the status of up to four circuits and will also
provideup tofour programmableoutputswhich are
controlled by the CP;
3. Remote Keypad Node Unit (REM): has the same
functions as the NU and in addition has a Keyboard
and a 40 character display to allow operators to
control the system.
The system will consist of a CP connected, via the
Control Network, to up to 32 NU’s and or REM’s so
providing up to128 circuits and programmableoutputs
each of whose functioning and use are
pre-programmed.Atleast oneREMisrequiredto control
the system.
CP Options
Additional boards may be fitted to the CP as follows:
1. SerialInterfaceBoard(SlB): Providesaserialoutput:
(a) RS232 format for a serial printer;
(b) RS232 format to any suitable equipment;
2. Parallel Interface Board (PIB): Provides up to eight
outputportswhichmaybe programmedto respond
to system activity and which can also be used to
provide outputs to a separate Digital
Communicator. It also has a (telephone) Line Fault
input port.
3. Digital Communicator type DC3 (Digicom): Will
transfer status information from the CP to a
dedicated Central Station via PSTN lines. When
activated via any of its eight logic input channels it
will:
(a) Dial one or two telephone numbers;
(b) Transfer an account (identity) number to the
dialled station;
(c) Transfer channel status information.
ModemtypeDC3M(Digimodem): Willtransfer dataover
PSTN lines to any suitable equipment such as a modem
for a computer terminal.When activatedthe system will
dial oneor two telephonenumbers and willbe capable
of transferring all commissioning information, event log
data etc., to a remote maintenance centre. The
remote maintenance centre may also call the DC3M
and transfer data to it.
