Alarm
message DTMF signal off time (Burst OFF time): 50 ms
minimum 400 ms maximum
Note:
Contact ID protocol requires Burst ON and OFF times to be 50 ms minimum and 60 ms maximum.
Handshake tones:
1400:
1400+/- 1Hz, duration of 100 ms +/- 1.5 ms, silence period of 100 ms +/-
1.5 ms, and

Electrical
characteristics for each line:
High voltage isolation: 1500VRMS between lines and RS232C connector.
Ring
signal detector: opto-coupler
Signal
isolation: telephone coupling transformer
Off-hook impedance: 50 ohms typical
High
ON-hook impedance is obtained by off-hook mechanical relay.
Handshake
tone is produced after 1.8 seconds when the off-hook relay is turned on.
RS232C Interface:
Speed: 9600 and 151200 baud, with one stop bit, no parity bit
The
interface signals: Receive Data, Transmit Data, Data Set Ready, Clear-to-send,
and ground. CTS signal controls for output to PC.
Cable
(25-pin M/9-pin F) is provided.
Received
alarm messages are computed for the checksum.
Dimensions: 6x7x2 in inches
Weight: 2 lbs. (1 kg).
Environmental: Operating temperature: 0 to 35 degree
C, Humidity: 85% RH at 35 degree C
Warranty/Service: 6 months limited warranty. No warranty
if any factory seal is broken. Service is performed at the factory, usually
within 5 working days.

Digital Security controls format
This CT400 is configured to simulate sur-gard MLR2E, Multi-Line Digital Receiver with the following
special specifications:
Baud rate: 115200
Parity: none
Data bit: 8 total
Stop bit: 1
By using Hyperterminal software, the following parameters and modes
are programmable:
1. CT400 Control Register may be read by “QAE”
or written by “MAE(n1)(n2)” where (n1) and (n2) forms
hexadecimal noted byte. ASCII character “C” is responded by CT400 after the
write operation. The CT400 responds with 19, which is factory default condition
after the memory read “QAE”.
The bit patterns of
CT400 control register is:
Bit 0(least
significant): 0 for 9600 baud, or 1 for 115200(factory default)
Btt 1: 1: add “L(line
number)” for non-SUR-GARD mode
Bit 2: 1:No PC (automatic kissoff generation without PC acknowledgement) 0:
acknowledgement required by PC(default)
Btt 3: 1: SUR-GARD mode (default), 0: regular mode
Bit 4: 1: generation of
heart-beat
2. heart-beat rate
To read the current
heart-beat rate, QA8. CT400 outputs 0A, which sets five seconds as factory
default condition. Each count is 0.5 second. To enter a new heart beat rate for
2 seconds interval, enter MA804.

Kiss-off hold feature
Kiss-off signal hold until central station receiver software
displays alarm message on screen and printer prints out the message.
Measured response time by running “CT400 alarm receiver software”
after receiving a complete alarm message at one line in CT400 without email
transmission: 20ms maximum without RS232 printer.
45 ms maximum with RS232 printer and
printer baud rate of 115200.
Micro Seven Receiver software
which is included as no charge provided no technical support and no liability
from Micro Seven:
1.
It is Windows
type.
2.
Decode events
and display with date/time
3.
Email
transmissions ON/OFF
4.
Output
displayed data to printer port at another RS232 interface, ON/OFF
5.
Generate
sounds upon receiving alarm messages, ON/OFF
6.
Store decoded
alarm messages in a file
The main screen of the receiver software is
displayed as shown below. The left hand side shows consecutive
received alarm messages from line number (1-4), consecutive alarm message
number, month/date/year/time, complete alarm message, account number, event
qualifier, event code with decoded event, user/zone and partition.
The right hand
side of the screen shows programmed modes for email on/off, printer on/off,
sound on/off and programming data for email transmission, printer and sound.
The decoded alarm messages are saved as history file in computer disk file and also they are transmitted to RS232 printer when enabled.
The screen for
“centralprogram.exe” for programming email, printer, and sound is shown below:
Micro Seven Software/Simultaneous
receiving alarm messages at all lines:
CT400 supports receiving alarm
signals simultaneously at all lines. Received alarm messages are shown in PC
screen and are also archived in “al”. To prove that CT400 can receive alarm
signals at all lines simultaneously, an incoming telephone call is connected to
all four lines. The archived file showed the result below: The first line
indicates that the received line number.
