1400 +/- 1 Hz with duration of 750 ms

 

Line Input Jacks: USOC-RJ11-C, standard modular phone jack

 

Characteristics for CT10 and CT200:

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.

 

Characteristics for CM10:

Battery-feed voltage and loop current: 24 volt and 25 mA

Programmable inputting telephone number

Dial tone and ring-back tone

Disconnect signal

All other signals required for alarm receivers.

 

RS232C Interface:

Speed: 1200 baud, with one stop bit, no parity bit

The interface signals: Receive Data, Transmit Data, Data Set Ready, Clear-to-send, and ground. The Data Terminal Ready signal is forced high at LS15E+ meaning that a PC is always ready to receive data from LS15E+.

Connector: 9-pin D-sub on LS15E+ the rear panel

Cable(9-pin M/9-pin F) is provided.

Received alarm messages are computed for the checksum.

 

AC/DC Adapter(provided with LS15E+): 117VAC +/- 5%, or 230VAC +/- 5%(for optional 230V AC/DC Adapter)

AC/DC Adapter or Car Battery Adapter input: 12VDC unregulated, 800mA maximum 

Line Status Display: red LED for each line to indicate off-hook status (continuous on) 

Calibration: not required because digitally synthesized tones

Power-On Indicator: green LED display

Dimensions: 19 cm (4") W x 4.5 cm (1.75") H x 10 cm (7.5") L

Weight: 400g (0.8 LBS.)

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.

 

Options and Accessories:

Car Battery Adapter

230V input AC/DC Adapter (117V input unit is a standard.)

Caller-ID receiver option (check with factory for availability)

USB/RS232 adapter cable (virtual RS232 port at PC)

 

Reference: Digital Communication Standard-SIA DC-05-1999.09, Ademco Contact ID Protocol for Alarm System Communications

 

Caller-ID receiver option for CT10 :

  1. It reads FSK caller-ID data between ring signal.  Incoming caller’s telephone number with date/time and names (if available) is generated to PC along with alarm messages at line 2, PBX line input. It supports both single or multiple message formats in Bellcore (US and Canada) and ETS modes. Control characters preceding caller-ID name and telephone numbers may be masked for their output to PC.
  2. It also reads DTMF caller-ID data before ring signal or between ring period. Incoming caller’s telephone number s1, s2, s3,--- is output to PC with the format D(s1)(s2)(s3)----C.

 

Alarm receiving software:

Standard alarm receiver software, that is provided at no charge, “as is” with no support, no liability, and no support from Micro Seven, in Windows operating system that receives and decodes caller-ID information and Contact ID alarm messages displays caller’s telephone number, name, date, nature of alarm messages on PC screen. The software also stores the same information as a text file. Any additional software requirement is custom.

 

We provide no liability using LS15E+ and alarm receiving software to all people and companies including alarm panel users, alarm central station, telephone companies, and all distributors.

 

Other alarm products:

  1. LS15E, LS15E+, Micro Seven, Inc. Alarm Receiver Simulator
  2. AP15, PC alarm panel, RS232 compatible alarm panel
  3. PM10, Alarm panel with excessive sound detection and low/high temperature monitor

 

Typical PC display is shown below: Note that the first line is date/time data that is received from caller-ID, and the date/time on the fifth line is derived by PC. The second and third lines are also from caller-ID. Alarm message number is incremented by each alarm message that is received. The sixth line shows a complete alarm message.

The alarm message file, “al” may be read by another application in a same PC while LS15E+ is running programs. A sample c++ program below open the file “al” and read alarm messages, which must be compared with previous read alarm message file to find out any new alarm message. Note that the file “al” is generated by LS15ES0A.EXE.

The C++ program below uses a timer function to open, read, and close the file “al” periodically to check whether any new alarm message.

 

SetTimer(1,5000,NULL); //timer should be set up somewhere in your program.

//this one is set up for every five seconds, do not set up timer too short

 

void CTest1Dlg::OnTimer(UINT nIDEvent)

{

      hFile2=CreateFile(TEXT("./al"), //open file “al”

        GENERIC_READ,

        FILE_SHARE_READ,

         NULL,

         OPEN_EXISTING,

         FILE_ATTRIBUTE_NORMAL|FILE_FLAG_SEQUENTIAL_SCAN,

        NULL);

 

 ReadFile(hFile2,displaypointer,100000,numberread,NULL); //read an entire alarm message file

 CloseHandle(hFile2); //close file “al”

UpdateData(FALSE);

      CDialog::OnTimer(nIDEvent);
