Micro Seven, Inc. model LS15-E+ contains Alarm-Receiver Simulator/Tester and alarm receiver. The Alarm-Receiver Simulator/Tester function provides simulated telephone-line and alarm receiver for testing and demonstrating alarm panels for the Ademco® (registered trade mark by ADEMCO Group, a division of Pittway) Contact ID Protocol. The simulated telephone-line functions include generation of dual-frequency-type dial and ring-back tones, detection of DTMF and rotary-pulse dialing pulses, and battery-feed function. The LS15-E+ provides functions of generation of handshake tones and kiss-off tones, receiving alarm messages, check-sum calculation, and transmitting alarm messages in ASCII format at RS232C interface to a PC. It operates with an AC adapter that is provided with LS15-E+. An alarm panel may be connected directly bypassing telephone companies at line 1 or may be connected to telephone lines at line 2. The Alarm-Receiver Simulator function is available at line 1, and regular alarm receiver function is available as CPE port at line 2. Caller-ID receiver is available for its option in Bellcore and ETS caller-ID standard. Alarm receiver software is provided.

Introduction

 

Traditionally, when alarm panels are tested in the manufacturing or demonstrated in the sales offices, alarm receiver with two public telephone lines are required in addition to a computer. The Micro Seven model LS15E+ eliminates an alarm receiver and two telephone lines by combining both of telephone line simulator and alarm receiver functions for the application. Here, an alarm panel is connected to the line 1 of LS15E+. The RS232C port of a PC is connected to the rear panel connector of LS15E+ with special cable and connector that are provided with LS15E+. Micro Seven’s LS15E+ control software provides a tool to display incoming alarm messages. First, the alarm panel goes off-hook at line 1. The loop current is flowing at the line 1.  Then, the alarm panel dials either primary telephone number “2” (single digit) or secondary telephone-number that is assigned for line 2(programmable one) depending on which telephone number scheme is selected. When the dialed number is correct, the LS15E+ provides ring-back tone for two seconds. Then, there is no sound for four seconds. And ring-back tone is generated for two seconds. After 0.6 seconds, the LS15E+ transmits handshake tones of 1400 and 2300Hz for 100 ms each separated with 100 ms silence period. When the alarm panel receives the handshake tones, the alarm panel transmits a string of alarm message in DTMF tones with a check-sum at the end. When the alarm message with correct check-sum is received by LS15E+, it transmits the kiss-off tone to the alarm panel. LS15E+ also transmits the ASCII equivalent of the alarm message at the RS232C interface to the PC. Then, the alarm panel either transmits a new alarm message after a short delay or hangs up with the telephone line to terminate the call. If the alarm panel did not receive the kiss-off tone, the alarm panel may repeat transmitting the same alarm message four times. When LS15E+ sees the on-hook-state, it turns off the loop current for a few hundred milliseconds as a disconnect signal. Then, LS15E+ is now ready for a new call from the alarm panel. LS15E+ is compatible with the Ademco ® Contact ID Protocol for Alarm System Communications. Programmed parameters are restored upon powering off and on unless noted.

The line 2 of LS15E+ contains CPE (customer provided equipment) circuit to interface PBX inside line. If there is ring signal input at line 2, an off-hook relay is turned on to represent off-hook condition. After short time delay, LS15E+ transmits handshake tones of 1400 and 2300Hz in 100 ms each separated with 100 ms silence period. The rest of alarm receiver sequence is the same as for line 1 as follows: when the alarm panel receives the handshake tones, the alarm panel transmits a string of alarm message in DTMF tones with a check-sum at the end. When the alarm message with correct check-sum is received by LS15E+, it transmits the kiss-off tone to the alarm panel. LS15E+ also transmits the ASCII equivalent of the alarm message at the RS232C interface to the PC.  Then, the alarm panel either transmits a new alarm message after a short delay or hangs up with the telephone line to terminate the call. If the alarm panel did not receive the kiss-off tone, the alarm panel may repeat transmitting the same alarm message four times. When the alarm panel hangs up the call, it produces disconnect signal that interrupts loop current at line 2. Then, LS15E+ turns off the off-hook relay. Then, LS15E+ is now ready for a new call from the alarm panel. LS15E+ is compatible with the Ademco ® Contact ID Protocol for Alarm System Communications. Programmed parameters are restored upon powering off and on unless noted.

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.

Control software operation for alarm receiver

 

ASCII equivalents of all DTMF signals received at alarm monitor are output at the serial port of LS15E+, and it is displayed on the screen when the control software is run no matter the checksums are correct or not. When checksum of incoming DTMF signals is correct, kiss-off tone is output at the telephone jack for line 1 or line 2. Key strokes on key board are transmitted to LS15E+ for programming LS15E+. Character echoing by sending RETURN  between PC and LS15E+ is utilized for the handshake signal.

 

Caller-ID receiver option:

  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.

 

A 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);

}
