 Copyrights Micro Seven, Inc. ® 2010


Micro Seven, Inc. model LS100-2E contains both dtmf-Alarm-Receiver Simulator and PBX simulator/telephone-line simulator functions. The Alarm-Receiver Simulator function provides simulated telephone-line and alarm receiver for bench-testing alarm panels for dtmf-based protocol including 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 LS100-2E provide 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. Selections of handshake tones, kiss-off tones, alarm message length, enabling/disabling checksum, kiss-off tone hold, enabling 2-way audio by listen-in command, handshake tone length are provided with Windows-based control software. LS100-2E provides testing of alarm panels for many types of dtmf-based alarm message formats including popular Ademco Contact-ID.

Telephone-line simulator function simulates two dial-up telephone lines for testing and demonstrating telecommunication equipment. When a correct telephone number is dialed at line 2, ring signal is produced at line 1. When the call is answered at other line, bi-directional signal paths are established between two lines. The telephone-line simulator features are very similar to ones in LS100-2A. Many features include 30HZ square-wave ring signal, dual frequency and single frequency call progress tones, switching extra 20 dB signal attenuation on/off, primary and secondary telephone numbers, stutter dial tone, PBX mode, hot-line mode, distinctive ring, network delay, and disconnect signal.

4+2 protocol option provides receiving and displaying alarm messages with SIA pulse format.

Operation of alarm-receivers

Traditionally, when alarm panels are tested in the manufacturing, an alarm receiver with telephone lines is required. The Micro Seven model LS100-2E provides both simulated telephone lines and alarm receiver in a box so that your alarm panels are connected directly to LS100-2E. The line 1 and 2 of LS100-2E are designated as an alarm receiver and telephone line simulator respectively.

Connect your alarm panel to the RJ11 connector at line 1 of LS100-2E with a regular telephone cable.  The connection of serial interface cable between LS100-2E and PC is optional. If it is connected and the software is executed, further decoded alarm messages are displayed on PC screen. Even emails may be generated automatically.

Create an event at your alarm panel to report alarm condition. When your alarm panel goes off-hook, “OFF-HOOK SIGNAL” and “DIAL-TONE ON” are displayed on LCD displayed on LS100-2E.

Note: actual display area is 1”(2.5cm)x2.75”(7 cm).




When the alarm panel is dialing a telephone number such as a toll-free 1800-555-1212 for your alarm panel, “DIALING” and “18005551212” is shown on the LCD display. LS100-2E accepts any telephone number for alarm receiver function unlike correct telephone numbers are required to be dialed at a line when the line is programmed as a telephone line simulator not as an alarm receiver. Since the alarm receiver is internal, there is no ring signal generated.



LS100-2E waits one second at the end of dialing process. Then it generates ring-back tone at the line displaying “RING-BACK TONE” on the LCD display. There are two ring-back tone periods.


Then LS100-2E generates the handshake tones with 1400 and 2300 Hz displaying “HANDSHAKE TONES” on the LCD display.




Then your alarm panel transmits sixteen-digit digital alarm message to LS100-2E.

There are two displaying modes. One mode displays raw sixteen-digit alarm messages on the LCD display. The other mode displays decoded alarm messages including alarm code, description of alarm code, account number, new/restaural/status, zone, and partition number.

The raw message mode displays “KISS OFF/MESS.RECV” and “567818111012223” on LCD display. If it is the decode message mode, the display is “110 Fire Alarm” and “A:5678 New/Open”. Where 5678 is account number and the “New/Open” is the type of message. The display may also be either “Rest/Clos”  for 3=New Restore or Closing/or “ or Status Rp” for 6=previously-reported condition still present (Status report). 

KISS OFF/MESS.RECV             


110 Fire Alarm
A:5678 New/Open

The bottom portion of the display is then changed to : “P:12 ZON/USR:222” which indicates the partition=12 and the zone=222. The bottom portion of the display changes for every second between the account number with type of message and partition with zone numbers. The decoded messages of event codes that are stored in EEPROM inside LS100-2E may be edit by any text editor, and the changes may be downloaded to LS100-2E by special software. Twelve maximum characters for each event code is displayed at 16x2 LCD module.

110 Fire Alarm
P:12  ZON/USR:222


Maximum twelve characters are only displayed on the above LCD display for a decoded event code.

If there was no alarm message received and LS100-2E goes on hook, it display “ON-HOOK” shown as below.

If the checksum in the alarm message is wrong, the “BAD MESSAGE" is shown as below with the received message.


Specifications for alarm receiver function:

Dialing into alarm receiver: It accepts any numbers of any DTMF digit, but the maximum pause time between digits should be less than one seconds. The maximum dialing digit is sixteen. Dialed numbers are shown in the LCD display.

Alarm message detection signal power:
-13 dBm to +5 dBm per a frequency with maximum 4 dB different between frequencies at the RJ11-C connector

Handshake tones:

Kiss-off tones:
1400 +/- 1 Hz –20 dBm nominal power, -30 dBm power in the line impairment mode with duration of 750 ms

Alarm receiver software: Window-based software is provided with LS100-2E for further decoding alarm messages with date/time information. Also, all received alarm messages are stored in a disk file as continuous file. The software may be able to transmit emails into Internet when alarm messages are received at PC. All communications via PC are done at RS232 interface.

Control software that is provided: ls1002e.exe for the following:
1. selection of alarm receiver or telephone line simulator for each line
2. selection of LCD display modes between raw alarm message and decoded alarm message

2-way audio and listen-in command: If the listen-in command with alarm event code of 606 is received by LS100-2E, no subsequent alarm messages are received. Ring signal is generated at other line in LS100-2E. Ring-back tone is generated at the alarm panel. When the call is answered at the line, voice paths are established between the other line and alarm panel in 2-way audio path. The hang-up timer is disabled.
