Preliminary information with subject to change

Copyrights Micro Seven, Inc.®, 2016

LS15E1 contains one simulated telephone line/FXS port for interfacing Contact-ID alarm panel. LS15E1 provides all necessary electrical signals for alarm panel including detecting dial tone, dialing telephone numbers, providing handshake signal and kiss-off tone. LS15E1 receives Contact-ID signals from alarm panels, and transmits ASCII equivalent characters of the received signal to PC via RS232 interface. A demo central station software displays decoded alarm messages. Bi-directional signal paths between LS15E1 and alarm panel may be attenuated for 20dB by provided Windows based control software. Random noise may also be injected to bi-directional signals with its amplitude adjusted also by the control software. Trigger signal for loop is located at Line 2 connector.

SPECIFICATIONS

Telephone number receiving: any telephone number with dialed number display output using the control software

DTMF dialing signal power: -13dBm to +5dBm per a frequency with maximum 4dB difference between frequencies.

Pulse dialing: Break period: 45 to 75 ms (60 ms nominal), make period: 30 to 60 ms (40 ms nominal)

DTMF detecting signal power for Contact-ID alarm messages: -23dBm to +5dBm per a frequency with maximum 4dB difference between frequencies as a factory standard, the DTMF detection threshold programmable by the control software

Alarm message DTMF signal on time (Burst ON time): 50 ms minimum

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.

Detailed DTMF on/off timing received alarm panels are displayed in the PC screen i.e. 50 for 50ms 99 for over 99ms

Received DTMF signal amplitude data is displayed on screen.

Handshake tones:

As a factory standard:

1400: 1400+/- 1Hz, duration of 100 ms +/- 1.5 ms, silence period of 100 ms +/- 1.5 ms, and

2300Hz: 2300+/-2 Hz duration of 100 ms +/- 1.5 ms

Frequencies of handshake signal are programmable for +/- 20% using the control software. Also duration of handshake tone is programmable.

Kiss-off tones: 1400 +/- 1 Hz with duration of 750 ms as a factory standard. The duration of kiss-off tone is programmable between 10ms and 2.5seconds.

Frequency is programmable for +/- 20% using the control software.

Programmable delay time in second between received good Contact-ID messages and generation of kiss-off tone. The range is between 0 and 10 seconds.

Kiss-off generation hold off feature is available using the control software.

Kiss-off and handshake tones amplitude: selectable among -14 dBm, -20 dBm, and -30 dBm by control software as a factory standard

Programmable-between –6 dBm and –40 by the control software

Bi-directional signal paths: insertion losses are 0 or 20 dB. Random noise is added to each signal path for –10 dBm and –60 dBm.

Line impairment condition may be selected among the following three different simulated telephone line:

1. simulating ideal telephone circuits
2. 20 dB insertion loss
3. 20 dB insertion loss and random noise injection

Battery-feed voltage (loop voltage): -20 volts

Off-hook impedance requirement: 400 ohms maximum DC, 600 ohms nominal AC

Call Progress Tones: single frequency or dual frequency type selected by control software

The duration of disconnect signal is programmable.

Stutter dial tone: selected by control software

Dry-contact output is at line 2 jack for center pins for tripping alarm loop via software control and RS232. The output is selectable Normally Open or Normally Closed.

Front panel control:

Power switch

Power indicator

Line 1: RJ11 connector for alarm panel input (FXS)

Line 2: dry-contact for loop input.

Line Status Display: red LED to indicate off-hook status

Rear panel control: RS232 connector, power connector

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 LS15F meaning that a PC is always ready to receive data from LS15F.

Connector: 9-pin D-sub on LS15F the rear panel

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

Received alarm messages are computed for the checksum.

AC/DC Adapter: 117VAC +/- 5%, or 230VAC +/- 5%(for optional international AC/DC power adapter)

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

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.

Option:

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

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