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 LS15 SIA FORMAT 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 LS15 SIA
FORMAT. The RS232C port of a PC is connected to the rear panel connector of
LS15 SIA FORMAT with special cable and connector that are provided with LS15
SIA FORMAT. Micro Seven’s LS15 SIA FORMAT 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 a telephone number, which is output at
RS232. After few seconds, the LS15 SIA FORMAT provides ring-back tone for two
on/off periods. Then, there is no sound for four seconds. And ring-back tone is
generated for two seconds. Then handshake
tone is generated by LS15 SIA Format. When the alarm panel receives the
handshake tones, the alarm panel transmits a string of alarm message. When the
alarm message with parity bits and column parity, LS15 SIA FORMAT the kiss-off
tone to the alarm panel. LS15 SIA FORMAT also transmits the ASCII equivalent of
the alarm message at the RS232C interface to the PC. If the alarm message is the Listen-in type, ring signal is
produced at line 2. If a telephone set is attached at line 2 and the receiver
is lifted, 2-way audio paths are established between alarm panel and line 2.
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 several times. When LS15 SIA FORMAT
sees the on-hook-state, it turns off the loop current for a few hundred
milliseconds as a disconnect signal. Then, LS15 SIA FORMAT is now ready for a
new call from the alarm panel. LS15 SIA FORMAT is compatible with the SIA DC03
specifications. LS15 SIA FORMAT also contains a partial capability of LS15-C1,
which is a new generation 2-line telephone line simulator with non-volatile
program memory.
Specifications
of alarm receiver function:
Line 1: alarm
receiver (by factory default), may be changed to telephone line simulator by
control software
Line 2:
telephone line simulator
Dialing: any number
by DTMF or rotary pulse dialing. ASCII equivalent of dialed telephone numbers
are output at RS232:
For
example, if an alarm panel dials 18005551212, the following data is output at
RS232 interface:
#18005551212
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)
Handshake
tones:
2225Hz:
-20 dBm nominal power, -30 dBm power in the line impairment mode
Kiss-off
tones (Acknowledge tone):
2025
(positive) or 2225 (negative), -20 dBm
nominal power, -30 dBm power in the line impairment mode
Alarm
message baud rate: 300 baud
Battery-feed
voltage
(loop voltage): (same as the telephone line simulator function): -20 volts
Off-hook
impedance requirement: 400 ohms maximum DC, 600 ohms nominal AC(same as the
telephone line simulator function)
Call Progress
Tones:
(same as the telephone line simulator function)
Line Input
Jacks:
USOC-RJ11-C, standard modular phone jack (same as the telephone line simulator
function)
Programmable
disconnect-signal: (same as the telephone line simulator function)
The
interface signals: Receive Data, Transmit Data, Data Set Ready, Clear-to-send,
and ground. The Data Terminal Ready signal is forced high at LS15 SIA FORMAT
meaning that a PC is always ready to receive data from LS15 SIA FORMAT.
Special
cable and special connector-9-pin (F)-D-sub at a PC
Received
alarm messages are computed for the checksum, and they are transmitted to PC
for each character. PC transmitted back hex D (carriage return) to LS15E to
signal reception of data.
International
AC/DC Adapter(provided with LS15 SIA FORMAT): 100-240VAC input with four
AC/DC
Adapter or Car Battery Adapter input and 12VDC regulated output, 800mA
maximum

(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

Reference: Digital Communication Standard-SIA DC-03
The provided software is a Window’s
type. Its purpose is to program to control tones and display formats.
Communication port
setup
The
current communication port is displayed. If displayed communication port does
not match with communication port in the computer, “?” is shown in the status
display area. Then enter a new communication port number in the edit window of
RS232 Commport Number. Exit and reenter the software.
The
communication port status, dialed telephone number and alarm messages are
displayed in the edit window.
Alarm
messages are shown in hexadecimal notation of a byte; “30” for ASCII “1”, “41”
for ASCII “A”, etc. instead of ASCII characters.
Parity bit testing
Disable
transmission of negative acknowledge tone after receiving a wrong parity bit.
The column parity checking is still valid.
Selects
a wrong starting data pattern instead of hexadecimal FF for column parity word.
If
you move your cursor to this KB input area, all KB entries are transmitted to
LS15SIA FORMAT via RS232. It simulates Hyper terminal. It is convenient feature
for accessing data memory and EEROM.
Factory
default condition is restored with a file DEF15S. It takes one minute. The
ASCII “D” is shown in the display area
when it is done.
