MICRO SEVEN, INC.® model
LS15-F and LS15EA-LISTEN-IN
Alarm receiver
for receiving 2-way audio and listen-in and all other alarm codes
For Contact-ID and Pulse
4X2
Copyrights Micro Seven, Inc.®, 2009-2015
LS15F
contains two simulated telephone lines, two FXS ports. LS15EA-LISTEN-IN
contains one regular PBX port (FXO) and one simulated telephone line (FXS). One
line is to receive alarm message, and the other line is to connect incoming
telephone call to a telephone set for 2-way audio. An alarm panel is connected
to Line 1 of LS15F with a piece of telephone cord with no PBX or PSTN line
required. An alarm panel is connected at line 2 of LS15EA-LISTEN-IN via PBX or
PSTN. Received alarm messages are transmitted in ASCII data to PC for
displaying decoded alarm messages by using provided Windows compatible
software. When non-listenin alarm messages are received by LS15F, LS15F or
LS15EA-LISTEN-IN hangs up the received calls. When a listen-in alarm message is
received by LS15F or LS15EA-LISTEN-IN, it will not hang up the received call.
It generates high voltage signal at line 2 for LS15F or line1 of
LS15EA-LISTEN-IN to ring a telephone set. When a receiver of the telephone set
is lifted, a two-way audio path is established between the call from the alarm
panel and telephone set. LS15F may be
configured as a general purpose telephone line simulator as model LS15-C1.

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 LS15F 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 LS15F. The RS232C port of a PC is connected to the
rear panel connector of LS15F with special cable and connector that are
provided with LS15F. Micro Sevens LS15F alarm receiver software decodes
received 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 (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 LS15F 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 LS15F 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 LS15F, it transmits the kiss-off tone to the
alarm panel. LS15F 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 LS15F sees the
on-hook-state, it turns off the loop current for a few hundred milliseconds as a
disconnect signal. Then, LS15F is now ready for a new call from the alarm
panel. LS15F is compatible with the Ademco ® Contact ID Protocol for Alarm
System Communications. Programmed parameters are restored upon powering off and
on unless noted. It also transmits disconnect signal if LS15F does not receive
any more alarm messages for few seconds unless the command was Listen-inE
command type.
If
the received alarm message is Listen-inEcommand, ring signal is produced at a
telephone set at line 2 for two seconds on and four seconds off. When the ring
signal is answered by lifting a receiver of telephone set, 2-way audio circuit
is established between alarm panels speaker/mic and telephone set at line 2 of
LS15F. When either telephone set or alarm panels speaker/mic circuit is hung
up, audio circuit is disabled and both lines in on-hook.
Standard
alarm receiver software, that is provided at no charge, as is with no
support, no liability, and no support from Micro Seven. LS15EA-LISTEN-IN with
FXO port receives alarm messages at FXO interface instead of FXS port in LS15F.
SPECIFICATIONS
Note on special features about
handling listen-in command:
Contact ID Listen-in command with
606 alarm code is received, ring signal is produced at the other line if the
other line is on-hook condition. The hang-up timer is automatically disabled.
Until ring signal is answered by off-hook condition at a telephone set of the
other line, LS15F continues receiving alarm messages and transmitting ASCII
equivalent of alarm messages via RS232 interface to PC. 2-way audio circuit is
enabled between speaker/microphone at alarm panel and the telephone set.
Hanging-up telephone line at either the telephone set at LS15F or alarm panel
resets telephone line conditions at both lines at LS15F. Either line may
receive listen-in command if both lines are enabled as alarm
receivers/simulators using control software except LS15F may receive alarm
signal at one line at a time.
