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 and 4+2 pulse format protocols. 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 handshake tones for both 4+2 pulse and Contact-ID formats.
The 4+2 pulse format includes features for SIA DC-02-1992.02 (R2000.05) 4.1.3
SIA Pulse Format P3. As a contact-ID
alarm receiver, 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. Alarm receiver software for contact-ID method is provided.

Introduction of Contact-ID alarm receiver
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.
SPECIFICATIONS
Handshake tone priority:
Handshake tone for 4+2 Pulse format is generated
first. If there is no signal received by LS15E+/4+2, handshake tone for
Contact-ID is generated.
