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. There is an configuration option for adding protocols for BFSK14, BFSK13, 3/1 14, 3/1 23, SK 4+2, SIA P1, SIA P2, SIA P3, and SIA P4.

SPECIFICATIONS

Output formats: Micro Seven format for interfacing Windows Central Station software included.

Handshake tone priority:

Unless 4+2 pulse and SIA-FORMAT are individually disabled by the control software, handshake tone for SIA-FORMAT is generated first. . If there is no signal received for SIA-FORMAT, handshake tone for 4+2 is generated. Then finally if there is no signal received by LS15E+/4+2, handshake tone for Contact-ID is generated.
