Micro Seven®, models LS15P, cONTACT-id aUTOMATIC tESTER for comprehensive automatic production testing of alarm panels without needs of alarm sensors, also includes digital alarm receiver testing as an optional feature
copyrights Micro Seven ®, 2014
-complete testing of alarm panels for Contact-ID protocol.
-PC-controlled automatic testing of alarm panels
-no need of loop sensors. The loop trigger circuit is already built-in. When “start” button is pushed on PC, a loop is tripped and alarm signal is generated automatically.
-includes comprehensive DTMF tone detector which generates received DTMF signal strength data for low and high frequency components in DTMF tones.
-independent DTMF tone detection level for dialing or Contact-ID alarm messages
-single shot or continuous testing by PC
-optional software feature for sending email alert of testing failures
-history file of test conducted with real-time data is created in PC.
-Made in U.S.A.
-LS15P with RS232 interface or LS15P1 with Ethernet interface
-Tester for Contact-ID alarm receiver is optional feature.
Automatic testing of your alarm panel using PC and Micro Seven ® model LS15P is available in the block diagram shown above. Automatic software in PC with RS232 interface or RS232 interface with USB adapter provides single-shot or continuous testing of your alarm panel with Contact-ID protocol. The alarm-panel test is started by loop trigger signal from LS15P. Loop input indicates an alarm condition. Your alarm panel dials a preprogrammed telephone number at a telephone line output after receiving loop current and dial tone. LS15P either compares with pre-programmed telephone number or accepts any telephone number. LS15P generates ring-back tone and handshake signals. Your alarm panel transmits Contact-ID messages in DTMF. LS15P generates kiss-off tone to your alarm panel after computing checksum from received alarm messages. LS15P outputs received alarm messages and received DTMF signal levels in ASCII formats to PC for display. Single-shot or continuous test may be performed. DTMF threshold levels for dialing and Contact-ID alarm messages may be programmed independently by programming software. LS15P contains all features of model LS15e+ Dialer, http://www.microseveninc.com/broch15e+4x2.htm except line2, the FXO interface, is disabled when the automatic test function using the loop trigger circuit. Number of LS15Ps may be connected to PC with each RS232 interface with each interface running with LS15P.EXE. Two multi-port test systems for LS15P with RS232 and LS15P with Ethernet/Internet interface are shown in Figure 1 and Figure 2 respectively.
A screenshot of programming software, WLS15E+.EXE, is shown below:
Here dialed telephone number is compared with several programmed telephone numbers or any telephone number may be accepted by enabling “ACCEPTS ANY PHONE NUMBER”. DTMF threshold for dialing number and Contact-ID alarm messages are independently programmed. Kiss-off and handshake tones are independently programmable in term of mili-second may be programmed. Handshake and kiss-off tone signal power may be chosen in three different signal levels.
A screenshot of PC operational software, LS15P.EXE, is shown below:
The DTMF signal analyzer shows DTMF signal strength of low frequency group for 697Hz, 770Hz, 852Hz, and 941 Hz and high frequency group for 1209Hz, 1336Hz, 1477Hz and 1633Hz in dual frequency multi-frequency (DTMF) signal of alarm signal and dialing signal. The value shown for DTMF signal strength is a 16-bit binary number in four hexadecimal notations.
The screenshot of multi-line, IP-based, LS15P1.EXE is shown below: five alarm panels are being tested simultaneously, and test results are transmitted to PC via Internet/Local Ethernet. Continuous loop trigger of alarm panels by LS15P1 starts alarm signal reporting by alarm panels without PC. Test results including error counter and history files are available locally or remotely for PC. Edit window for IP address/IP name uses numerical IP address such as 192.168.254.42 or name/dynamic name such as email@example.com. Dynamic name is updated for external IP address for dynamic IP address with Dynamic DNS service automatically. Test status/test result window shows the latest test result including dialed telephone number with DTMF amplitude indicator, received Contact-ID alarm messages with DTMF amplitude indicator, and test result/status messages.
1. LS15P (RS232) or LS15P1 (Ethernet)
2. Multi-loop trigger option for various alarm inputs
3. International AC/DC power adapter for input power of 90-250VAC with four different power plugs (US/Japan, Europe, Australia and UK)
4. USB/RS232 adapter
5. Alarm receiver option to send Contact-ID alarm messages to a Contact-ID receiver at FXS interface at line 1 that generates ring signal, detecting handshake signal, transmits Contact-ID alarm messages and receives kiss-off tone. Instead of call originating at FXS interface at line 1, it can dial telephone numbers at FXO interface at line 2, detects handshake signal, transmit Contact-ID alarm messages and receives kiss-off tone. Detecting threshold for handshake signal and kiss-off tone are programmable similar to alarm panel testing.
