A typical application of
PCBA-001 is shown in a block diagram below:
SPECIFICATIONS
4-pin
header for +5V, GND, tone output, analog input
Handshake tone priority:
Three different handshake signals
are produced sequentially. SIA-FSK handshake, Pulse 4+2 handshake and
Contact-ID handshake are generated sequentially
4+2 Pulse Format supports SIA
DC-02-1992.02, 4.1.3 SIA Pulse Format P3:
Handshake frequency: 1400 Hz
Handshake duration: 1 sec
Data carrier frequency: 1900 Hz
Data modulation rate: 20
pulses/sec
Data inter-digit time: 500ms
Subscriber ID field: 4
Event code: 2
Verification: double transmission
Kiss-off tone frequency: 1400Hz
Kiss-off tone duration: 750ms
minimum
Note: Listen-in feature is always
enabled so that audio from incoming telephone line at either line 1 or line 2.
Audio is also generated at external audio connector of rear panel of
LS15E+/4+2. LS15E+/4+2 does not become on-hook unless incoming line does not
hang up and go on on-hook. Received data in ASCII is output at RS232 interface.
Handshake tones for SIA-FORMAT:
2225Hz:
-20 dBm nominal power, -30 dBm power in the line impairment mode
Kiss-off tones for SIA-FORMAT
(Acknowledge tone):
2025 (positive)
or 2225 (negative), -20 dBm nominal
power, -30 dBm power in the line impairment mode
Alarm message baud-rate for SIA-FORMAT
( input baud rate of alarm message):
110 or 300 baud automatic detection
DTMF detecting
signal power for alarm messages for Contact-ID: -23dBm to +5dBm per a frequency with
maximum 4dB difference between frequencies
Alarm
message DTMF signal on time (Burst ON time): 50 ms minimum
Alarm
message DTMF signal off time (Burst OFF time): 50 ms minimum 400 ms maximum
Note:
Contact ID protocol requires Burst ON and OFF times to be 50 ms minimum and 60
ms maximum.
Handshake tones:
1.
contact-ID: 1400: 1400+/- 1Hz, duration of 100 ms +/- 1.5 ms, silence period of
100 ms +/- 1.5 ms, and
2300Hz:
2300+/-2 Hz duration of 100 ms +/- 1.5 ms
2. 4+2
Pulse: 1400Hz
Kiss-off tones for both Contact-ID
and 4+2 Pulse:
1400 +/-
1 Hz with duration of 750 ms
Kiss-off
and handshake tones amplitude: selectable among -14 dBm, -20 dBm, and -30 dBm by control
software
Call
Progress Tone:
selection of single frequency or dual frequency type selected by control
software
RS232C Interface:
Baud rate: 1200 baud,
with one stop bit, no parity bit
Dimensions: 5”x3”
Environmental: Operating temperature: 0 to 35 degree
C, Humidity: 85% RH at 35 degree C
Warranty/Service: 6 months limited warranty
Options and Accessories:
1. Wi-Fi interface
2. Loop current and dialing signal input
interface
3. Product licensing and OEM product
agreement
Reference: Digital Communication Standard-SIA DC-05-1999.09,
Ademco Contact ID Protocol for Alarm System Communications
Reference for SIA-FORMAT:
Digital Communication Standard-SIA DC-03
Other
programable parameters:
Programming
of kiss-off tone length, kiss-off and handshake amplitude, single
frequency/dual frequency call progress
Parity bit testing:
Disable
transmission of negative acknowledge tone after receiving a wrong parity bit.
The column parity checking is still valid.
Wrong column parity word:
Selects
a wrong starting data pattern instead of hexadecimal FF for column parity word.

Without licensing from Micro Seven, Inc. application and use of PCBA-001 may
not be available for producing alarm receiver simulator/tester Micro Seven
model LS15E+ Triple or other related products.
