Micro Seven Model AP20, PC-Alarm Panel or Alarm-Panel Simulator, transmits SIA-FORMAT alarm messages to alarm receivers by starting commands sent at RS232C interface in PC. PC sends ASCII alarm message to AP20. PC also sends telephone number to AP20. Since the alarm messages, telephone numbers, and AP20 Control Register for storing programming parameters are stored in non-volatile memory in AP20, so a single ASCII command at RS232C interface start alarm reporting process. After AP20 dials a telephone number for a receiver, the receiver answers the call and transmits the handshake tones. Then AP20 transmits several data blocks in FSK. If the receiver receives the alarm message with correct column parity with acknowledge requested bit on, it transmits acknowledge tone. AP20 sends status messages to PC. If the alarm reporting is not successful, AP20 transmits a different status message to PC. Transmission of alarm messages is repeated for four times if AP20 does not receive positive acknowledge tone. The whole sequence, which involves re-dialing of telephone number, may be repeated for three times. AP20 contains audio monitor internally to hear dialing process, handshake signals, FSK signals, and acknowledge tone. AC/DC adapter and interfacing cable between PC and AP20 is provided. 220V AC/DC adapter is optional. SIA-Format alarm receiver/simulator, model LS15SIA FORMAT, is recommended for alarm receiver.
RS232C interface: 9600 baud, no parity, and 8-bit character, RTS/CTS hardware handshake
number entry: D<telephone number-maximum fifteen digits><CR>
for example D5035551212<CR> for dialing 5035551212. Note <CR> is a carriage return. It is stored in EEROM (non-volatile memory) in AP20.
block entry: S(data block without column parity byte)<CR>
Note: AP20 prepares column pairty byte.
alarm reporting: G
Start alarm reporting process by dialing the telephone number, receive handshake tones, transmit data blocks, receive kiss-off tones and hang up the line if AP20 Control Register is programmed.
command or Abort command: A
Turn off off-hook relay in AP20 or abort alarm reporting process.
alarm message command: B
It transmits alarm message again.
telephone-number command: T
AP20 transmits programmed telephone numbers to PC.
alarm-message command: U
AP20 transmits programmed data block to PC in hexadecimal notation.
Handshake tone detection: 2225Hz
Signal transmission of data block: 300 baud
Pairty bit (9th bit): enabled/disabled
Wrong column parity: enabled/disabled
Acknowledge tone detection: 2025Hz for positive acknowledgement and 2225Hz for negative acknowledgement
Note: “MESSAGE SUCCESS” messages are also generated when messages do not require kiss-off tones.
Audio monitor: audio speaker is included inside AP20 for hearing dialing process, handshake tones from alarm receivers, FSK signals from AP20, and acknowledge tones from alarm receivers. Audio monitor is to verify that AP20 is calling alarm receivers, and it is a great tool to troubleshoot sending alarm signals to alarm receivers.

The demonstration program, which is available upon request, for using AP20 is shown below with edit windows of entering messages and telephone number. It transmits three data block messages in sequence.
How to send three data block from AP20:
1. Transmit “D18005551212<CR>, for programming of 18005551212 for telephone number
2. Transmit “WACB2" for not to hanging up delivering one message.
Sending address block data by transmitting
“KD006KD123KD230KD330KD431KD531KD631KD731KD8DAKD9FF” for hex codes of
06 23 30 30 31 31 31 31 DA FF
4. Transmit “G” to start dialing and transmit messages.
5. Wait to receive “MESSAGE SUCCESS” from AP20.
6. Sending new alarm block with console emergency “KD044KD14EKD251KD341KD430KD530KD6E5KD7FF” for sending 44 4E 51 41 30 30 E5 FF.
7. Transmit “B” to deliver another data block.
8. Wait to receive “MESSAGE SUCCESS” from AP20.
9. Sending Listen-in command “KD042KD14CKD239KD330KD4F8KD5FF” for hex codes of “42 4C 39 30 F8 FF”
10. Transmit “B” to deliver another data block.
11. Wait to receive “MESSAGE SUCCESS” from AP20.
12. Transmit “A” to hang up the telephone.
