Micro Seven Model AP70, PC-Alarm Panel or Alarm-Panel Simulator, transmits Contact-ID, Pulse 4X2 or SIA-FORMAT alarm messages to alarm receivers by starting commands sent at RS232C interface in PC. PC sends ASCII alarm message for Contact-ID and Pulse 4X2 or Hexadecimal messages to AP70. PC also sends telephone number to AP70. Since the alarm messages, telephone numbers, and AP70 Control Register for storing programming parameters are stored in non-volatile memory in AP70, so single ASCII command at RS232C interface starts alarm reporting process. After AP70 dials a telephone number for a receiver, the receiver answers the call and transmits the handshake tones. Depending on which protocol mode that is selected, AP70 transmits one of three protocol messages to alarm receiver. AP70 sends status messages back to PC. If the alarm reporting is not successful, AP70 transmits a different status message to PC. Transmission of alarm messages is repeated for four times if AP70 does not receive positive acknowledge tone. The whole sequence, which involves re-dialing of telephone number, may be repeated for three times. AP70 contains audio monitor internally to hear dialing process, handshake signals, alarm signal transmission, and acknowledge tone/kiss-off tone. AC/DC adapter for 117VAC and interfacing cable between PC and AP20 is provided. International AC/DC power adapter is available as an option. Alarm receiver with FXS and FXO ports, model LS15E+TRIPLE, with all three protocols, Contact-ID, SIA-Format, and Pulse 4X2, is available for your alarm receiver/simulator.


RS232C interface: 9600 baud, no parity, and 8-bit character, no handshakes


DTMF tone frequencies:
Transmitting DTMF tone frequencies at AP15 and AP70 are accurate within -0.027% of the specifications. And their transmitting DTMF tones amplitude is selected for high or low power output level (see AP15 control register below for programming transmission level).

The measured DTMF frequencies for the factory default values are as follows while the standard values are in parenthesis:
 696 Hz (697Hz), 769Hz (770Hz), 851Hz (851Hz), 941Hz (941Hz), 1212Hz (1209Hz), 1334Hz (1336Hz), 1481Hz (1477Hz), and 1633Hz (1633Hz)

In AP70, frequencies of DTMF tones are programmable using new “ap15progV2.0.exe” for +/- 1% to +/- 5%, i.e. The frequency of 697 Hz is adjustable between 662 Hz and 732Hz for eleven steps. The frequency of 1633Hz is adjustable between 1551Hz and 1715Hz for eleven steps. The programming of DTMF tone frequencies allows evaluation of Contact-ID alarm receivers.

Telephone number entry: D<telephone number-maximum fifteen digits><CR>
for example D5035551212<CR> for dialing 5035551212. Note <CR> is a carriage return.
Warning: each telephone number digit must be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, *, #, or , (comma). Note: comma adds two seconds delay between digits.

Alarm message entry for Contact-ID or Pulse 4X2:

S( in maximum 15 ASCII characters for Contact-ID or 6 ASCII characters for Pulse 4X2)<CR> for Contact-ID or Pulse 4X2
Note: AP70 prepares checksum at the end of string for Contact-ID.

Warning: ASCII character for Contact-ID must be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, B, C, D, E, or F. All other character may result in failed transmissions. Please note that ‘A’ is an illegal character for Contact-ID alarm message.

Warning: ASCII character for Pulse 4+2 must be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.  All other character may result in failed transmissions.

Alarm message entry for SIA-FORMAT:
Because alarm message for SIA-FORMAT contains binary number, input requires hexadecimal number. It is memory write command for storing memory address 0D0H or 0xD0. The memory address is 0D0h, 0D1H, 0D2H, 0D3H, 0D4H------. The end of message is indicated by 0FFH.
For example, sending an address block data of 4
6 23 30 30 30 31 31 31 31 requires the following:
Note: The column parity byte is automatically prepared and attached at the end of message by AP70.

New entry format is also available to enter hexadecimal notation with ‘S’ header as follows:

S(hexadecimal two character ASCII) (hexadecimal two character ASCII)-----.
For example, sending an address block data of 46 23 30 30 30 31 31 31 31 requires the following:
Note: The column-parity byte is automatically prepared and attached at the end of message by AP70.

Protocol selection:
W7F00 for selecting Contact-ID, W7F01 for selecting SIA-FORMAT, or W7F02 for selecting Pulse 4X2.

Start alarm reporting: G
Start alarm reporting process by dialing the telephone number, receive handshake tones, transmit data blocks, and receive kiss-off tones.

Hang-up command or Abort command: A
Turn off off-hook relay or abort alarm-reporting process.

Repeat alarm message command: B
It transmits alarm message again. Transmitting alarm messages must be programmed prior to sending this repeat alarm message command.

Reading telephone-number command: T
AP20 transmits programmed telephone numbers to PC.

Reading alarm-message command: U
AP20 transmits programmed data block to PC in hexadecimal notation.

Continuous message transmission mode without turning off telephone relay:
Instead of transmitting single message, multiple messages are transmitted by sending “WACB2”.

Single message transmission mode:

Multiple message transmission mode:

Handshake tone detection: 1400/2300Hz for Contact-ID, 1400Hz for Pulse 4X2, or 2225Hz for SIA-FORMAT


Signal transmission of data block for SIA-FORMAT: 300 baud or 110 baud selectable
Pairty bit (9th bit): enabled/disabled
Wrong column parity: enabled/disabled
Acknowledge tone detection: 2025Hz for positive acknowledgement and 2225Hz for negative acknowledgement.

Messages received from AP70:

Note: “MESSAGE SUCCESS” messages are also generated when messages do not require kiss-off tones.



Status messages: the following status messages are generated at RS232 interface when a control register bit is set:

S00<CR>: telephone relay is on
S01<CR>: begin to dial
S02<CR>: contact-ID handshake signal is detected
S03<CR>: SIA format handshake signal is detected
S04<CR>: 4+2 handshake signal is detected
S05<CR>: transmission of Contact-ID message
S06<CR>: Sequential synch signal transmission
S07<CR>: SIA-FORMAT message transmission
S08<CR>: Pulse 4+2 message transmission
S0A<CR>: hang up telephone line

Debug messages are generated at RS232 interface when a control register bit is set:

The following debug messages are generated after start alarm message command G:
d(telephone number) p (protocol) m(alarm message) <CR>
Example of the Debug message:
After programming telephone number of 18005551212 and contact-ID message of 123418313112345, the following debug message is generated by microAP1:
d18005551212 p00 m123418313112345<CR>
