The front panel view of model AP15 is shown in the above picture. The model AP71 is the same physical characteristics as model AP15.

                                                             RS232                                                     WIRELESS





-Provides a common alarm dialer that may be shared with other applications
-No need to include a telephone dialer in your embedded application
-Wireless operation


Micro Seven Model AP71 with a BLE device is connected by another BLE device like AP72 forming transparent UARTs, and AP71 receives ASCII data, which consist of telephone number to dial, alarm message to transmit, alarm message protocols and other control commands. Status messages that are transmitted back to the other UART includes MESSAGE SUCCESS or CALL FAILED. Type of alarm message protocols include the popular Contact-ID, older Pulse 4X2 or older SIA-FORMAT. Single ASCII command at RS232C interface starts alarm reporting process. After AP71 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, AP71 transmits one of three protocol messages to alarm receiver. AP71 sends status messages back to the UART emulator. If the alarm reporting is not successful, AP71 transmits a different status message. Transmission of alarm messages is repeated for four times if AP71 does not receive positive acknowledge tone. AP71 contains audio monitor internally to hear dialing process, handshake signals, alarm signal transmission, and acknowledge tone/kiss-off tone. Model AP72 with RS232 interface is also available to interface between PC and AP71. Please note that auto dialer in AP70 is not available for AP71.


Wireless standard: IEEE 802.15.1 transparent UART operation, BLE operation

Telephone number: 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.

Alarm message reception 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: AP71 prepares checksum at the end of string for Contact-ID.

Alarm message reception 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 AP71.

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 AP71.

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 AP71:

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>
