-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
-Hook up to multiple BT10s


In Figure 1, Micro Seven Model BT15 is connected in wireless circuits to another BLE device like BT10, Alarm Panel to Wireless interface unit, BT15 receives alarm messages. Telephone number is stored in EEROM inside BT15. BT15 operations are shared for many BT10 devices.

In another application of BT15 in Figure 2, Micro Seven Model BT15 with a BLE device is connected by another BLE device like BT0 forming transparent UARTs, and BT15 receives ASCII data, which consist of telephone number to dial and alarm message to transmit. 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 BT15 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, BT15 transmits one of three protocol messages to alarm receiver. BT15 sends status messages back to the UART emulator. If the alarm reporting is not successful, BT15 transmits a different status message. Transmission of alarm messages is repeated for four times if BT15 does not receive positive acknowledge tone. BT15 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 BT15. Operational commands for wireless connection , wireless disconnect and setting up transparent UART operations are also provided.

SPECIFICATIONS for a general purpose wireless telephone dialer from PC in Figure 2:

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 receiving:
S( in maximum 15 ASCII characters)<CR>
Note: BT15 prepares checksum at the end of string for Contact-ID.

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

Messages received from BT15:

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>
