-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 or BT15s
-Compatible to AP15-2 Contact-ID telephone dialer


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.  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 directly to PC via wireless. 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. 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.  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. Operational commands for wireless connection , wireless disconnect and setting up transparent UART operations are also provided.


Wireless standard: IEEE 802.15.1 transparent UART operation, BLE operation employing private address scheme in transparent UART 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.

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:

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.
