INTRODUCTION
Micro
Seven Model MicroAP1,
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 from a controller like PC. PC sends ASCII alarm message for
Contact-ID and Pulse 4X2 or Hexadecimal messages to MicroAP1. PC also sends
telephone number to MicroAP1.
After MicroAP1
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, MicroAP1
transmits alarm message. The alarm receiver transmits kiss-off tone if the
message is accepted. Then MicroAP1
sends status messages back to PC. If the alarm reporting is not successful, MicroAP1 transmits a
different status message to PC. Transmission of alarm messages is repeated for
four times if MicroAP1
does not receive kiss-off tone. The whole sequence, which involves re-dialing
of telephone number, may be repeated for three times.
Line
seizure relay is also included for disconnecting house telephone line for
reporting alarm condition.
SPECIFICATIONS
RS232C
interface via external inverters for receiver and transmitter:
9600 baud, no parity, and 8-bit character. No handshakes are provided. RX-N(Inverted Receive Data in TTL signal level) and
TX-N(Inverted Transmit Data in TTL signal level) and RTS-N (Inverted Request To
Send in TTL signal level) are interface signals at the square-pin headers.
RTS-N needs to be driven at TTL high level to hold MicroAP1 transmitting data.
Telephone
number entry for DTMF dialing: D<telephone number-maximum fifteen
digits><CR>
for example D5035551212<CR> for dialing 5035551212. Note <CR> is a
carriage return.
Alarm
message entry for Contact-ID or Pulse 4X2:
S(maximum 15 ASCII characters for Contact-ID or 6
ASCII characters for Pulse 4X2)<CR> for Contact-ID or Pulse 4X2
Note: MicroAP1
prepares checksum at the end of string for Contact-ID.
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 06 23 30 30 30 31 31 31 31 DA FF requires the following:
KD006KD123KD230KD330KD430KD531KD631KD731KD8DAKD9FF.
Note: the ASCII data “DA” is the parity byte of the SIA-FORMAT message.
Another message entry is 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 requires the
following:
S4623303030313131<CR>
Note: The column-parity byte is automatically prepared and attached at the end
of message by AP70.
Protocol selection:
Contact-ID protocol on
power-up default
W7F00 for selecting Contact-ID, W7F01 for selecting SIA-FORMAT, or W7F02
for selecting Pulse 4X2.
Start
alarm message command: 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
MicroAP1
transmits programmed telephone numbers to PC.
Reading
alarm-message command: U
MicroAP1
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 as a default condition:
WACB0
Handshake
tone detection: 1400/2300Hz for Contact-ID, 1400Hz for
Pulse 4X2, or 2225Hz for SIA-FORMAT
SIA-FORMAT
mode:
Signal
transmission of data block for SIA-FORMAT: 110 or 300 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 MicroAP1:
M00<CR>
for successful message transmission
M01<CR> for call failed
M02<CR> for message failed
Note:
<CR> denotes hex D or return character
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>
PCB Mounting holes: 4

Some of demo program may require the auto-dialer option.
Auto dialer programming software for MicroAP1 dialer option is
shown below. Multiple messages are transmitted in one call. Protocol mode,
telephone number and alarm messages are downloaded into MicroAP1 for auto-dialing
mode, which does not require PC for it. The dialer option provides programming
of up to 104 lines. The second window display programs line programming among
lines 24 and 52. Third window and fourth window programs lines 53-81 and 82 to
104 lines respectively. The MicroAP1
dialer software produces history files with real-time data inside PC. The MicroAP1 dialer runs
independently from the MicroAP1
dialer software.
