4/3 DTMF Format
The 4/3 DTMF format features the advantage of rapid transmission in cases where a large number of reporting codes
need to be transmitted. The 4/3 DTMF Format is compatible with most Sur-Gard digital receivers.
Note that this format
will respond to 2300Hz handshake tones only.
The 4/3 DTMF Format transmits 8 DTMF digits for each event. Each round is transmitted as follows:
AAAA XCC P
Where:
AAAA
is the Account Code
X
is a pre-programmed Event Identifier
CC
is the 2-digit Reporting Code
P
is the checksum parity.
The following Event Identifiers are pre-programmed and will be transmitted before each Reporting Code:
Semadigit DTMF Pager Format
The Semadigit DTMF Pager Format transmits 7 DTMF digits for each event. Each round is transmitted as follows:
AAAA XX C
Where:
AAAA
is the Account Code
XX
is the 2-digit Reporting Code
C
is the DTMF character “#”
This format requires an initial handshake of 440Hz, and a kissoff handshake of 1400Hz.
Semaphone Pager Format
This format communicates no data. The system will call the phone number programmed in Section [30] once for each
event that occurs. This format is intended for use with a pager but can also be used to call a private residence. If ID
Tone is enabled in Section [22], the system will sound a “beep” on the line every 2 seconds after dialing the telephone
number. Although the event is not identified, the recipient of the call is made aware of the alarm.
Private Line Format
Do not use this format with the Printer enabled.
This format will only transmit zone alarms. When a zone goes into alarm, the system will dial the first telephone number
programmed. When the call is answered, the system will sound a double “beep” on the line. The listener receiving the
call will then know that an alarm system is making a call. Pressing 3, 6, 9 or # on a touch-tone (DTMF) telephone will
have the system transmit the zone or zones that are in alarm.
The system will indicate which zone is in alarm by sounding a number of beeps. One beep will sound for zone 1, two
beeps for zone 2, 3 beeps for zone 3, and so on.
When the system has sounded the tones to indicate which zone is in alarm, it will wait for approximately 5 seconds
for the listener to send a closing handshake. Pressing 3, 6, 9 or # will send a closing handshake to the system. When
the system receives the handshake, it will either hang up, or will sound tones to indicate the next zone in alarm.
