the other), the panel cannot report to both stations in the „Station 1 or Station
2” mode and will change the option for transmission to the station which has
a larger number of identifiers.
Note: For the Ademco Express transmission format the identifier „0000” is
correct (sending "zero" is possible), while for the other formats it means no
identifier ("zero" is not sent).
A headset connected to the "telephone line monitoring" jack in the SM-2 synthesizer
can be helpful in analyzing the problems with communication to the monitoring
station
Connection with the station is established in the following way:
• the station answers the call and sends the, so-called, handshake signal (one
or a few in sequence if the station supports several transmission formats),
• the control panel recognizes the station handshake signal and if it matches the
programmed transmission format, the control panel answers by sending
identifier and event code in appropriate tones (once or twice, depending on
the selected format) – in the headset connected to the line monitoring jack,
these sounds are much louder than the monitoring station signals,
• if the station receives information, it will acknowledge it with the same signal
as the handshake,
• the panel disconnects or sends next codes if there still are some other events
to be reported to the station.
The most common monitoring problems result from inaccurate information on the
transmission formats supported by the given station (e.g., ambiguous names of the
formats), errors in the data entered into the control panel, as well as poor quality of
the telephone connections. Often only by “monitoring” the course of communication
you are able to find the cause of a problem.
NOTE: Some stations do not acknowledge reception of the event code if it has
another format (e.g., 4/1 instead of the required 4/2). If this is the case, the control
panel will repeat its attempts to establish communication, while telephones in the
facility will be disconnected - the costs of such connections may be very high. For
this reason, it is recommended that all the programmed codes be very carefully
checked. It is possible to activate the options 7 and 8 in FS-47, which makes the
panel omit the codes unacknowledged in 16 consecutive retries. Problems of this
type do not occur in professional, multi-format monitoring stations (including the
Satel STAM-1).
Downloading - Telephone Communication with the Computer
Telephone communication with the computer requires a modem. The modem must
meet two essential conditions:
1. enable operation in the transmission format UTI V.21 (CCITT V.21) or BELL
103 (operation at a rate of 300Bps on telephone line),
2. permit operation to be configured only in one of these formats (the function of
automatic format negotiating disabled).
Before starting the first connection between the computer and the control panel,
appropriate settings must be entered in the DLOAD10 program (CONFIGURATION
window). Information on the modem configuration is contained in the DLOAD10
program „HELP” file (function activated with F1 key), topic: COMMUNICATION” and
in chapter “PROGRAM CONFIGURATION FOR COMMUNICATION WITH THE
PANEL” of this manual. In the case of non-standard modems, you must refer to the
modem manual for the information on configuration procedures.
