Overview
General
The DC58M+ digital communicator consists of a
single PCB fitted in a small polycarbonate case. It
is used to transfer fast format status information
from an alarm system to a dedicated Alarm
Receiving Centre (ARC) via the Public Switched
Telephone Network (PSTN). The DC58M+ also
functions as a V21/V22bis modem. The DC58M+
is required when using the up/downloading
feature on compatible Menvier control panels.
Operating Modes
The DC58M+ can be used as a plug-on
communicator, in this mode the communicator is
plugged in to the control panel using the
appropriate connections cable.
NVM Programming
All programmed data is stored in a plug-in NVM
(Non-Volatile Memory) which will be retained for
up to five years with no power present. The NVM
can be programmed by using a Menvier LCD
Remote Keypad (P/No. NETLCD/TS900.REM) and
an engineer's interface lead (P/No. NETEKI) which
will plug directly on to the DC58M+. Alternatively
the NVM can be programmed using the desktop
programmer PP5.
Your ARC will normally provide a programming
service and will supply a pre-programmed NVM
on request or alternatively fill in the programming
form at the back of this manual and return/fax it to
Menvier Security (Repairs Dept.).
Technical Specifications
Supply: 11.5V - 14V; <35mA dc (Standby);
135mA dc (Active)
The installer must ensure that power
drawn by the DC58M+ plus any
other auxiliary apparatus is within
the rating of the control panel (host)
power supply.
Low Battery: Detection threshold is at 10.8V +/-
0.2V
Modem: 300/300 Baud (V21), 2400/2400

Operation
General
When triggered, the DC58M+ seizes the PSTN line.
When a dial tone is detected the DC58M+ lights
the indicator (LED).
1. The appropriate telephone number is dialled,
when answered, the alarm receiver will send a
I.D tone. If no I.D tone is received, the DC58M+
will release the line, and repeat the process a
maximum of three times to each selected
telephone number.
2. When the DC58M+ receives the ID tone it
transmits the appropriate data in the selected
format. If the data is successfully received the
alarm receiver responds with an
acknowledgement tone. The DC58M+
releases the line and flashes the red LED 4
times.
3. If the acknowledgement tone is not received,
the DC58M+ releases theline and tries again.
4. After the third dialling attempt has failed a line
fault is signalled to the control panel to allow
any programmed bell delayto be cancelled.
Three-Way Calling
This is one the new features that is available from BT
Network Services, for this feature to work correctly
the telephone line must have this service enabled
(contact BT for further details). In non-UK countries
you can enabled or disable this feature (as well as
pulse dialling) in programming. See page 9,
Porgramming.
When the DC58M+ is triggered the unit checks for
incoming ringing or off hook (someone trying to
block the call). The unit then sends a "Recall"
signal, which is detected by the exchange as a
request for a new line. With a new line available the
DC58M+ then attempts toconnect with the ARC.
If the DC58M+ is connected to an older pulse dial
only exchange, the numbers being dialled must
be selected to "Pulse" dial, see "Telephone
Numbers" on page 10. This will disable the
three-way calling facility as it is not available on the
older type exchanges.
Line Fault Monitor
The line fault monitor continuously monitors the
PSTN line and will detect:
l
The loss of line voltage (cut line)
l
A line voltage less than 35V (parallel
telephone off hook)
l
An incoming ringing signal that will try and
prevent DC58M+ operation
If the DC58M+ is used on a shared line then the
line fault monitor can be selected to only monitor
a cut line by setting the "HI/LO SECURITY" option to
"LO". It is also recommended that "Three-Way
Calling" is used (see above) so that the security of
the system is not compromised.
Temporary Out of Service
In addition to the line fault monitor, the DC58M+
can be programmed to perform a more detailed
line test at pre-set intervals. The DC58M+ will seize
the line and dial all digits but the last one of
telephone number 1. If the unobtainable tone is
NOT detected it is assumed that the line is healthy
and the unit releases the line. If the unobtainable
tone is detected, a line fault is signalled.
Note: This feature must be disabled if this product
is used in Germany.

Point ID Extended Format
This is a new format which is used to send
additional fast format data to the alarm receiver.
The additional information can be used to
indicate the circuit that caused the alarm, the user
that set/unset the system etc. For the DC58M+ to
send this additional data, the unit must be
plugged on to a Menvier control panel that
supports "Point ID Extended Format"' and report to
a compatible alarm receiver.
Modem
When a call is made to the alarm site the DC58M+
will pick up the call and attempt to connect to the
modem that is connected to the P.C. If successful
the communication link is established and data
can be transferred. When the Modem is on-line
the red LED on the DC58M+ flashes continuously
until the communication link is broken. If during the
Modem operation the control panel generates an
alarm which is required to be transmitted to the
ARC, the DC58M+ will suspend the Modem
operation and attempt to communicate with the
alarm receiver.
Installation

Telephone Numbers
Up to three telephone numbers can be
programmed, each number can be up to 16
digits long. As part of the number, special codes
can be inserted to allow for pulse dialling (P), tone
dialling (T) and a 4 second pause (-) for PABX
systems.
When the DC58M+ dials a telephone number it
will automatically select the correct dialling
format. However, the format can be forced if
required.
Selecting Tone Dialling
Tone dialling is the modern format and is
sometimes referred to as Multiple Frequency (MF)
or Dual Tone Multiple Frequency (DTMF). To force
the number to be dialled in this format press [C]
before entering the telephone number. The
telephone number will be prefixed with a "T" to
indicate tone dialling.
Inserting a Pause for PABX's
If the DC58M+ is connected to an internal PABX
telephone exchange system, normally the
exchange requires a pre-fixed digit to be dialled
before obtaining an outside line (normally 9).
Some exchanges also require a pause after the
pre-fixed digit before dialling the telephone
number. To insert a 4 second pause, enter the
PABX digit (normally 9) then press the [B] key the
display will show "9-". Now enter the telephone
number.
+
When programming telephone numbers it
is very important check that they have
been entered correctly otherwise the
DC58M+ could dial a private number
inadvertently.
Account Numbers
This is a 4 digit number that the alarm receiving
centre uses to identify the alarm site. Up to three
account numbers can be programmed. Account
numbers can only be programmed if the
corresponding telephone number is
programmed i.e., if "Telephone No.2" is blank then
the option to program "Account No.2" is not
available.
Reporting Channels
Each channel can be programmed to report to
any combination of telephone numbers. For
example channel 1 can be programmed to
report to all telephone numbers, whereas channel
3 can be programmed toonly report to telephone
number 1. Reporting channels can only be
programmed if the corresponding telephone
number is programmed i.e., if "Telephone No. 2" is
blank then the option to program "REPORTS TO NO.
2" is not available.
Set/Day Channels
Any channel can be programmed as a '"Set/Day"
channel, this type of channel will report a "Close"
signal when the input channel is active and an
"Open" signal when the input channel is restored.
Normally channel 4 is used to report an
"Open/Close" signal, but if required this can be
changed.
Restore Channels
Any channel can be programmed as a "Restore"
channel, this type of channel will report a "Alarm"
signal when the input channel is active and a
"Restore" signal when the input channel is restored.
If a channel is programmed without "Restore", only
the "Alarm" signal will be transmitted.
+
If any channel is programmed as
"Set/Day", its channel will automatically be
programmed as "Restore".

Programming DC58M+ Installation Instructions
Page 11
Dialling Modes
The DC58M+ can be programmed for the
following Dialling Modes:
Consecutive
In this mode the DC58M+ will dial the first
telephone number and attempt to report the
alarm signal. If the attempt fails, it will shut down
and re-dial the first telephone number. If the
second attempt fails, it will shut down for 1 minute
then re-dial the first telephone number again. If
the third attempt fails the the unit shuts down and
now attempts the second telephone number. This
sequence continues until all three attempts to
each telephone number have been used, after
which the unit will shut down completely.
Alternative
In this mode the DC58M+ will dial the first
telephone number and attempt to report the
alarm signal. If the attempt fails, it will shut down
and dial the second telephone number. If the
second attempt fails, it will shut down and dial the
third number. This sequence continues until all
three attempts to each telephone number have
been used, after which the unit will shut down
completely.
All
In this mode the DC58M+ will dial consecutively,
but also requires a successful communication
from all alarm receivers.
Test Call Period
The DC58M+ can be programmed to periodically
send a "Test" signal (Code 9) to the Alarm
Receiving Centre.
Point ID Extended Format
It is possible to send additional alarm information
to the ARC, this can include circuit and user ID. For
full details on the extended information refer to the
relevant control panel "Installation Manual".
+
This feature is only supported by relevant
Menvier control panels, for details on
which control panels support this feature
contact Menvier Technical Support.
Point ID can be setto one of the following reporting
options:
1 Will NOT Report
This disables "Point ID Extended Format" and
the DC58M+ will only report "Fast Format" data
to the alarm receiver.
2 Limited Report
When "Limited Report" is selected the
DC58M+ will only report the extended format
data relating to the channel that is triggered.
For example, if the DC58M+ is programmed
to report channels 2 and 3 (PA and Intruder)
then the unit will only report events relating to
PA and Intruder activations.
3 Full Report
When "Full Report" is selected the DC58M+ will
report all extended format data to the alarm
receiver irrespective of the channels that are
programmed to report. That is, if all eight
channels are programmed as non reporting,
the unit will still report all events to the ARC.
Temporary Out of Service
This feature is used to test the integrity of the
telephone line by dialling all but the last digit of the
first telephone number. If the unobtainable tone is
NOT detected it is assumed that the line is in good
working order, however, if an unobtainable tone is
detected the DC58M+ will signal a line fault
condition.
+
This feature is only supported by relevant
Menvier control panels, for details on
which control panels support this feature
contact Menvier Technical Support.
