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. TS900.REM) and an engineer's
interface lead (P/No. NETEKI) which will plug directly
on to the DC58/58M. 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.).

Series Voltage Drop
The voltage drop introduce by the series
connection through the DC58/58M at a line
current of 40mA is 0.1V. When used with other
apparatus (telephone, fax etc.) the total voltage
drop @40mA MUST NOT exceed 2.0V.
Operation
General
When triggered, the DC58/58M seizes the PSTN
line. When a dial tone is detected, it tests the line to
determine if Loop Disconnect (Pulse) or Dual Tone
Multiple Frequency (Tone) dialling is required. (If
the dial tone is not detected within six seconds
then Pulse dialling is automatically selected). The
indicator (LED) is then illuminated. If the unit Pulse
dials the LED will flash as the numbers are dialled.
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
DC58/58M will release the line, and repeat the
process a maximum of three times to each
selected telephone number.
2.
If a Special Information Tone (SIT) is detected,
the DC58/58M immediately aborts the call
and tries again.
3.
When the DC58/58M receives the ID tone it
transmits the appropriate data in fast format. If
the data is successfully received the alarm
receiver responds with an acknowledgement
tone. The DC58/58M releases the line and
flashes the red LED 4 times.
4.
If the acknowledgement tone is not received,
the DC58/58M releases the line and tries
again.
5.
After the third dialling attempt has failed a line
fault is signalled to the control panel to allow
any programmed bell delay to be cancelled.
Special Information Tones (SIT)
These tones are sometimes encountered when
the number dialled is not available or the number
is incorrect. If the DC58/58M detects a SIT it will
immediately abandon the call and try again.
