PROGRAMMABLE ENGINEER OPTIONS
The engineer has all the user programmable options available via the engineer code
(factory default 1234) with the exception of programming the user code (the user code
may only be changed when the user code has been used to access the system).
Additional options (not available if the user code is used to access the system) are
available via the engineer code, these options are shown below:-
Change Engineer Code
This option allows the engineer code to be changed, any four digits may be used but the
dialler will not allow the user code to be duplicated.
Change Trigger Mode
This option allows the trigger polarity to be changed to one of three options, it should be
noted that this option is overridden if Serial Comms is On.
1)
Negative trigger allows the dialler to be triggered by a negative signal.
2)
Positive trigger allows the dialler to be triggered by a positive signal.
3)
Control Panel trigger, this mode allows the dialler to be triggered directly from the
zone inputs and bell output of the Gardtec
350 (or Gardtec 580 without interface)
see Fig4. When used in this mode the Multi-Trigger Inhibit option should also be
turned ON.
The default trigger polarity is negative trigger.
Line Monitor Security Mode
This option allows the security of the line fault monitor to be programmed, the two options
available are shown below:-
Low Security Mode
When programmed this mode monitors the telephone line and will not register a linefault
until the line voltage falls below 4 volts. This mode should be used when the dialler is
being used on a line sharing other equipment.
High Security Mode
When programmed this mode monitors the telephone line and will not register a linefault
until the line voltage falls below 35 volts. This mode should only be used when the dialler
is being used on an exclusive line (not shared by any other equipment).
The default setting is Low Security.
