contact with the control unit for more than 15 minutes. If a detector loses
contact for more than two hours the control unit raises an alarm (see Com-
mand 128).
If you select option 0 the control unit will report supervision failure as de-
scribed for Command 128.
Number of Digits in Access Codes (Command 56 (9752 only) )
The 9752 control unit can use either four-digit or six-digit access codes. To
select four digit access codes choose option 0. Select option 1 for six digit
access codes.
Note: Changing from four- to six-digit access codes (or from six- to four-digit access
codes) causes the system to revert to factory defaults for all access codes. Six
digit user code default is 123456 and Engineer code default is 567890.
Battery Load Test (Command 57 (9752 only) )
Use this Command to make the control unit regularly test its backup battery.
Option 0 The control unit does not load test the battery at all.
Option 1 The control unit tests the battery when the system is unset or 23
hours after the last battery test (whichever comes first).
If the battery fails a test then the control unit reports to the central station.
The control unit also gives a regular short tone from the keypad sounders,
and the keypad shows the message “Batt Load Fail”.
Day Tamper Indication (Command 58 (9752 only))
Use this Command if you want the Engineer to reset tamper indications that
occur while the system is unset.
Option 0 The user can reset a displayed tamper while the system is unset.
Note: Use Command 38 to allow the user to reset the system after
a tamper alarm.
Option 1 The Engineer must reset a displayed tamper while the system is
unset. Note that the user can continue to set and unset the system
while a tamper is being displayed.
Sounder Tamper (Command 59)
The control unit can connect to external sounders with one of two tamper
arrangements:
Option 0 The external sounder uses negative voltage tamper return.
Option 1 The tamper return to the external sounder is terminated with a
2K2 resistance.
Select the appropriate option for the sounder fitted to the system.
