There are new battery tests and battery/mains/charger monitoring options that were
not available in the older software. These are as follows.
Battery connection test
Hourly 90 second battery test
Daily 40 minute battery test
Battery low monitoring
Charger high/low fault signalling
Mains fail signalling fault after 8 hours.
These options are accesse
d via Menu 3 ► ► 3, and all but the last option need to be
enabled to comply with AS4428.1. If the daily 40 minute battery test is enabled then it
is essential that the battery test resistors R52/R53 (if present) on the MAF module be
removed.

The mapping of zones to ANC 1 relay, Warning System, and the External Bell needs
to be carefully checked. Zones previously mapped to ANC 1, ANC 2, and ANC 3
become mapped to ANC 1, Warning System, and External Bell, respectively, when the
database is converted to AS4428.1 mode by the database conversion utility. I.e. a
zone which previously mapped to ANC 2 will now be mapped to the Warning System
(which by default uses ANC 3) and a zone previously mapped to ANC 3 becomes
mapped to the External Bell (which by default uses ANC 2). Therefore, on upgrading,
it is likely that the output wiring from ANC 2 and ANC 3 will need swapping over and
changes made to the wiring to allow supervision.
If the ANC 2 relay is not going to be used for either the Warning System or the
External Bell, but is still required to operate for an alarm on zones that were previously
mapped to it, then those zones will need to have their mapping to the Warning System
removed (unless they also need to operate the Warning System) and a logic equation
should be entered to drive ANC 2 directly from the zone alarms, or from the ALM token
if the ANC 2 relay should operate for any MAF alarm.
Similarly with the ANC 3 relay, some systems may need to remove the mapping of
zones to the External Bell (these are zones which previously mapped to ANC 3) and
enter a logic equation for AR3. If the ANC 3 relay is actually used to drive the External
Bell then the zones which previously mapped to ANC 3 will have become mapped to
the External Bell and this can be left unchanged, but it will be necessary to enter an
equation for the External Bell to drive AR3 e.g. AR3 = EBO + EBT
6. The Ancillary 1, 2, 3 relays can be configured as latching/non latching; mapped to maf;
isolatable/non-isolatable etc and they can all be configured with a text name. For
AS4428.1 compliant systems, the Warning System and External Bell outputs must be
supervised.
7.
Mapping of the Warning System/ External Bell to MAF.
It is recommended that these be enabled (Menu 4 3 2 ) so that isolate conditions are
signalled to a monitoring centre (refer section 7.4.3).
8.
The are some new "FF options" settings that should be checked. Refer to section
6.4.4.1.
