The 4100ES-S1 Fire Alarm Panel has no provision for load discharge testing of the battery at the
levels required for yearly testing to AS 1851-2005.
A load discharge method separate from the panel must be arranged in order to meet this
requirement. For example, apply an external test load to the battery and operate the 4100ES-S1
with mains power off for 30 minutes. Check the battery voltage at the end of the test.
4100ES-S1 does not include built-in facilities to carry out this test. A suitably rated bench power
supply connected to the battery terminals with main power turned off may be used instead.
Ensure the panel is normal – i.e., no faults and no system conditions that cause the Fault relay to
be re-designed are present.
Reduce the bench power supply output voltage to below the minimum operating voltage and
check the Fault relay de-energises.
If the PSU supervision signal is monitored, confirm that it is received at the monitoring service
or at the main CIE. The status of the PSU/Batt can be observed in the Card Status recalls (refer
Section 9.3). This will indicate Fault condition when the system voltage is below the minimum
operating voltage.
