Response to PCCE ‘Past-Pupil’ Query

March 27, 2020Requirement for 2nd full-duration Test on Commissioning – Self-Contained and CPS Systems
Over the last number of courses I have given I have been concerned that a large number of
experienced EML Commissioning parties are not aware of the requirement (introduced in
2013) that initial system commissioning requires:
A full duration test (3-hour duration on most systems)
A battery recharge period of not more than 24hrs.
**A second full duration test within 24 hours of the initial test, and verification that all
LEDs and EML Signage is functional**
This second test is the only way that it can be proven that the batteries will fully recharge. A
battery could quite easily pass the initial 'full-duration' test but there is absolutely no
guarantee that it will recharge sufficiently to be able to do so a second time, without testing it
as specified.
Having recognised this issue I feel that this may well be a significant factor in the apparent
'failure' of batteries to pass the annual 'full duration' or even some of the 'periodic functional'
tests.
A battery that is not discharged/recharged on a regular basis has a very short shelf-life'. If you
have a battery in your stores or van that has been lying there for 6 months or more – throw it
out!!
On a similar basis, be careful of the state of batteries you purchase
