Emergency lighting confusion.

[cloverman]

When you unplug the battery you are basically putting the unit into normal power supply mode (230V) and it will operate from the S/L
Connect the battery up and if it is dead the unit will not work as it identifies a fault

I believe you said that it is in an NHS property ?
Are they on a monitoring system ? Or just a basic Emergency light setup
Not at that makes any different from my experience !

Just a basic self contained lighting set up with tons of failed EM fittings. Also have a 3 position timed key switch marked up as Emergency test relay..I have no key to operate this but removing power at the mcb to the relay does not initiate any EM lighting at all which again points to a lot of failed lights.

Any installation or manufacturing dates in the batteries?

I've gone to some units whereby the batteries hadn't been changed since they were installed in the early 90's then people wonder why they don't work !!!
To be honest Rattlehead85, I would be inclined to swop them all for LED fittings, less hassle and if you are replacing parts in each fitting anyhow it will work out cheaper.

Get yourself some key switch keys from your local supplier, if this is something that you are doing on a regular basis you need them really

I have an emergency fitting from 1994 and the battery still lasts like 4 hours and I test it regularly I have newer L.E.D fittings that have had 2 battery changes in 5 years so older is sometimes better.

When 220v is working, mine has the green light on and halogen light is bright. During outage nothing works. Battery is 2 years old.
