I assume:
Type would be maintained or non-maintained?
Mode, perhaps permanent or switched?
Facilities, no idea?
Duration would be 1-3 hours?

I think type is to do with the battery, either self contained or remote from the fitting, mode is non maintained/maintaned etc I have no idea on facilities something to do with how it's tested i think.

You need to get a copy of the IEE "Electrician's guide to emergency Lighting" (the one with the yellow cover)
Section 4.8 (page 46) gives all of the options to answer this.
I would print it all out here, but there is rather a lot of info! You'll have to read it for yourself.
The bit on facilities is hard to get a handle on, but Gravid is right, it is to do with test facilities.
The book is a handy guide if you are working on EL. Whilst not cheap, I would class it as an essential toolbox guide for EL.

Heres a post I made earlier.

7.10 Categories of operation of emergency lighting systems
/
Categories of operation are specified in BS EN 50172:2004/BS 5266-8:2004, 5.6.
/
In this standard, emergency lighting systems are classified according to the following parameters, as given for luminaires in BS EN 60598-2-22:1999, Annex B:
/
a) Type:
X self-contained;
Y central supply;
/
b) Mode of operation:
0 non-maintained;
1 maintained;
2 combined non-maintained;
3 combined maintained;
4 compound non-maintained;
5 compound maintained;
6 satellite;
/
c) Facilities:
A including test device;
B including remote rest mode;
C including inhibiting mode;
D high risk task area luminaire;
/
d) Duration of emergency mode (in minutes) for a self-contained system:
10 to indicate 10 min duration;
60.............1 h duration;
120............2 h duration;
180............3 h duration.
Previously, emergency lighting systems were categorized by the prefix “M” for maintained and “NM” for non-maintained systems, followed by an “/” and the number of hours duration claimed for the installation, e.g. for self-contained systems:
—
M/1 was a maintained 1 h duration system; this is now [X][1][****][60]
—
NM/3 was a non-maintained 3 h duration system; this is now [X][0][****][180]
/
NOTE **** in the third box stands for the facilities [see item c)], details of which are added, as applicable, at the time of installation.
