Testing Emergency lighting circuits

[adam.2209]

I have just started installing temporary emergency lights for a fire alarm company i work for i am an electrician qualified to the 18th edition i do not currently do testing and inspection looking at doing this in a few months. Just looking for some advice and information about the testing of emergency lighting circuits once it is installed as i do not normally install emergency lighting.

I have installed 5 emergency LED bulkheads which comes from a key switch, the feed comes from the DB which is connected into the rcbo of the circuit feeding the normal lights so when it trips the lights will come on.

Can some one explain to me which test would have go to be carried out to ensure no damage to the LEDs

I have tried to ask another electrician that's doing to testing but not interested in explaining it to me

You test it like any other circuit. You either insulation resistance test between line and neutral before the fittings are connected then earth or you just connect line and neutral together and just test to earth if the fittings are connected, it won't damage them.

Aside from that you want to see the charging LED is functional when power is on and when off the charging light goes out and the emergency light comes on. As you have to wait at least 24 hours for the batteries to be fully charged you cannot practically do the three hour test. There is usually a schedule of tests to fill in with each emergency light as well. The date needs to be put on the battery as to when it was commissioned. But having done the functional tests that is it. There are requirements for 1 lux to hit the floor they are illuminating at one meter wide. Usually, apart from a lux meter, calibrated, you would use the manufacturers information on the lumens delivered to assure you meet that requirement. Then of course you would ensure that they are installed correctly in the sense the design allow for changes of direction and levels etc. according to BS5266

As above basic tests and record results on back of hand.

Get a copy of 5266-1 or have the company provide you with it as you'd do the standard electrical tests but there may also be (dependant on system) specific tests required by 5266-1.
