Is this boots? Ive been to some boots and they had panels with a few buttons for emergency lightsThere is a large retail chain in the UK doing this, one push button and a 3hr timer.
Forgive my ignorance Tim, but in what circumstance would you use a contactor for emergency lighting, as I've seen a few new installs recently where one is installed next to the control mcb and ctu for emergency lighting. I hadn't the opportunity to look behind the covers yet, but my understanding was it was switching the emergency lighting. One unit had only 4x NM em lights and when I tested through ctu the contactor pulled and em lights came "on."I'm a little confused why you think you need a contactor to switch an 80W load (20 x 4 watts ) that draws 0.34 amps
My comments were based on installations I've seen in England and Wales and I've never encountered the system you describe which others have now explained is common in Ireland and sometimes in other places too. So best to disregard what I said!Forgive my ignorance Tim, but in what circumstance would you use a contactor for emergency lighting, as I've seen a few new installs recently where one is installed next to the control mcb and ctu for emergency lighting.

Hi Risteard,As mentioned it's done through a CTU (central test unit) and contactors rather than key switches.
I.S. 3217 are the Emergency Lighting Rules which need to be complied with - it's not BS 5266. It's done a bit differently.
