Hi All, Thankyou in advance for your help
I have a block of 5 stories with a staircase timer already installed in a 3 wire connection setup.
I am trying to setup a UPS to supply the lights in the common areas so that it acts as an Emergency Lighting setup - when power fails the lights still go on-
the trouble is as follows
AEG staircase timer. works fine on Mains., If I simulate power failure by shutting off mains while the timer is going the lights keep on till the timer shuts off. however a soon as the lights go off for some reason the timer won't work anymore.
UPS output is standard 230V 50Hz
I tried replacing the timer with another brand (probably chinese make)
but irrelevant of UPS or Mains Power it keeps going on, wont turn off.
any ideas on why the AEG timer won't work on UPS are much appreciated.
Thankyou

- TL;DR
- AEG staircase timer works only on Mains not on UPS Power
