Emergency Lights

12/15/2009 2:22 PM

Hello,

I have these emergency lights at this store which are powered by a 277/480 system, I see the red ac light on all the sales floor bug eyes, however when I shut the circuit off, none of those lights come on, just one in the back side of the store and one in the office as well. There are around 10 bug eyes in the sales area and none of those come on, I'm a little confused since 10 bug eyes is a large number and I'm assuming it could be something else rather than just the batteries or the bulbs. I thought also that because not many apprentices are used to wiring 277 they might just have connected them to the 120 line and ended up burning something or causing the battery to malfunction. Any ideas on what could it be? I also checked the light bulbs and they seem intact! I did press the test buttom in all of them and again, nothing.

Thanks!

If the batteries are over 5 years old in the emergency lighting, they are likely to be dead. You can usually buy replacement batteries much cheaper than replacing the unit (including labor) but if the red "power on" pilot light is illuminated, then the device is wired correctly.

I suppose that by "bug eyes" you are referring to the disk or headlight shaped lamps. Even if there is a "test" button, the lamp will appear to be dead as long as the battery is dead.

Look on the internet for the mfg. literature on those units. It should verify what I am saying.

Its like the emergency lights have a common source,so why will one in the back side of the store and one in the office come on and the others do not come on?

U need to carry out good trouble shooting to find out if its wrong wiring,connection,supply or if the bulbs are bad or if the batteries are weak or dead.Since 2nos are still working under test,trouble shoot yr cct and find the fault and correct it.U may test the bulbs not working with the fittings of the ones that are working.Use yr multimeter to test voltage at each point whether u get the value expected at that point.These are trouble shooting steps to solve yr problems.

I would tend to agree with post #1. How long do the lights that work remain lit before dying out?My guess is less than 15 minutes or so. Look up the manufacturers specs for replacement batteries. It takes only a few minutes to replace the battery,just pull off the spade lugs and reinstall IN THE CORRECT ORDER on the new battery.
