Emergency Light using 9 or 11watt energy saver lamp

I would like to get a circuit diagram which i can use to creat an emergency light so when power goes off then light comes on. It obviously must have abattery and must be rechargable as well
Thanks
Wayne

    Use 1 and 2 as a switch to turn your light on. When AC is applied, it keeps the light turned off. If you use 12 volts, the relay is available from Radio Shack. you wan the coil to pull in at 120VAC and the contacts rated for at least 12 volts, iif not 24.

My dear can you tell me how much backup u want. you can build it up to 8hour back up with charging circuit & reverse battary buck boost voltage while running on battary. this may increase your backup time. and the circuit is very simple. if u really want to make it then reply, i will sent u a circuit.

Instaling a new pilot light assembly inBryant 234B boiler. The wires to the emergency shut off are not color coded in wiring diagram. Does it matter which wire (only 2 wires)goes where?


Hi Anonymous.
An emergency shut-off loop will almost always be set up so that the circuit is closed during normal operation, with a press of the emergency off button breaking, or opening the circuit. It's set up that way so that if a wire in the emergency circuit breaks, or gets disconnected, the system will shut down, rather than allow operation where the emergency off won't work.

Functionally speaking, if you only have two wires to the switch/button, then which way you connect them won't matter, since the switch will complete the circuit regardless of which way you flow the current. From a Code and consistency standpoint, one of the wires will be ground, and one of them will be hot. Most switches have leads indicating ground and hot on them, and you should be consistent with that. If nothing else, if someone else is later servicing or replacing the switch, also not knowing which wire is which, then they have less risk of mistaking a hot wire for a ground and getting zapped.

Depending on the setup, and whether it's AC or DC on the loop, you should be able to use either a voltmeter or an electricians hot-wire-detector to tell which lead is the hot lead.

Hope this helps, and good luck!

it's the grounds if they're both flashing fast it's definitely grounds take a test light and see if its got power goes through the test light grounded to the frame and if the light comes on then it's definitely your grounds

if the bulbs are good then you may want to check for power at the bulb sockets. the circuit boards on the brake light housing goes bad and looks for ground on an adjacent circuit.

I have a 1595-SWTTRWCC4 switch. None of the wiring diagrams show the two black wires coming from the switch. I am using the switch to turn on a light above the sink and use the outlet for counter top...


If the wires are coming out of the switch portion & not the outlet, 1 goes to power the other goes to that color wire that goes to your light. All you are doing with a switch is cutting one side of your power, putting switch in completes the circuit when it is turned on. Or breaks the circuit when it is turned off. The other wires, power in & back to light get wire nutted together.

Im assembling a emergency ballast to serve as emergency light with the function also of a normal light it has a back up battery.i base the connection on the manufactures diagram.but i didnt work


You will need to check the circuit clearly and go on visually tracing the circuit/signal . If you are confirmed on your assembly to be free of errors then the possibility of the circuit containing errors is for sure.If you do not have experience in assembly and testing, then seek help from the nearest electronic service tecchnician to check for the frequency oscillation/ output driver in the circuit and solve. Hope you take my advice . Good day

No power to lighting ballast ,only lights up on loss of power 277v at emergency ballast


Follow the appropriate wiring exactly. There are about 6-8 different diagrams. Find your lamp type and number of lamps. Locate your ballast type (usually instant these days) Quite often these diagrams show a switch on the power lead going to the operating ballast. If it isn't on a switch be sure to wire it in with the lead to the emergency battery ballast.

Kill power to light and emergency single light does not turn on also with power on push test knob and emergency bulb not come on


Hello Ramon, Check the power back (battery cell) as without a functioning battery pack, the emerbency light won't function.

Typically the batery packs will need to be replaced periodically every 4-5 years, depending on the istallation location and ambient temperatures.

When you kill the power to the emergency lighting circuit the PSQ is switched to operate automatically on battery power only. The same thing occurs when you press the test button; it disconnects the lighting from the electric power that keeps the battery charged and ready for service. You might also want to check the bulbs with a test meter (remove the bulbs from the fixture and test with the Ohm setting) While rare that these bulbs burn out, since they aren't usually illuminated often, only during a power disruption/outage, etc.

Here's a link to the Lithonia site with the spec sheets for the PSQ series of emergency lighting products, for your use and reference.

No brake lights or dash lights


You obviously have a hard fault in the circuit. Somewhere in the system the power is grounding out before it is supposed to. I would download a diagram from autozone.com in the DIY section. There you can trace where the power is supposed to go and look for chaffed or bare wiring.
