1.What Is Emergency Lighting?

Emergency lighting is lighting for an emergency situation when the main power supply is cut and normal electrical illumination fails. The loss of mains electricity could be the result of a fire or a power cut. Without emergency lighting this could lead to sudden darkness and possible danger to occupants, either through physical danger or panic.

Emergency lighting is normally required to operate fully automatically and give illumination of a sufficiently high level to enable all occupants to evacuate the premises safely. Most new buildings have emergency lighting installed during construction;

2.What Is The Required Duration Time For The Emergency Light?

The time required to evacuate the premises depends on the size and complexity of the house. The duration itself is dependent not only on evacuation time but also on whether the premises are evacuated immediately the power and normal lighting fails and are re-occupied immediately the supply is restored. The minimum duration of an emergency escape lighting system is 1 hour. That means that once the power supply fails, the luminaires must remain on for at least one hour. One hour’s duration should only be used if the premises are evacuated immediately on supply failure and not reoccupied until full capacity has been restored to the batteries.

A minimum duration of 3 hours should be used for emergency escape lighting if the premises are not evacuated immediately, as in the case of sleeping accommodation, for example, or if the premises will be reoccupied immediately the supply is restored without waiting for the batteries to be recharged. Most buildings are required to have maximum 3 hours duration time.

3.How Often For Us To Check The Emergency Lighting?

You should carry out monthly tests and annual tests.

MONTHLY EMERGENCY LIGHTING TEST

·You must test all emergency lighting systems each month.

·Check that emergency lights and signs are clean and in working order.

·The test needs to be long enough to check that the lights are working properly.

·You must record your results and have any issues fixed ASAP.

ANNUAL EMERGENCY LIGHTING TEST

Once a year, you must drain your emergency lights fully—that is, leave them on for their full battery life (this might be one hour, three hours etc.). The lights should stay on for that entire time.

·Switch off the main electricity supply.

·Check all the lights. They must still be working at the end of the test.

·Record results and fix any issues ASAP.

·Switch the mains back on.

4. What Is The Difference Between NiCd, NiMH, And Lithium?

Customers are always confused about battery selection and setting up emergency light solution. A vast majority of emergency backup power kits that we sell come with standard functions and specifications are rechargeable batteries. These rechargeable batteries fall into three categories (NiCd, NiMH, Lithium), and we are often asked to explain the difference and how to choose a suitable battery for emergency lights.

Here are the major differences between the three categories:

Nickel Cadmium (NiCd) Batteries are currently one of the most reliable and high safety chemistries in the market. NiCd batteries give more watt-hours of operation per shift as compared to other battery chemistries. They are ideal for a user who needs high-performance battery with high safety and long lifetime and for usage under extreme conditions of cold and heat (-20C to +50C)

Nickel Metal Hydride (NiMH) Batteries offer shorter operation life with 500 cycles as compared to Nicd. These batteries provide 2 times more capacity than NiCd under same size, and operate as efficiently as Nicd in extreme temperatures. In addition, it is environmental friendly battery.

Lithium Ion (Li Ion) Batteries power to weight ratio exceeds that of NiMH for a lighter, smaller power supply. These batteries tend to be the industry’s most economical chemistry, and they offer good performance in extreme temperature.

In conclusion, the type of battery to be selected depends on the preferences of the customers. Upon research on LinkedIn group talk, we analyzed the basic selection criteria of customers, which is as follows:

Some customers: “Consider all possible technically adequate solutions, analyze discounted cash flow forecast over the expected lifetime of the installation and choose the financially optimum solution at the applicable time and assess maintenance and replacement cost.”

Others: “Prefer lithium battery for good performance of temperature and lower price.”

1.How To Buy A Suitable Emergency Battery Kit?

When it comes to batteries, even small variations affect longevity. The reason is batteries used for emergency lighting rely on delicate chemistry. When the chemistry is just a little off, the battery cells don’t pack the same amount of punch as was anticipated. To avoid this, it’s important to go with a trusted brand of battery, one that has a track record of consistent results.

About Maintenance

Correctly selecting and properly installing all necessary exit signs and emergency lighting is not the end. Testing and maintenance are also required. Egress pathways need to be kept clear. Any clutter which can hide or impede the proper operation of exit signs and emergency lighting need to be removed. Equipment may have become physically damaged, over time batteries lose the ability to hold charge, and bulbs and lamps grower dimmer and finally stop working. Following NFPA guidelines, mandated in most states, will keep your fire safety equipment functioning as it is intended.

NFPA 101®, Life Safety Code® 7.9.3 & 7.10.9 require that exit signs and emergency lighting systems be maintained according to the following:

• visual inspection of the equipment once every 30 days
• 30 second illumination test under battery-backup power performed once every 30 days
• 90 minute illumination test under battery-backup power performed once every year
• written records of visual inspections and tests to be kept for inspection by the authority having jurisdiction

Allowances are made for the types of testing capability that may be built into each unit:

• 7.9.3.1.1 refers to equipment that needs to be "Manually Tested" (i.e. by pushing and holding down the "Test Button" on the unit)
• 7.9.3.1.2 refers to equipment designated as "Self-Testing / Self-Diagnostic" (i.e. has built-in circuitry that can perform the 30 second monthly and 90 minute annual tests)
• 7.9.3.1.3 refers to equipment designated as "Computer-based Self-Testing / Self-Diagnostic" (these advanced integrated systems allow testing to be controlled by computer)

Maintenance Tips

• Look for exposed or loose wiring (frayed wiring is itself a fire hazard and loose wiring can be accidentally snagged and lead to further damage). Any loose or exposed wiring should be secured.
• Is the unit securely mounted to the wall or ceiling? If not, this could easily lead to further damage.
• Look for cracks or blemishes in the housing. These could be considered cosmetic, but outdoor units with cracks may need to be replaced because of water seepage issues.
  [ Consider purchasing and installing protective guards & shields to protect your exit signs, emergency lights, and exit light combos from physical damage. ]

• "Manual Testing" - find the "push-to-test" button which is usually a distinctive red button. Depressing this button will interrupt AC power and engage the back-up battery. Exit signs should stay illuminated, and emergency lightings should turn on. Hold the button down for 30 seconds, noting that the illumination also stays on for the full 30 seconds.For facilities with large number of units, consider investing in "Self-Testing / Self-Diagnostic" exit signs and emergency lights.
• "Self-Testing / Self-Diagnostic" - This equipment has a "push-to-test" button and a diagnostic LED which illuminates to convey test results. While the actual self-test process may vary based on manufacturer and model, the following example shows how this feature works in general. Find the "push-to-test" button and push the button twice to activate the 30 second test. Leave, do something else and come back. Examine the LED telltale. Steady Green indicates normal service, while red (steady, double-blink, or triple-blink) indicates a failure of some sort. Press the test switch button again (once) to reset. (In addition to the above manual test process, these units can be set up to automatically perform a 30 second battery self-test once every 30 days).
• "Computer-based Self-Testing /Self-Diagnostic" - All testing is triggered and tracked via computer.
  [ The Exit Light Company does not carry this type of equipment at this time. ]

• "Manual Testing" - Same as above, except a clamp of some sort is recommended to depress the button for the full 90 minute test.
• "Self-Testing / Self-Diagnostic" - Same as above, except depress the "push-to-test" button 4 times to activate 90 minute testing. (In addition to the above manual test process, these units can be set up to automatically perform a 90 minute self-test twice every year).
• "Computer-based Self-Testing /Self-Diagnostic" - Same as above.

After Testing

Now is the time to evaluate repairing or upgrading versus replacing. For units that are in need of repair, The Exit Light Company carries a full line of replacement batteries, bulbs & lamps, as well as energy-efficient LED retrofit kits to upgrade older style exit signs with incandescent bulbs. The Exit Light Company also carries extremely modern, energy-efficient, cost effective exit signs, combos, or emergency lights.

Best Practices Tip: When evaluating cost of ownership, don't forget to consider self-testing / self-diagnostic exit signs and emergency lights for reduced maintenance time, and power-free exit signs which require no wiring and use no AC for zero energy costs.
