NFPA 111

The performance requirements for stored electrical energy systems, which buildings and other facilities employ as a backup supply of electricity in case the primary source fails, are covered by this standard.

Systems must have power sources, transfer equipment, controllers, supervisory equipment, and supplementary equipment to supply electricity to the selected circuits.

Benefits of NFPA 111

In the situation where an uninterruptible power supply (UPS) is required in case the regular utility supply is disrupted, NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems, is essential.

It is utilized in sectors like finance, information technology, and several medical specialties anywhere that a power outage, even for a short period of time, is intolerable or where continuous emergency power is mandated by law.

• Sources of power
• Transfer apparatus controls
• Equipment for supervisors
• Accessories are required to power specific circuits with electricity.

FAQs

Q1: What is slot power?

A1. The term “slot” in this presentation refers to the slot machines found in casinos. Since slot machines have nothing to do with life safety, it is highly common for casino owners and engineers to put the slots on emergency (NEC Article 700) power rather than Optional Standby Systems power (NEC 702). This is against the law.

Q2. Is it possible to build an emergency oil tank in a flood zone?

A2. As an illustration, ASCE 24 compliance is required by International Building Code 2701.1.8. As a general rule, the NFPA mandates flood protection. There might also be a problem with this for the Environmental Protection Agency.

Keep in mind that the sites of gasoline fills should be planned to accommodate 100-year floods. It is against the law to locate Level 1 or Level 2 emergency power supply system equipment to reduce the risk of flooding, according to the 2018 edition of NFPA 99: Health Care Facilities Code 6.7.1.2.6.

Q3. Could you please go over the specifications for refuge areas?

A3. People who are unable to utilize the stairs have the potential to become trapped in a building if there are floors above the level of exit discharge. A communication system is included in places designated for rescue assistance or sanctuary to enable individuals to alert the fire service to their whereabouts. Refuge areas are covered under IBC 1009.6.

Q4. What about using natural gas, fuel oil, and dual fuel to power generators?

A4. As a natural gas backup, certain engine generator sets can run on propane that is stored on-site. I’ve seen these generators in action, and the energy density of the backup supply ought to have been taken into account by the designer.

Since every fuel source has a unique energy density, the number of kilowatts that are accessible will differ depending on the fuel source.

Q5. What happens to smoke control systems if mineral-insulated cable is used? Is a raceway the only place it can be?

A5. When installed in accordance with the manufacturer’s instructions, MI cable is usually labeled by the manufacturer with fire duration ratings and does not need to be put in a raceway.
