PURPOSE:

• To cater the entire electrical load of the emergency lights, emergency exit lights and fire alarm panel in a balanced pattern with preset level of circuit protection.

 

• To provide uninterrupted power source to power outlets at all emergency lights and fire panel.

 

• To provide minimum level of lightings at all floors at times of total black out or during the changeover to the generator set.

 

• To maintain optimum level of lighting in offices area with reference to the external lighting level.

SCOPE:

• This SOP will be applicable for all uninterrupted power supply (UPS) backup and maintenance in the textile sector.

RESPONSIBILITY:

• Responsibility is imposed on the electrical engineer/Officer and the electrician who conducts the inspection, who have jointly inspected, then the Electrical Manager / HOD who will make sure that the inspection is done properly.

How to Do:

• Officer along with electrician shall visit at the location where ups are placed. Visually inspect equipment for loose connection, burned insulation or any other sign of wear.

 

• In amid of inspection, tightening loose terminal points, batteries terminals and connection to prevent any unintended loss/harm. 
  
  

• Uninterrupted power supply capacity rating is 1000Watt with attached dry batteries as liquid batteries are sensitive to orientation. Dry cell does not require keeping them upright.
  
  

•  Individuals must understand the requirement of NFPA 70E.At the time of UPS inspection occurs, technician should place the system into bypass mode or transfer the load to other source in order to check the emergency lights
  
  

• Authorized person check indication lights of on load and off load to work properly.
  
  

• Ensure UPS’s that are required are suitable for purpose and can be powered via three-pin plug.
  
  

• Clean and vacuum UPS equipment enclosure before conducting inspection.
  
  

• Technician visit UPS control DB to make sure smooth operation of breakers, magnetic contactor and relays. Then switch main source breaker to off position. Relay will automatically take UPS on backup mode.10Watt of emergency lights attached to that specific UPS must be functioning /operational. If not, check faulty light with the help of multi meter to measure voltage and current for possible rectification. Replace with the new light would be preferable.  
  
  

• Note down starting and ending time of UPS back time to make sure required standard time should be above ninety minutes.
  
  

• Ensure UPS’s are recorded on a file and regular inspection as per manufacturer instructions, are undertaken, with record kept.
  
  

• Notify Estate and facility of the intention to install a UPS of above 1KW prior to meet requirement.
  
  

• Instruction is to be given by officer to electrician wearing all PPE’s while corrective action plan to ensure problem does not occur again.

          The emergency power backup of batteries should not be less than 90 minutes.

1.   Illumination of Emergency lights

• Emergency lights of 10w install on above of every exit and emergency door.
• Place emergency light at the angle of 45 bearing angle in order to get maximum illumination.
• Emergency light Signs having lower Lux Level should be replaced.

2.   Emergency light Type

• The Emergency light type which is used in facility is LED Emergency light of 10w.

3.   Cleanliness

• Every Emergency light should be cleaned.
• Use stair to reach the light.
• Clean the emergency light using shiner and cloth. 
• Cleaning of the Emergency light is important, because it decreases the lux and overall fruitful efficiency of the lights.

4.   Coverage

• Emergency lighting system
• Emergency Exit
• Fire Alarm panel

Acceptance Criteria:

The points measured shall not be less than, the values standard values given in the table below.

 

Instrumentation	URS(User requirement Specification)
Emergency  Power Backup	According to user demand (90 Minutes approx.)
Illumination of Emergency light	According to user demand (900 Lumens approx.)
Emergency light Type	LED Emergency light (mostly 10watt)
Cleanliness	Dust Proof
Erection	According to facility Design for Emergency

Standards being followed:

Emergency light standards being followed in the facility.

• International Building Code (IBC), 2015 edition.
• NFPA 70: National Electrical Code (NEC), 2017 edition.
• NFPA 99: Health Care Facilities Code, 2015 edition.
• NFPA 101: Life Safety Code, 2015 edition.
• NFPA 110: Standard for Emergency and Standby Power Systems, 2016 edition.
• NFPA 111: Standard on Stored Electrical Energy Emergency and Standby Power Systems, 2016 edition.
• NFPA 70E
• NFPA 101 for emergency lighting

1.   Frequency of Emergency Lights Verification:

                    Frequency for UPS Verification is at least once in a month.

• To cater issues and concern in order to smooth functioning of UPS.
• International Building Code (IBC), 2015 edition.
  So that’s the reason why Emergency light Verification, inspection is performed after one month to fulfill the audit requirement.
