Unless the generator runs the whole facility you can usually find out what it runs by finding the emergency breaker panel(s) and reading the list that should be on the door..

If the generator is connected through a good automatic transfer switch there will be a time delay (usually 5-30 minutes) before it switches back to utility. The generator will run for another five to ten minutes to stabilize internal temperatures before it shuts down.

Most building codes and manufacturers recommend a minimum run time of a half hour weekly under load to ensure the system is ready and able to work. Depending on your location and building use the weekly test may be required.

With so many different alarm systems in use my best recommendation is to have your alarm company walk your staff through the process.

If the generator is used for life safety equipment there is a great deal of liability associated with the system. Generally building management must see that the system is maintained in working condition and have repairs performed by competent technicians in a timely manner. The following are the basic maintenance responsibilities additional info can be found in NFPA publications.
1.Check/test the generator weekly. Sign and date a checklist noting operation and fluid levels. Retain these records in a maintenance file for inspection.
2.Have the system serviced at least semi-annually by a competent service company.
3.Repair deficiencies found during the weekly and semi-annual inspections without delay.
4. Some systems require quarterly service to meet code.

Most emergency generators only run about 50 hours per year and do not ‘wear out’ the oil from use. A more serious threat is condensation within the engine between exercise cycles contaminating the oil. We agree with most manufactures who recommend annual oil and filter changes coupled with an oil analysis program. This will usually be sufficient to prevent premature wear and reduce repairs.

By code fire pumps cannot use mechanical seals. Rope packing compressed against the shaft by collars need some water for cooling. Generally light to heavy dripping is acceptable. Heavy leakage when idle or running? would require packing adjustment or replacement, perhaps internal repairs.

The fire pump provides suitable pressure for fire fighting. Usually the fire department will use their pumper to better control the water flow but will use your fire pump in the unlikely event of a breakdown of their equipment. It will provide water to the sprinklers until the fire department arrives. Most fires in sprinkled buildings are contained by three sprinklers or less and are out before the fire department arrives.

Fires in dumpsters caused by someone throwing a lit cigarette down the trash chute. Always make sure the melting link that closes the trash chute door above the dumpster is in good shape and not blocked. Keep at least on spare melting link somewhere other than the dumpster room and keep the fire sprinkler clear and ready. Coastal Service stocks these melting links.

Evacuate the building in case there is a fire. While there is the possibility it is a false alarm due to equipment failure it is best to start by protecting people. Most fire departments forbid shutting off an alarm until the fire department has confirmed there is no fire.

Codes require weekly testing of both electric and diesel fire pumps. Maintenance and test records should be retained for inspection due to the high liability associated with this equipment. Repairs should be performed by a licensed company without delay. The local fire department must be notified when the pump is out of service, when you anticipate its return to service, and when you actually return it to service.

The small jockey pump maintains pressure in the system above the start pressure of the main pump. Small leaks are handled by cycling the pump. Should a sprinkler head activate or a fire hose be used the system pressure drops to the point the large pump starts.

The local fire department must be notified when the pump is out of service, when you anticipate its return to service, and when you actually return it to service.

Redundancy and energy savings. A two pump system should be designed so either pump can handle the whole building so that when one fails and is out for repair your water pressure is unaffected. A three pump system is usually more efficient and can also operate the building with one (perhaps two) pumps out for repair.

There is no current code requirement that addresses maintenance freuquency however Coastal Service recommend semi-annual inspections in order to to be sure the building occupants have uninterrupted water. These inspections usually turn up problems before they become expensive.

This tank stores water under pressure to allow pumps to shut off during periods of low usage. Having a pump that runs 24/7 wastes energy and increases both wear and repairs. It is a lot like leaving your car running while you sleep.

Obviously you want experienced, qualified people to maintain your water system as your health depends on it. Most municipalities require a plumbing license to work on water systems. The company should maintain sufficient stock on hand. Coastal Service and Supply in Largo, Florida is your perfect choice.

A pressure Reducing Valve (PRV) takes a high pump pressure and regulates it to a usable building pressure regardless of the pumps flow between no flow and full rated flow.

Turn that pump off and close the valves to that pump. Then call Coastal Service for repair.

The transfer panel monitors utility voltage and controls the starting, transfer, retransfer, and stopping of the generator. It usually has a time clock built in to control weekly exercising.

Contract customers can call Coastal Service for free training on the building's maintenance procedures.

Most buildings have their maintenance personnel perform the weekly checklist with the manager checking occasionally to be sure it is being done properly.
