Diesel Fire Pump Controllers


8/52

Operation Diesel controllers monitor the fire sprinkler

system pressure by means of a pressuretransducer or pressure switch.

Upon detecting a drop in system pressure, astart signal is sent to the engine, initiating itscrank cycle.


9/52

Starting The starting process can be initiated by causes

other than a pressure drop, such as a signal froma Deluge Valve opening or a Remote Startpushbutton being activated.


10/52

Number & Capacity of Batteries NFPA 20, Section 11.2.5.2.1

Each engine shall be provided with two storagebattery units.

At 4.5 degrees C (45 deg. F) - each battery unit shall

have twice the capacity sufficient to maintain thecranking speed recommended by the enginemanufacturer.


11/52

Crank Cycle NFPA 20, Section 11.2.5.2.1

The attempt to start cycle shall be of a 3 minuteduration - consisting of 15 seconds of crankingfollowed by 15 seconds of rest, in six consecutive

cycles.


12/52

Stopping There are 2 approved methods of stopping a diesel

controller. Manual Electric Shutdown Manual shutdown shall be accomplished by either of the

following: Operation of the main switch inside the controller. Operation of a stop button on the outside of the controller enclosure.

(The stop button shall cause the engine to shutdown through theautomatic circuits only if all starting causes have been returned

to normal - ie: pressure rises above the start point.) The controller then returns to the full automatic position.


13/52

Stopping Automatic Shutdown after Automatic Start.

There are several conditions that must be met for thismethod to be used.

All starting causes must have returned to normal for a

minimum of 30 minutes.


14/52

Stopping Automatic Shutdown after Automatic Start.

The engine cannot shut down automatically on highwater temp. or low oil pressure when any startingcause exists.

If no other starting cause exists during engine test,shutdown is permitted.


15/52

Battery Chargers NFPA 20, Section 8-2.5.2.4

There are several stringent requirements that BatteryChargers must meet under this section of the NFPACode.

This is an extensive section of the code - withoutproperly charged batteries, there is no way to start theengine - hence . NO FIRE PROTECTION


16/52

Battery Chargers NFPA 20, Section 11.2.5.2.4

Chargers shall be specifically listed for fire pumpservice.

The rectifier shall be a semiconductor type.


17/52

Battery Chargers NFPA 20, Section 11.2.5.2.4

When the battery (lead-acid type) reaches a fullycharged condition, the charger must reduce thecharging rate to less than 500mA.

The charger must charge the battery withoutdamaging it - and must restore the battery to 100% ofreserve capacity within 24 hours.


18/52

Overpressure Requirements NFPA 20, Section 12.4.1.3

Due to the introduction of pressure limiting drivers there is a requirement for the controller to monitoroverpressure.

For engines equipped with pressure limiting controls,the controllers are required to provide visual andaudible indication when system overpressure

reaches 115 % of total rated head pressure.


19/52

Electronic Engine Requirements NFPA 20, Section 12.4.1.3

Due to the introduction of electronic engines into themarket, a visible indicator and audible alarm must beprovided for the conditions ECM Selector Switch in

Alternate and Fuel Injection Malfunction. In order to meet the requirements, two pilot lights

and relay contacts are added to the controller.


20/52

Electronic Engine Requirements NFPA 20, Section 12.4.1.3

Controller terminal strips have two additional terminalsfor connecting to the engine control panel.

They are as follows: Terminal Number: 301 - ECM Selector Switch in Alternate Terminal Number: 302 - Fuel Injection Malfunction


21/52

Microprocessor -vs- Relays Microprocessor based controllers provide several

advantages over relay-based controllers .. Advanced diagnostics and troubleshooting Communication Memory for storage of alarm conditions On site changes performed easily Digital accuracy of parameters

Jockey Pump Controllers


40/52

Purpose Plumbing systems can encounter leaks for

various reasons. Leaks = drop in pressure - (usually minor - only a

few psi) The pressure must be kept at a level that will

enable the system to react correctly in case of acall to start.


41/52

Purpose Since the pressure drop is minor - the fire pump

should not be called upon to keep the pressureat a minimum level.

A smaller Jockey Pump is used to keep thesystem pressure at the desired constant.

A separate Jockey Pump Controller is used tocontrol the jockey pump.


42/52

43/52

Operation The Jockey Pump controller is essentially an

Across-The-Line combination starter with apressure switch.

The pressure switch is set to operate at aspecific set-point - set on site.


44/52

Operation Typically the jockey pump starting set point is

10psi above the set point of the fire pumpcontroller.

This allows the jockey pump to cycle on and off,as needed, to keep the pressure at the desiredpsi - without excessively cycling the fire pump.


45/52

Breakers -vs- Fuses Typically two styles of jockey pump controllers

can be found in the market. For turning power on and off to the controller -

either a fusible disconnect or a breaker with amechanical operating handle are utilized.


46/52

Breakers -vs- Fuses One of the most common reasons breakers are

used over fuses, are on-site disappearances offuses.

However, breaker style controllers may be moreexpensive depending on which manufacturerchosen.


47/52

Circuit Transformers The control voltage in the jockey pump controller

is typically line voltage or 120V, 3 phase. The controllers can have a transformer in the

circuit which operates on full line voltage andsteps down the voltage to 120V.


48/52

Overload Protection Thermal overload protection is allowed by code. Overloads are sized according to the namplate

Full Load Amps (FLA) on the motor. Most jockey pump manufacturers size the

controller for the appropriate Hp and supply theproper size overload.


49/52

Options Enclosure Type - NEMA 12/3R/4/4X Single Phase Service (120V or 220V) Low Suction Shutdown c/w Pressure Switch Space Heater / Thermostat / Humidistat Power On Light Extra Contacts


50/52

Run Period Timers (RPTs) A Run Period Timer can be added - as an option

- to a standard jockey pump controller. The purpose is to ensure that the jockey pump

runs for a minimum period of time, when there isa call to start due to low pressure.
