Signals from Fire Pump to FACP

[mshields]

Our boiler plate specifications call for the following trouble and supervisory signals to be sent to the FACP from the Fire Pump/Fire Pump Controller. I've been challenged to identify where in the code these signals are required. I've looked in NFPA 20 (fire pumps) as well as in 13 (spinkler systems) and admitedly took a cursory look in NFPA 72. I'm comming up empty. Are these signals from the fire pump to the FACP required or are they just good practice?


Excerpt from our spec:
Fire pump supervision contacts to be provided by the fire pump
control equipment. Provide individual monitoring points, modules and
wiring to the fire alarm system. Provide trouble alarms for the
following:

1) Fire pump disconnect open.
2) Fire pump not in automatic mode.
3) Fire pump derangement.
4) Fire pump on.
5) Fire pump power failure.

l. Emergency power system supervision contacts to be provided by
the emergency equipment. Provide individual monitoring points, modules
and wiring to the fire alarm system. Provide trouble alarms for the
following:

1) Generator not in automatic mode.
2) Emergency system derangement.
3) Emergency system carrying load.
4) Battery charger not functioning.
5) Emergency system ground fault.

Here are some from NFPA 20
10.4.6.2 Phase Reversal.

10.4.6.2.1 Phase reversal of the power source to which the line terminals of the motor contactor are connected shall be indicated by a visible indicator.

10.4.6.2.2 When power is supplied from multiple power sources, monitoring of each power source for phase reversal shall be permitted at any point electrically upstream of the line terminals of the contactor, provided all sources are monitored.

10.4.7* Fire Pump Alarm and Signal Devices Remote from Controller.

10.4.7.1 Where the pump room is not constantly attended, audible or visible signals powered by a source not exceeding 125 V shall be provided at a point of constant attendance.

10.4.7.2 These fire pump alarms and signals shall indicate the information in 10.4.7.2.1 through 10.4.7.2.4.

10.4.7.2.1 Pump or Motor Running. The signal shall actuate whenever the controller has operated into a motor-running condition. This signal circuit shall be energized by a separate reliable supervised power source or from the pump motor power, reduced to not more than 125 V.

10.4.7.2.2 Loss of Phase.

10.4.7.2.2.1 The fire pump alarm shall actuate whenever any phase at the line terminals of the motor contactor is lost.

10.4.7.2.2.2 All phases shall be monitored. Such monitoring shall detect loss of phase whether the motor is running or at rest.

10.4.7.2.2.3 When power is supplied from multiple power sources, monitoring of each power source for phase loss shall be permitted at any point electrically upstream of the line terminals of the contactor, provided all sources are monitored.

10.4.7.2.3 Phase Reversal. (See 10.4.6.2.) This fire pump alarm circuit shall be energized by a separate reliable supervised power source or from the pump motor power, reduced to not more than 125 V. The fire pump alarm shall actuate whenever the three-phase power at the line terminals of the motor contactor is reversed.

10.4.7.2.4 Controller Connected to Alternate Source. Where two sources of power are supplied to meet the requirements of 9.3.2, this signal shall indicate whenever the alternate source is the source supplying power to the controller. This signal circuit shall be energized by a separate, reliable, supervised power source, reduced to not more than 125 V.

Thanks Ron.

I did see these in NFPA 20 in my search prior to posting the question. But, correct me if I'm wrong, these are all things that need to be annunciated via a remote annunciator. What I'm looking for is what the requirement is at the FACP relevant to the fire pump.

For example, if the fire pump doesn't start when it's supposed to is a supervisory or trouble signal sent to the FACP (or more to the point, does the code require it). When the Fire Pump is running, is there a supervisory input to the FACP such that the Fire Department knows about it.

Any fire alarm system installed on a premises must act as one system. You cannot have anything fire alarm related that is not controlled by the FACP (with the exception of HVAC shutdown). I believe you'll find this code requirement in the UFC (Universal Fire Code/not Ultimate Fighting although Chuck Ludell kicks ass).
