Page 3-14 Section 3 – Installation and Operation CFP83 Series Signal and Control Installation NOTE : Install signal and control wiring at Terminal Board TB. Refer to Drawing 10423 Sheet 1 in Section 13. Ensure that the fire control system is properly installed and configured as per the manufacturer’s instructions. Complete the customer-supplied fire pump controller wiring as per the manufacturer’s instructions. NOTE : Do not connect more than two wires at any point on the fire pump engine control panel terminal board. If necessary, add a grounding terminal board at the fire control system. Connect the control power from the fire pump controller at TB-1 (+) and TB-11 (-).
This power source is necessary for fire pump operations while in the AUTO mode. Connect the two redundant crank signals from the fire pump controller to TB-9 (Crank Battery A) and to TB-10 (Crank Battery B). Connect the signal ground to TB-11. Connect the Crank Terminate input to the fire pump controller from TB-2 with signal ground at TB-11. This 12 or 24 VDC signal is present when the engine is running. This signal indicates that the engine has started and that the crank command from the fire pump controller should stop immediately. Connect the remote overspeed alarm input to the fire pump controller from TB-3. This 12 or 24 VDC signal is present when the overspeed switch has operated.
If this event occurs, the fire pump engine will stop. The local RESET button must be pressed in order to restart the engine. Connect the Low Oil Pressure alarm input to the fire pump controller from TB-5. This 0 VDC grounded signal is present when the oil pressure has dropped below the 110 kPa [16 PSIG] setpoint. The engine will continue to operate but immediate attention is necessary in order to prevent excessive damage to the engine or catastrophic engine failure. Connect the High Water Temperature alarm input to the fire pump controller from TB-5. This 0 VDC grounded signal is present when the engine is running and the coolant temperature has risen above the 93 o C [200 o F] setpoint.
The engine will continue to operate but immediate attention is necessary in order to prevent excessive damage to the engine or catastrophic engine failure. If used, provide permanently installed redundant battery charging systems with connections at TB 6 and TB-8 (+) and TB-11 (-). TB-6 (+) and TB-8 (+) and TB-11 (-) should also be used for remote battery voltage indications at the fire control system or elsewhere. Ensure electrical continuity and adequate insulation resistance for the installed wiring. Provide the initial charge on the redundant batteries as per the battery charger’s instructions.
Check that both voltmeters on the local control panel indicate the approximate battery voltage. Drawing No. 9777, Section 3, Rev. 02-07
