3 1.0 Control Panel Overview Features Complies to AS 2941/2008 Phase Failure Protection 12V Battery Charger for monitor battery Controls for 240V Jacking Pump c/w Man/Off/Auto selector Lamp Test F.I.B relays Audible alarm with mute for pump run and common faults 1.2 Description The FPC Fire pump controller is designed to control a three (3) phase fire pump unit. It can be operated manually via a push button on the panel facia or via a remote pressure switch. The control panel complies with AS (Australian Standards 2941) and includes all switches and displays as required. The panel has phase failure protection and a battery charger for the Monitor battery which monitors system status complete with terminals for a remote alarm. User Interface Display Keypad Inputs Pressure Switch J/Pump Pressure Switch Outputs Remote Alarm Power Supply LED Signal Lights and Analog Current and Voltage meters. Nil When the pressure drops in the system, the pump will start and can only be manually stopped. Operates on and off automatically as set by the pressure switch. Connection available for additional remote alarm 415V three (3) phase Active, neutral & earth power supply. 12VDC supply from the battery is used to supply power to the monitoring control circuit. Mechanical Specification Enclosure Pump Unit Mild steel powder coated Signal Red IP54. See Pumping detail by Pump supplier. FPC Page 3

4 Environmental Specification Operating Temp Relative Humidity Vibration -10 to 50deg C Do not install in areas of high humidity. Locate control panel internally where possible to help reduce heat & weather damage & increase mechanical life. Do not install in a location that is subject to large amounts of vibration. 4 FPC Page 4

5 2.0 Installation 5 Note: If any damage to control panel if found, please notify Inca Control Pty Ltd as soon as possible prior to installation. The control panel can be wall mounted separately from the pumping unit; distance is governed by the cable sizing. It is recommended that the control panel is within view of the pumping unit for safety reasons. If not in view, lockable ON isolating switches must be installed at the pump motors. 2.1 Mechanical Installation Mount the control panel via the mounting holes in each corner at the back of the enclosure using minimum 6mm screws, nuts & locking washers, or masonry anchors. Install in a dry well ventilated location that matches with environmental specification in 1.2 above. The panel shall be securely mounted in a vibration free location that does not subject operating personnel to unreasonable hazard from hot surfaces or moving parts of the pump or power transmission equipment. 2.2 Electrical Installation Note: All cable entries must enter via the bottom of the cabinet. If cables are entered via the roof Inca Control Pty Ltd reserve the right to withdraw warranty because of the possibility of shaving entering sensitive electronic equipment. 2.3 Maintenance Check that all connections are tight as copper is soft & can work loose. Check that all controls are functioning as intended. FPC Page 5

6 3.0 Description Battery Charger The panel is equipped with an automatic battery charger that provides 4A continuous boost charge when battery voltage is low and trickle charge when maintaining battery float voltage. The Battery Charger has an automatic in built current limiting facility and is capable of fully recharging the battery from 50% capacity within a period of 24 hours. The charger services the battery for the monitoring control circuit. Note: If batteries Are dead flat (below 3 volts), the charger will not charge and the battery will require a boost from a separate battery to bring voltage up to sensing level above 3V. 3.2 Panel Facia The front of the control panel houses the LED indicating lights, switches, ammeters, voltmeters and push buttons that control the panel function. Indication AC Supply On/Off Fire Pump Run Alarm silenced Battery Charger Power Fail -indicates mains power status -indicates when the pump is running. -indicates when the alarm has been muted -indicates that the battery charger supply has failed 3.3 Battery current charging and Voltage Meters On the panel facia display is an ammeter indicating the battery charge current for the battery. A separate voltmeter indicates the battery voltage. 3.4 Ammeter Selector Switch An ammeter selector switch is located on the panel facia and is used to monitor the current in the respective phases (red, white and blue). By selecting a phase at the ammeter with the switch, the motor current is indicated. 3.5 Phase Failure Relay The Phase Failure Relay is designed to provide protection for motors or pumps from the damaging effects of excessive negative sequence voltage resulting from phase failure, phase unbalance and reversed phase sequence. When connecting the 415V supply to the panel, the correct phase sequence will be indicated by a visual alarm on the relay. If the alarm is indicative, then any two (2) phases at the supply should be swapped or changed. FPC Page 6

7 If the phase sequence is correct at the relay and the pump motor is operating in reverse, change phases at the contactors and NOT at the supply end (isolator) as shown in section 4.3 (Panel Connections) Audible alarm The panel has an audible alarm that sounds when a fault condition has been registered and is silenced when the mute button on the panel facia is pressed. Alarm conditions are: AC Supply fail Fire pump running Battery charger fail FPC Page 7

9 5 Operation System Operation The FPC Fire pump controller is designed to control a 415VAC fire pump unit either operated manually via a push button on the panel facia or automatically via a remote pressure switch. The control panel when called upon will start the pump and sound an aural alarm while running and suppling water to fire services within a building or property. When the system requires to be stopped, the ONLY method is to press the stop pushbutton located on the panel facia. The monitoring battery maintains its charge by the use of a 12VDC 4A battery charger and complies with AS (Australian Standards 2941). Throughout the duration of the system monitoring, a range of fault conditions when called for, sound an aural alarm as specified in section 3.5 of this manual. 6.2 Jacking Pump (Automatic and Manual) Jacking pumps are used to boost the installation pressure in automatic fire systems to a pressure higher than the supply pressure to ensure that the system alarm valves do not operate as a result of supply pressure fluctuations. They may operate in automatic or manual mode. FPC Page 9
