Introduction Electric fire pump controllers are designed to start an electric motor driven fire pump. It can either start the fire pump manually through the local start pushbutton or automatically through the sensing of a pressure drop in the sprinkler system. The fire pump can be stopped manually with the local stop pushbutton or automatically after the restauration of the pressure in the sprinkler system.
Installation The LFX electric fire pump controller is intended to be installed in accordance with the Loss Prevention Standard 1237 Requirements for control panels for electric motor driven pumps used in automatic sprinkler installations and the Local Electrical Codes. Location The controller shall be located as close as practical to the engine/motor it controls and shall be within sight of the engine/motor.
The number of conductors required varies depending on the model of starter: 3-wires plus ground sized at 125% of full load current for model LFA. 6-wires plus ground sized at 125% of 58% of the motor full load current for model LFY. Incoming Power Connections Incoming normal power is to be connected to terminals identified L1 - L2 and L3 located on the disconnecting means IS.
Quick Start-Up Guide The rating label is the most important label. It must be read carefully to ensure the compatibility between the controller and the installation. Verify that the controller is installed securely on the wall.
Make sure to drill holes for the motor and power connections and run the cables inside the panel, all in accordance with the specifications in order to minimize interference with other equipment. Connect the input power and the motor on their respective terminals. Secure with the appropriate torque as indicated on the torque label and verify all connections.
Main Features Inputs Buttons: This controller is equipped with 3 pushbuttons and an Isolation Switch on the outside of the door. -Emergency Start (PB1-Green): This button is used to open the sensing circuit and trigger the start of the pump. It is protected by a plastic cover and should be used only in case of a real fire.
Alarms Alarms (Remote Alarm Panel) The LFX control panel provides four alarm light. Those alarms are also four output signals on the relay board that can activate alarms on a remote panel. - Pump On Demand: Activates when a pressure switch’s contact on the sprinkler system is open by a drop of pressure or when the Emergency Start button is pushed.
