Connecting a Power Supply!The power circuits of this Control panel complywith the EN54-4 standard.In order to comply with the Safety regulationsin force, the Mains must be equipped with a bipolarisolating device for protection againstover voltage and short-circuit to Earth (e.g. automaticisolating switch).This Control panel is powered from the Mains(230V/50 Hz) through a Switching power supply, locatedinside the case. The J408 Control panel provideshousing for two 12 V, 7 Ah maximum batteries, whereas,the J424 Control panel provides housing for two12 V, 17 Ah maximum batteries for power during Mainsfailure. The non-volatile memory will hold the programmeddata at all times.In the event of Mains failure, the: GREEN Mains LED will turn OFF RED Mains LED will turn ONThe Control panel will monitor the batteries at all times,(refer to Static Test and Dynamic Test).Static Test The Static Test monitors the battery chargeduring Mains failure. In the event of Low battery status(below 22.8 V), the Battery LED will turn ON. If thisoccurs, the Mains power must be restored before thebatteries empty, otherwise, the system will shutdown.Low battery restoral (over 24.6 V) will be signalled byblinking on the Battery LED (Memory).Dynamic Test The Dynamic Test monitors the operatingcapacity of the batteries. In the event of a FailedTest result (batteries do not meet the Test requirements),The Battery LED will turn ON.If this occurs, the backup battery must be replaced immediately,otherwise, the system will be unable to functionin the event of Mains failure (black-out).Battery trouble restoral will be signalled by blinking onthe Battery LED (Memory). Connecting the Mains SupplyWork carefully through the following steps (refer to thefigures on pages 12, 14, 18 and 19).1. Locate the backup batteries in the housing 20.2. Using the Jumper (supplied), connect the batteriesin series.3. Observing the battery polarity, connect the batteryterminals to the wires 60.If you are connecting 17 Ah batteries, you must replacethe wire 60 and jumper connectors.J424: Use 17 Ah @ 12 V YUASA NP 17-12 FR batteries;J408: Use 7Ah @ 12 V YUASA NP7-12 FR batteries;or similar with case flame class UL94-V2 (orhigher).4. Connect the Earth wire to the [Q] terminal on theterminal board 53.5. Connect the Neutral wire to terminal [N], and theLine wire to terminal [L] on the terminal board 53.The Control panel will reset on power up.230 V50 HzLineNeutralEarthBLACK wireRED wireJumper+ –+ –AutomaticIsolatingSwitch12 V battery12 V batteryMain boardPower supplyNLFigure 20 Wiring diagram for the power supply34 Conventional Fire Panels J424/J408
