To find the Output Voltage using the graph: — indicate theProbe temperature on the TEMPERATURE (°C) axis; draw a line from the temperature value point up to the curve a);draw a line from the intersection point across to the VOLTAGE (V) axis; adjust the Output Voltage of the Switching PowerSupply to the resultant value. For example, if the Probe temperature is 22 °C, the Output Voltage of the SwitchingPower Supply must be set at 27.4 V.TEMPERATURE (°C) -10 -5 0 5 10 15 20 25 30 35 40 45 50VOLTAGE (V) 29.0 28.8 28.6 28.2 28.0 27.8 27.4 27.2 27.0 26.8 26.6 26.4 26.2Table 3 Switching Power Supply Output Voltage chart. To find the Output Voltage using the chart: — select the nearestvalue to the Probe temperature on the TEMPERATURE (°C) row; read the respective value on the VOLTAGE (V)row; adjust the Output Voltage of the Switching Power Supply to the indicated value. For example, if the Probe temperatureis 22 °C, the Output Voltage of the Switching Power Supply must be set at 27.4 V.36 Conventional Fire Panels J424/J408
