665.3 Appendix 3 – Battery Standby Calculation ChartUse the following charts and associated notes to calculate the size of the batteries required to ensure operationof the installation in the event of AC Mains power failure. This chart is applicable to all panels except: 5100N,5200N and 5400N17.Quiescent Load Fire Alarm LoadEquipment I (A) x Total I (A) x TotalChassis 0.072 1.0 = 0.072 0.125 1.0 = 0.125Loop Driver Loop 1 0.042 1.0 = 0.042 1.0 =Sensor / Loop Current18 1.2519 = 1.25 =Loop Driver Loop 220 0.042 1.0 = 0.042 1.0 =Sensor / Loop Current 1.25 = 1.25 =Loop Driver Loop 320 21 0.042 1.0 = 0.042 1.0 =Sensor / Loop Current 1.25 = 1.25 =Loop Driver Loop 420 21 0.042 1.0 = 0.042 1.0 =Sensor / Loop Current 1.25 = 1.25 =Mxp-503 AdNeT Network Card 0.020 1.0 = 0.020 1.0 =Mxp-509 AdNeT PLUS Network Card 0.043 1.0 = 0.043 1.0 =Mxp-513 LED Indicator 0.008 = 0.03022 =Mxp-507 2-Way Relay Card 0.000 1.0 0.000 0.03022 1.0 =Mxp-532 Routing Interface 0.031 1.0 = 0.04322 1.0 =Mxp-504 VdS Interface 0.025 1.0 = 0.03422 23 1.0 =Mxp-504 VdS Interface Supply Outputs 1.0 = 1.0 =Auxiliary Supply Output24 1.0 = 1.0 =Sounder Output A 1.0 =Sounder Output B 1.0 =Sounder Output C20 21 1.0 =Sounder Output D20 21 1.0 =Total Quiescent Load = Alarm Load =x 24 hr = Ahrx 48 hr = Ahrx 72 hr = Ahr x 225 x 0.5 hr = Ahr (carry forward) + AhrTotal Load (Quiescent + Alarm) = Ahrx 1.2525 (Battery De-rating factor) = Ahr17 See Nittan protocol addendum for the battery calculation when using the Nittan protocol since the loop voltage is different to other protocols.18 Use the detector manufacturers’ technical information to calculate the load on the loop for both the quiescent condition and fire alarm condition for all loopdevices. By default, a maximum of 5 detector / call point LED indicators will be turned on in a fire alarm condition. (This number can be changed via the PCProgramming Tool).19 The calculated loop loading must be multiplied by a factor of 1.25 to calculate the actual current draw from the batteries. This is to take into account voltageconversion and conversion efficiency in generating the supply for the loop.20 Not available on Mx-5100.21 Not available on Mx-5200.22 Worst Case – All LEDS are ON. All Relays / Outputs are ON.23 Does not include any supply loads for router, FAT, FBF, etc. Include these loads in the separate line.24 Refer to separate data sheets for the additional modules that can be powered from the panel AUX Output to determine the AUX loading currents. Forexample, the modules can include 4-Way Relay, 4-Way Sounder, Modem, Page, Sounder Splitter, etc. The sum of all these additional currents should beentered in these fields. Ensure that the total alarm load does not exceed the AUX output rating.25 The alarm load should be doubled to allow for changes in battery efficiency for loads in excess of the recommended C/20 discharge rate. The total loadcalculated should be multiplied by a de-rating factor of 1.25 to allow for changes in battery efficiency over time. The above calculation is in accordance with therecommendations in BS5839-1: 2002.www.acornfiresecurity.comwww.acornfiresecurity.com |
