8. Turn the unit OFF until needed during a power outage to conserve battery life. Type 2: Sealed Lead Acid (SLA) Battery Backup Unit (BBU) This type is a BBU at the Optical Network Terminal (ONT). If your Fiber Optical Network Terminal (ONT) has a Power Supply Unit (PSU)/Battery Backup Unit (BBU) you will need to order a Sealed Lead Acid BBU.
The battery charger powers the inverter while float charging the battery. For the lead-acid battery, the float voltage in this example is set to 13.8 VDC. The load is running off the inverter, and if mains power is lost, the battery keeps supplying power and the load keeps working, until the battery dies.
There are a few different options when it comes to choosing a reliable power supply, as well as some calculations that are necessary to ensure that the fire alarm system is provided with sufficient backup power. ... the most common type of battery is a Valve-Regulated Lead-Acid battery and they are typically located within the fire alarm ...
As opposed to the VRLA alternative, lithium-ion batteries use a metal oxide for the cathode, and a carbon-based material for the anode. The electrolyte is a lithium salt dissolved in an organic solvent. (By contrast, a lead-acid battery uses lead dioxide for the cathode, a lead anode, and sulfuric acid as the electrolyte.)
