1-5 The Fire Alarm Back-up UPS1481 SIZING

Each model of the Fire Alarm Back-up UPS1481 is designed to supply a maximum load which is given by its kVA (1000’s of volt-amperes) and KW rating. It is very important that the load is within the rating of the FIRE ALARM BACK-UP ups1481 to ensure that the connected loads will be properly supported.

Volt - amperes (VA) are the number of current in amps a device draws multiplied by the nominal voltage supplied to the device. The total kVA of all the loads to be connected to the Fire Alarm Back-up UPS1481 is simply the sum of the kVA requirements of each device.

Each electrical device to be powered by the Fire Alarm Back-up UPS1481 should have a specification sheet attached to it which specifies the amount of power it requires. In addition, this information should also be listed in the manual supplied with each piece of equipment. The device’s nameplate should list the electrical requirements of the device in some or all of the following units: nominal voltage, current, VA or kVA, and watts or KW. If VA or kVA is not given, then multiply the nominal input voltage by the current shown on the nameplate. Add up the kVA requirements of each device to be powered by the Fire Alarm Back-up UPS1481.
