You are bidding on a new unused 24 volt power supply manufactured by Sargent ASSA ABLOY. I opened the box to verify the condition of the cabinet of the power supply to ensure that there was no damage to the unit. Below is the information on the item provided by the manufacture: DESCRIPTION SARGENT Model 3521 is a 12 volt, 1 amp power supply delivered in a single lockable enclosure with the line voltage connection to be made by screw terminals. Model 3520 is the same unit with 24 volt, 1 amp output. Both units feature regulated, adjustable power with integral sealed lead acid/gel cell battery charging capability. Both units also meet Class 2 electrical requirements, which means under the National Electrical Code that output wiring need not be in conduit. Always check with your local building department to make sure you are complying with applicable wiring codes before installing these units. Note: Power supply is shipped without batteries. DC OUTPUT AND VOLTAGE ADJUSTMENT The DC capacity of the supplies depends on the exact voltage that is set and on whether or not batteries are employed. The supplies can output 1 Amp when set at precisely 12 or 24 VDC. However, we recommend that supplies not be operated at maximum capacity. This reduces the possibility of heat induced failure and also allows for later expansion of the installation. In addition, when the supply is powered by batteries, available current capacity is reduced because some current is used to charge the batteries. Therefore voltage must be set higher to 13.5 or 27 volts. 900 mA should be considered the maximum output of a supply when it is used with batteries. BATTERY CHARGING CAPABILITY The power supply incorporates a battery charging circuit appropriate for standby rated sealed lead acid or gel cell batteries. Battery backup is available by ordering a 737-12 Volt or 738-24 Volt Battery Backup Kit. Note: Dry cell or NICAD batteries must not be used. When batteries of the appropriate voltage are connected to the red and black battery leads following correct polarity, the batteries will be charged by the power supply. In the event of a line voltage power failure, the load will automatically transfer to the batteries. If the normally closed emergency contact opens at the terminals (Fig. 1), battery power will be cut off. EMERGENCY RELEASE Factory setting is 12 volts for 12 volt unit and 24 volts for the 24 V unit. Emergency release of DC output at the power supply is accomplished by using the unconnected “F” terminal. Connect the contacts of the release switch between “DC+” and “F” and then connect the load to “DC-” and “F”. When the emergency release contacts open, all DC power will be cut off. When used with a UL listed fire alarm system, use auxiliary latching normally closed contacts. Note: Do not use “trouble” contacts (Fig. 2). * A trouble contact is a contact closure that comes from the fire panel. A trouble contact is energized when a fire panel experiences an integrity issue either internal to the panel or wiring to the panel.
