You can power the Single Door Controller (SDC) using PoE+, PoE, or an external 12V-24V supply. Avigilon Alta recommends using PoE+/PoE for a few reasons:

• You simplify cabling by using one cable for both power and data

• You can use the POWER IN on the SDC for a backup battery

SDC power specifications

Operating Voltage: 12-24VDC

Input Rating: 12V @ 2A (min) or 24V @ 1A (min)

Output Ratings:

• Power Out connector can supply up to 100mA @ 12V or 50mA @ 24V

• 2 reader ports, max power output: 250mA @ 12V each

• 2 relays, max power output:

  • PoE: Max 3W combined output (e.g. 250mA @ 12V or 125mA @ 24V)

  • PoE+: Max 9W combined output (e.g. 750mA @ 12V or 375mA @ 24V)

Using a backup battery:

Assuming an external 24V power supply, an SDC configured with two Avigilon Readers and locking hardware uses about 1.1 Amps. To keep the system running for 3 hours with all entries engaged, you need 1.1A x 3 hours = 3.3 AH, so two 12V 4AH sealed lead acid (SLA) or gel cell batteries in series.
