To support Wi-Fi unlocking from the mobile app, the SDC's inbound TCP port 443 must
be available from within the LAN. Inbound port forwarding on the router, firewall, or
NAT device is not required.
POWER REQUIREMENTS
The Openpath SDC can be powered with PoE, PoE+, or an external 12-24V supply. Use
an external power supply for backup or if PoE is not available—24V required if locking
hardware requires 24V.
Operating Voltage:
12-24VDC
Input Rating:
12V @ 2A (min) or 24V @ 1A (min)
Output Ratings:
l
Power Out connector can supply up to 100mA @ 12V or 50mA @ 24V
l
2 reader ports, max power output: 250mA @ 12V each
l
2 relays, max power output:
o
PoE: Max 3W combined output (e.g. 250mA @ 12V or 125mA @ 24V)
o
PoE+: Max 9W combined output (e.g. 750mA @ 12V or 375mA @ 24V)
SELECTING A BACKUP BATTERY
While not required, Openpath recommends having a backup battery in case of power
outages. The size of battery depends on your setup and how long you want to power
the system.

Assuming an external 24V power supply, an SDC configured with two Openpath
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.
