2.2.3 Real-Time Clock Protection

The panel RTC is backed up using a super capacitor. The super capacitor will power the real-time clock for 24 hours in the absence of primary power or backup battery.

2.3 Power Supply

The NetAXS-123 Compact Enclosure is powered by Power Over Ethernet (PoE) injector. This PoE injector can supply a total system current of 800mA to 900mA @ 12VDC. However the NetAXS-123 controller board consumes 400mA of current, and it therefore leaves 450mA of total current for the 12VDC external power. See Hardware Specifications, page 60, for further details on current limits using PoE.

The Standard Enclosure uses a 12VDC 4A power supply with an international input of 100VAC to 240VAC. The supply also charges and monitors the condition of the battery. Wire the unswitched electrical power to the supply per the National Electrical Code as well as any local electrical codes, including the safety ground wire.

An input power indicator is supplied, and it is illuminated when input voltage is present. If the indicator is off, the input voltage is off, or too low to operate the system.

Caution: Disconnect the battery and AC power before servicing the fuse. For continued protection against the risk of electric shock and fire hazard, replace the input fuse with a GMA type fuse with the rating of 1A, 250V. The fuse is located in the lower-left corner in the cabinet, as shown below.
