FA-GB2/B Power Supply for GB2 System
The GB2 series power supply unit(s) shall be Alpha Communications® / Golmar FA-GB2/B, or approved equal. The FA-GB2/B shall provide enough power and controls for up to 32 of the GB2 series monitors and one (1) door entry panel. If more than one (1) door entry panel is used, contractor shall furnish and install the required DP-GB2A door panel expansion unit. For systems larger than 32 monitors, additional FA-GB2/B power supplies and the required RD-GB2/A repeater/router unit(s) shall be installed as needed.
Contractor shall observe all local and national electrical and building codes.
The GB2's system uses simple 2-conductor non-polarized wiring making it ideal for new installations as well as for retrofit applications. All audio, video and data functions are fully digital and using the RAP-2150 (or equivalent) cable you can run up to 300 meters from the entrance panel to the furthest monitor.
The Alpha Communications® / Golmar FA-GB2/B power supply is used exclusively with the GB2 series systems. The FA-GB2/B power supply is located between the entry panel's BUS and the monitor's BUS.
The capacity of the FA-GB2/B is currently up to 32 monitors and one (1) entry panel. If there is more than one (1) entry panel, then the DP-GB2A needs to be installed.
For systems larger than 32 monitors, you will need additional FA-GB2/B power supplies and the required RD-GB2/A repeater/router unit(s) as needed.
The FA-GB2/B has a relay built-in for the connection of the staircase light. This relay is controlled from the monitors.
