RMDC Series Installation Instructions 52-376 Rev B01
ABC See “Accessory Board Connector.”
Accessory Board Connector Connector on some AlarmSaf power supplies and accessory boards, allowing plug-in expansion
of the system.
Accessory Board AlarmSaf product used with AlarmSaf power supplies having an ABC connector. These boards
allow plug-in expansion of system functionality.
AC-DC Converter DC power supply whose voltage input is either direct from the AC line or though a step-down
AC transformer.
Buss 1 (B1) Primary DC voltage in a system. Typically the higher voltage in dual voltage systems.
Buss 2 (B2) Secondary DC voltage in a dual voltage system.
Class 2 Power Limited See “Power Limited”.
Controlled Distribution Voltage distribution providing on/off control for the outputs. Control can be from FAI, an
access control panel, card reader, or other device.
DC-DC Converter DC power supply whose voltage input comes from another DC source. DC-DC converters allow
multi-voltage system backup with a single battery set.
FAI See “Fire Alarm Interface.”
Fire Alarm Interface Input on some AlarmSaf products allowing control of system output(s). Typically used for
dropping power to maglocks on egress doors during a fire alarm condition, can also control
other functions, such as resetting smoke detectors.
Negative Trip Input activated by the switching of a DC Common to its terminals. The DC Common can be
from an external (common grounded) source, or can be provided as one of the input terminals,
depending on the product. This input type is used with a dry contact or open collector input.
Positive Trip Input activated by the switching of a positive DC voltage to its terminals. The positive voltage
can be from an external (common grounded) source, or can be provided as one of the input
terminals, depending on the product. This input type is used with a dry contact or voltage input.
Power Limited Voltage output or wiring which conforms to NEC Article 725.
PTC Resettable overcurrent protection device.
Rack Mount Product that fits in a standard 19-inch equipment rack.
Simple Distribution Voltage distribution without control functions for the distributed outputs. Power is always
available to the outputs.
Voltage Distribution Splitting a bulk power supply output into multiple, current limited outputs to prevent a single
circuit failure from talking down an entire system. Multiple terminal outputs simplify wiring by
providing a pair of terminals for each circuit, rather than wiring several circuits to a single pair
of terminals.
