Inputs
The IRC-2000 has eight fully supervised inputs, two sets of four each with two common
terminals, and the URC-2000 has four fully supervised inputs, two sets of two each with
a common terminal. All inputs are individually programmable from the PC. The panels
employ digital filtering to eliminate the effect of interference on the input loops and to
verify all loop changes before reporting to the controller.
Each input can report up to four states; Open, Short, Abnormal, and Normal. For
example, if the circuit type is programmed as „2 resistor normally closed‟, 1k represents
a normal state and 2k represents an abnormal state. Less than twenty ohms is a short and
very high resistance is an open.
RTE (Request to Exit)
Inputs programmed, as RTE will be connected to push buttons mounted on the door or to
motion detectors mounted near the door. Activating the RTE input will cause a grant
access to be executed on the appropriate door. The RTE can be disabled by a schedule.
Multiple inputs can be programmed as RTEs for the same door.
DC (Door Contact)
Inputs programmed as door contacts monitor the state of the door. Forced entry, door
held open alarm, and door held open warning require monitoring of the door state.
General Purpose
General Purpose Inputs are inputs that are not tied directly to an access point. The user
defines what happens when they change state. They can trigger links, cause alarms,
and/or report their change of state.
