Inputs
The UNC100 has four fully supervised inputs, two on side A and two on side B. All Four inputs are added
as defaulted application by default, and can be programmed as General purpose from the PC
Number
Default Application
1
Request to Exit
2
Door contact
3
Request to Exit
4
Door contact
Each input has four states: Restore, Alarm, Trouble, and Illegal. Trouble is reported if a short or break is
detected on a supervised circuit and illegal is reported if the measured loop resistance lies between valid
states. For example, if the circuit type is programmed as “2 resistor normally closed”, 1k represents a
restored state and 2k represents an alarm state. If the loop resistance changes by more than 15% but not
enough to enter the next state, an illegal state is reported.
Request to Exit (RTE)
The Request to Exit [RTE] input is connected to a push button mounted on the door or to a motion detector
mounted near the door. A normally open or normally closed button can be used and the circuit type can be
programmed from the PC. Activating the RTE input will unlock the door. The RTE can be disabled by
time zone. This input can be used as a general purpose input if RTE operation is not required. If not used,
leave the default RTE settings in the Axiom™ software configuration.
Door Contact (DC)
The Door Contact [DC] input monitors the state of the door. Forced entry, door held open alarm, and door
held open warning require monitoring of the door state. This input can be used as a general-purpose input
if the door contact is not required. If not used, leave the default DC settings in the Axiom™ software
configuration.
Input Circuit Types
The device controllers supports seven different input circuit types ranging from no resistor for low security
applications to two resistor normally closed circuits where the highest security is required.
