5.0 Inputs and Outputs
System Inputs
e system has the capability of monitoring up to 4 door status inputs, 4 request to exit (REX)
inputs, 4 auxiliary general purpose inputs and 2 digital inputs (reserved for future release).
All inputs are assigned default features that can be congured as needed. e following table
shows the default states for each of the inputs:
Table 5.1: Default Input States
Input Default State
Door Status Inputs Normally Open, Unsupervised, 8 Second Held Open Time
REX Inputs Normally Open, Momentary, Unsupervised
Auxiliary Inputs Normally Open, Unsupervised
Door Status Input
e door status input monitors whether the door is in an open or closed state. A door status
switch (typically a magnetic reed switch) will change states when the door is opened or closed.
e door status input does not require any programming to enable. Simply connect a magnetic
reed switch to the appropriate door input as shown in the control panel illustration, Figure 2.1.
Request To Exit
e Request to Exit (REX) input is a momentary input closure that activates the door output relay for
the same amount of time as a valid card swipe or keypad entry. REX devices can include a press-to-
exit switch on the inside of a door or a passive infared detector (motion detector), which allows con-
venient egress. e REX input does not require any programming. Simply connect a normally open,
momentary input device to the REX inputs as shown in the control panel illustration, Figure 2.1.
Auxiliary Inputs
e auxiliary inputs are general purpose inputs that can be used with a variety of input devices
including CO2 detectors, alarm system integration, etc. ese inputs can be congured via pro-
gramming to trigger a dened action such as to activate an output.
