iSTAR eX Connections
The following types of iSTAR eX connections are available, as shown in
Figure 4.11 on page 4-18:
Input connector – associates a security device with an input on iSTAR eX
or add-on module board
Output connector – associates an event or input with a relay on iSTAR eX
or add-on module board
Read head connectors – Direct connect Wiegand signaling read heads,
RM reader modules, and Wyreless PIMS.
Inputs
An input is a software object that associates a security device, such as an alarm
switch, with an input on iSTAR eX or on an input module board. An input
reports the state of the switch. All inputs can be in one of two states: active or
inactive.
A supervised input reports on the status of the wiring between the controller
and the switch. If the wiring is cut, the system reports an open circuit. If
someone tries to jumper across the wiring (prevent the device from
reporting), the system reports a shorted circuit.
Supervised inputs can report a total of five conditions to the controller:
Short
Open Loop
Line Fault (resistance is outside of expected ranges)
Inactive,
Active.
NOTE
For UL Listed products, burglar alarm inputs must be supervised.
