apC/L Basics

I/8 Input Module The I/8 (input module) or board has eight
supervised inputs. Supervised inputs report on the status of the wiring
between the apC/L and an alarm device. If that 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 apC/L:
n
Short
n
Open Loop
n
Line Fault
n
Normal
n
Alert
Since a short circuit, open loop, or line fault can mask an alarm condition,
supervised inputs enhance system security.
As a separate module connected to the apC/L reader bus, the I/8 provides
eight Class-A supervised inputs. A total of four I/8s (input modules) can
be connected to the apC/L, providing up to 32 Class-A supervised inputs.
A 1 K ohm resistor is factory-installed on all inputs. These resistors must
be clipped out when you use the associated input. Tolerance on states is
± 5%. The I/8 (input module) will not function until the apC/L is
configured by the host computer.
R/8 Output Module The R/8 (output module) connects to the apC/L
reader bus, and provides eight auxiliary relay outputs. Each output is rated
at 30V DC/AC at 1Amp inductive, 2Amps non-inductive. You can
connect up to four R/8s (output modules) to the apC/L, providing up to 32
auxiliary relay outputs. Note that the R/8 (output module) cannot function
until the host configures the apC/L.
Note An unsupervised input does not monitor the wiring.
Unsupervised inputs can report two conditions: Normal or Alert.
The I/8 (input module) has no unsupervised inputs.
