Tyco Safety Products / Software House PI26 User Manual

The apC/8X panel supports the following optional boards:

I/32 Supervised Input Module (1 module)
I/8 Input Bus Module (8 modules)
R/8 Output Bus Module (8 modules)
R/48 Relay Module (2 modules)
Standard star coupler (1 module)
Mini star coupler (1 module)
Wiegand/proximity star coupler (lower and upper modules)

Note: The Mini star coupler has not been evaluated by UL.

The 

I/32 

Supervised Input Module (part #132-521) is a separate board, 

mounted directly on the apC/8X motherboard. If one or two R/48 modules are 
also used, then the apC-I/32 mounts on the outermost apC-R/48. 

The I/32 adds 32 supervised Class A two-wire inputs to an apC/8X. 
A 1K-ohm resistor is factory-installed on all inputs. These resistors must be 
cut off when you use the associated input. Tolerance on states is ± 5%. The 
I/32 does not function until the host computer configures the apC/8X. 

The I/8 Input Module (part #AS0073-00) provides eight additional 
supervised alarm inputs. You can install up to eight Input Modules on an 
apC/8X anywhere along an RM Reader Bus to provide up to 64 additional 
inputs.

The R/8 Output Module (part #AS0074-000) connects to the apC/8X reader 
bus. The Output Module provides eight auxiliary relay outputs. You can 
connect a total of eight Output Modules to the apC/8X anywhere along an RM 
reader bus to provide up to 64 auxiliary relay outputs.
