Hardwired 4009 IDNet Control 
There are two hardwired NAC control inputs to the 4009 IDNet (when used as 
an IDNet device on a 4010 these inputs are not used).  The hardwired NAC 
control inputs provide backward compatibility with other Simplex panels.  In the 
hardwired mode, the 4009 IDNet is non-addressable and controlled via two DIP 
switches (Hardware Configuration Switch SW1 and Software 
Address/Configuration Switch SW2).  Each input simulates a typical hardwired 
notification appliance, as seen from the host panel.  When a fault occurs on the 
4009 Addressable NAC system or on any of the outputs controlled by Input 1, 
the panel causes an open condition on the host NAC that is connected to Input 1.  
Any faults on the outputs controlled by Input 2 are reflected on the host panel’s 
NAC in the same fashion.  A power loss condition at the 4009 IDNet causes 
Input 1 to indicate a fault (open) condition. 
Inputs 1 and 2 can be configured either as EOL devices on the host NAC or as 
applian
ces on that NAC, based on whether an end-of-line load is presented to the 
host.  Up to four 4009 IDNet NAC Extenders can be attached to the FACP(s) 
NAC. 
Addressable 4009 IDNet (IDNet Control) 
The 4009 IDNet is addressable when configured as an IDNet peripheral; this 
m
ode is also configured via DIP switches SW1 and SW2.  In the IDNet mode, 
SW2 (see Figure 5) sets the address of the NACs connected to the 4009 IDNet 
which are controlled and configured by the 4010 FACP.  The 4009 IDNet 
monitors each output NAC.  If a trouble occurs, faults (including NAC 
supervision, power, battery integrity, and earth) are communicated to the host 
panel 4010 FACP as IDNet messages.
