Figure 7 - Relay Module Configured for “Purge” Operation 

Upon activation of the relay module, its contacts will transfer causing activation of the modules feedback input (See 
Figure 4). This will cause a process input for address 1-014 to be received by the Cheetah Xi panel to provide 
indication of the purge system being active.  

Note:

 Where the suppression zone has more than one purge component (i.e., fan or damper), additional relay 

modules can be added to the system to perform purge functions utilizing the same programming process.  

Purge System Status Indication 

In order to provide visual indication of the status of the purge system operation, 
Fike’s 20-Zone remote LED annunciator can be used (See Figure 8). For this 
example, the annunciator shall be programmed as follows (See Figures 9 and 10). 

1.  Configure LED 01 for “ON-Zone Release” for Zone 1. The yellow LED will 

turn on upon Zone 1 entering the release state. 

2.  Configure LED 03 for “ON-Device Activation” for Loop 1, Address 8. The red 

LED will turn on once the “Purge Soak” timer associated with relay module 
has expired. 

3.  Configure LED 05 for “ON-Device Activation” for Loop 1, Address 14. The 

red LED will turn on once the relay is activated for purge operation.
