Form No. 06-795, Rev. 0 (02/16)
The key-switch (non-latching) and mini monitor module shall be utilized to activate the purge system for Zone 1, upon
completion of the “Purge Soak” period. For this example, the module shall be assigned to Loop 1, Address 34. The
monitor module shall be programmed as follows (See Figure 5).
1. In the Zone Assignments field assign the module to Zone 1.
2. In the Input Function field assign the input to “Process”.
3. Change the relay operation to “Non Latching”.
Figure 5 - Monitor Module Configured for “Purge” Activation
Note:
Activation of the key-switch by itself cannot initiate the purge function. In order to activate the purge function,
the “Purge Soak” timer must expire which allows the purge key-switch to start the purge function. Activation of the
purge key-switch prior to expiration of the “Purge Soak” timer will only initiate a process input to the panel.
The second addressable relay module shall be utilized to activate the mechanical components associated with Zone 1
purge operation (i.e., fans, dampers, etc.). Activation of this relay shall be triggered by the expiration of the “Purge
Soak” relay timer and the activation of the “Purge” key-switch. For this example, the module shall be assigned to Loop
1, Address 14. The relay module shall be programmed as follows (See Figures 6 and 7).
1. With
the
Common
configuration tab for the relay module selected, assign the device trouble assignment to
Zone 1.
2. In the Miscellaneous Option section, select “Independent Dry Contact” option.
3. Set the State option for the independent dry contact to “Process”.
4. Remaining configuration options, other than the custom message, should be left at default settings.
