The HVAC OVRRIDE type code can be assigned to any addressable monitor module for the 
purpose of overriding or preventing the HVAC SHUTDN control modules from activating and 
shutting down fan during an alarm or manual evacuate condition.  The HVAC OVRRIDE monitor 
module acts globally throughout the FACP system and therefore is not programmed to a particular 
software zone.  To program this feature in the FACP:

• Program the HVAC OVRRIDE type code to the monitor module which will be used to 

override the HVAC SHUTDN control module and prevent the fans from turning off (refer to 
Type Monitor under the section titled  "Edit Module Screen for Monitor Module" on page 
59).

The HVAC OVRRIDE monitor module does not latch when activated.  Activating a switch 
connected to the monitor module will override all HVAC SHUTDN control modules in the system, 
preventing the fans from being turned off and causing the FACP LCD to display an active HVAC 
OVRRIDE module.  Releasing the switch will allow the HVAC SHUTDN control modules to 
activate, turning off the fans.

Note: Activation of the HVAC OVRRIDE module causes a trouble event that will be 
communicated to the Central Station if enabled.
