E.2 Monitor Module Operation
E.2.1 HVAC RESTART
The HVAC RESTART type code can be assigned to any addressable monitor module for the purpose of resetting (deactivating) the HVAC
SHUTDN control module and turning the fans back on. The HVAC RESTART 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 RESTART type code to the monitor module which will be used to deactivate the HVAC SHUTDN control module
and restart the fans (refer to Type Monitor under the section titled "Edit Module Screen for Monitor Module" on page 57).
The HVAC RESTART monitor module does not latch when activated. Pressing a switch connected to the monitor module will deactivate the
HVAC SHUTDN control module only if the event(s) that triggered the shutdown have been cleared. The HVAC SHUTDN control module
can be deactivated if trouble conditions exist on the FACP.
E.2.2 HVAC OVRRIDE
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. The HVAC OVRRIDE monitor module acts globally throughout the FACP system and there-
fore 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 57).
The HVAC OVRRIDE monitor module does not latch when activated. Activating a switch connected to the monitor module will override all
HVAC SHUTDN control relay modules in the system, preventing the HVAC SHUTDN modules from activating and causing the FACP LCD
to display an active HVAC OVRRIDE module and turn on the Supervisory LED. Releasing the switch will allow the HVAC SHUTDN con-
trol relay modules to activate with subsequent events, turning off the fans.
As an example, pressing the HVAC OVRRIDE switch with no fire alarms, duct supervisories, photo supervisories, CO alarms, or CO super-
visories in the system will prevent the fans from being turned off when an alarm does occur. As long as the switch is activated, the fans will
not shutdown for any alarms. If the system is still in alarm/supervisory condition when the switch is released, the fans will not shutdown
unless another alarm/supervisory event occurs after the switch is released.
Important! If an alarm/supervisory event exists in the system and HVAC Shutdown has already occurred, HVAC OVRRIDE will have no
effect on the HVAC SHUTDN control relay modules. HVAC OVRRIDE will prevent HVAC Shutdown from occurring only if it is initiated
prior to an alarm/supervisory condition.
NOTE: Activation of the HVAC OVRRIDE module causes a supervisory event that will be communicated to the Central Station if enabled.
