The FACP can be programmed to shut down a building's HVAC fans in the event of a fire. The fans cannot be restarted until the fire alarm

condition has been cleared and the FACP has been reset to a normal (non-alarm) condition.

IMPORTANT! This HVAC feature is not to be used for smoke control. It is only designed to shut down fans during a fire alarm condition.

E.1 Control Module Operation

E.1.1 HVAC SHUTDOWN

The HVAC SHUTDOWN type code can be assigned to any addressable control module for the purpose of shutting down HVAC fans during

a fire alarm, duct supervisory, photo supervisory, CO alarm, or CO supervisory condition. Devices connected to a relay module with this type

code are unsupervised. Devices connected to a NAC module with this type code are supervised. To program this feature in the FACP:

•

Program the HVAC SHUTDN RLY or HVAC SHUTDN NAC type code to the control module which will be used to shut down the

fans (refer to Type under the section titled "Edit Module Screen for Control Modules" on page 61).

•

Program the control module to a software zone and program fire alarm, duct supervisory, photo supervisory, CO alarm, or CO

supervisory input devices which, when activated are to cause fan shutdown, to the same software zone (refer to Zone Assignment under

the section titled "Edit Module Screen for Control Modules" on page 61).

•

If using a relay control module (CRF-300) for HVAC shutdown, monitor the state of the control module using an addressable monitor

module programmed for Trouble Monitor. (Refer to Type Monitor under section titled "Edit Module Screen for Monitor Module" on

page 57.) The monitor module's display label must be programmed to display HVAC SHUTDOWN. When a shutdown event occurs,

the control module will both shut down the fans and activate the monitor module. When the control module is active, the monitor

module will indicate a trouble condition at the FACP along with the label HVAC SHUTDOWN.

•

If using a NAC control module (CMF-300) for HVAC shutdown, monitor the state of the control module using an addressable monitor

module programmed for Trouble Monitor and a MR Series relay (MR-101CR). (Refer to Type Monitor under section titled "Edit

Module Screen for Monitor Module" on page 57.) The monitor module's display label must be programmed to display HVAC

SHUTDOWN. When a shutdown event occurs, the control module will activate the MR Series relay which in turn will both shut down

the fans and activate the monitor module. When the control module and MR series relay are active, the monitor module will indicate a

trouble condition at the FACP along with the label HVAC SHUTDOWN. Note that the 24 VDC power used by the control module must

be supervised using another addressable monitor module and a EOLR-1 power supervision relay.

FACP

Once activated, the HVAC SHUTDOWN control module remains activated, even if the FACP is silenced or reset. After all the fire alarm,

duct supervisory, photo supervisory, CO alarm, and CO supervisory condition on the FACP have been cleared and the panel reset, the HVAC

SHUTDOWN control module remains activated and the fans remain off. The fans can only be restarted when the HVAC SHUTDOWN con-

trol module is deactivated by the HVAC RESTART module.
