  Description 
  This option controls the conditions that will activate relay or sounder detector bases. 
Select from the following values. 
Head: The base is controlled by the detector’s settings. 
•  The base activates when the detector goes into alarm, unless the detector is set 
for alarm verification. 
•  If the detector is set for alarm verification, the base activates when the detector 
goes into alarm verification. It does not restore, however, until the alarm restores. 
•  The base does not respond when the detector goes into prealarm no matter how 
the detector is configured. Also, the base only follows the primary element of a 
dual element detector. Any activation from a secondary element does not trigger 
the base.  
  Example: When using a PCOS/PCD (Smoke/CO) detector and assigning it the 
Follow "Head" option, the activation of the photoelectric element will cause the 
local sounder/relay base to activate automatically.  However, if the CO element 
portion of the device activates without the activation of the photoelectric element, 
the sounder/relay base will not activate. 
•  Devices with the base set to follow Head cannot be placed in correlation groups. 
When a device base is set to follow Head, the base is removed as an output from 
any correlation groups to which it belongs. 
Alarm: The base activates its relay when the detector goes into alarm. The base will 
not restore until the alarm event has been restored. Any activation from a secondary 
element (Active3) does not trigger the base. For CO device operation, see Follow CO 
below. 
Alarm and verify (ALM+VFY): The base activates its relay when the detector goes into 
alarm verify and continues when the detector goes into alarm. The base will not 
restore until both events have been restored. 
Alarm and prealarm (ALM+PALM): The base activates its relay when the detector 
goes into prealarm and continues when the detector goes into an alarm. The base will 
not restore until both events have been restored. 
Riser: The base is triggered individually by the loop controller (sounder bases only). 
None: A correlation group triggers the base. It can be applied to both relay and 
sounder bases and is used for relay bases configured as latched output devices. 
Note: All base follow settings except Head and Riser can be activated by correlation 
groups. 
  This option controls the conditions that will activate relay or sounder detector bases. 
Select Yes to allow the device’s secondary element (example CO) to activate the base 
programmed functions. 
Note: This option is not available for Base Follow types of Head, Riser, or None.
