3.1 DIP Switch Settings
The following tables list the programmable features for the Flex 402 and Flex 404. Placing a DIP
switch in the ON position will select the feature while placing the DIP switch in the OFF position
will deselect the feature. The exceptions to this rule are SW3 DIP switches 5 & 6. These two
switches are used to select the Notification Appliance Circuit synchronization feature. A detailed
description of each feature is presented in the following pages.
Important: When any programmable feature is changed by repositioning a DIP switch, the FACP
Reset button must be pressed to ensure that the control panel can read the new switch position.
