3.1 DIP Switch Settings
The following tables list the programmable features for the MS-2 and MS-4. 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.
