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.
