Operating Instructions SECTION 4 The MS-2 and MS-4 have two modes of operation which are Normal and Walktest modes. Upon initial power-up, the system will be in Normal Mode. This section discusses operation of the control panel in the Normal Mode.
:DONWHVW 2SHUDWLQJ ,QVWUXFWLRQV 4.1.5 Walktest The Walktest button, which is located on the FACP membrane switch panel, allows a panel walktest to be performed. Pressing and holding the Walktest button for a minimum of two seconds causes the FACP to enter audible walktest. Pressing the Walktest button and then the Silence button and holding both for a minimum of two seconds will cause the panel to enter silent walktest.
2SHUDWLQJ ,QVWUXFWLRQV 6WDWXV /('V Silent Walktest To perform a silent Walktest, press the Walktest button, then press the Alarm Silence button and hold both for a minimum of two seconds. The Trouble, Walktest and Alarm Silence LEDs will blink at a ¼ second rate. A silent walktest will not activate the control panel Notification Appliance Circuits.
