The indicator window of the module is green (normal). When the module deteriorates, the indicator window turns red and must be replaced in time.between/div>betweendiv>2. The surge protector can be equipped with (FS) remote remote signal alarm. The remote signal contact has one normally open and one normally closed. If one or more modules of the surge protector fail, the contact will be closed and a fault alarm signal will be sent. Indicates that the module is faulty and must be replaced.between/div>betweendiv>3. Frequently check the air switch or fuse on the serial line.between/div> Package List 1 x Surge Protective Devices
