14     Horn Output    The custom alarm module (CAM) is an attachment that can be mounted at the generator set or at a remote location. The CAM annunciates faults, alarms or other conditions. Customer supplied inputs give the CAM this information. The CAM operates when it is powered only by 24 DCV or 32 DCV battery systems. The CAM is equipped with a horn, alarm silence switch, a lamp test switch, and 8 switched inputs for customer use. Note: A basic version of the CAM also exists. The basic version does not have a horn, an alarm/silence switch or a lamp test switch. The basic CAM is to be used with a existing fully equipped CAM or ALM.Alarm Operation A given switch input corresponds to 1 of 8 indicators on the face of the CAM. The indicators will FLASH at a rate of 2 hertz when the corresponding input is closed to battery negative. The red indicators are used to display shutdown conditions, and the amber indicators are used to display alarm conditions. When an input corresponding to one of the red indicators is activated, the indicator will flash and the horn will sound. The input is connected to battery negative when the input is active. When the input is disconnected from battery negative, the horn will continue to sound and the red indicator will continue to flash. This annunciation continues until the alarm silence switch is pressed. When an input corresponding to one of the amber indicators is activated, the indicator will flash. The horn does NOT sound. When the input is disconnected from battery negative, the amber indicator will turn off. Alarm Silence Function The alarm silence switch is activated by connecting the corresponding input to battery negative. When an input is connected to battery negative, activating the alarm silence switch causes the horn to cease. The indicator stops flashing and the indicator changes to being ON continuously. The alarm silence function will be overridden if the following event occurs. The status of any of the eight switched inputs changes and this change causes additional inputs to be closed to battery negative. The alarm silence function will not be overridden if the change in status is
