System Schematic For Alarm Module (ALM)The alarm module (ALM) is available as an option. The alarm module may be mounted on the front panel. Also, the alarm module may be placed at a distance from the control panel as a remote annunciator. The alarm module is used in order to satisfy the requirements of the customer. The alarm module may be used in order to satisfy National Fire Protection Association (NFPA) requirements by annunciating the presence of a diagnostic code.The ALM communicates with the GSC+ by a serial data link. When the data link malfunctions, all of the indicators on the ALM, that are controlled by the data link, flash at a rate of .5 Hz.Note: The maximum number of the ALM or the Customer Interface Module (CIM) that may be connected to the serial data link is equal to three. The maximum distance between a module and the GSC+ is 305 m (1000 ft). If these specifications are not met, the ALM indicators may begin to flash. Also, the GSC+ may show a CID 0333 FMI 04. If the setup is not in compliance with the specifications, reduce the number of modules and/or shorten the distance to the modules.Note: Diagnostic codes are created when the harness connector is disconnected from the GSC+ during these troubleshooting procedures. Clear these created diagnostic codes after the particular problem is corrected and the particular diagnostic code is cleared.The possible cause of a CID 0333 FMI 04 is a short to "B-"of the data signal.The GSC+ treats a CID 0333 FMI 04 as an alarm fault. Clear the diagnostic code from the fault log after troubleshooting is complete.Note: If a CID 0333 FMI 04 is active on the upper display and no alarm module is installed, then check the terminal strips on the subpanel for a short. Perform the check from the signal wire to "B-". Also, check the customer connection box for a short from the alarm data signal wire to "B-".Test Step 1. CHECK IF THE DIAGNOSTIC CODE IS ACTIVE
Turn the engine control switch (ECS) to the OFF/RESET position and then turn the ECS to the STOP position.
Press the "Alarm Codes" key.
Observe the upper display for a CID 0333 FMI 04. The diagnostic code is active if the upper display shows a CID 0333 FMI 04.
If the diagnostic code is not showing, enter the service mode and view the fault log. Check the upper display if the diagnostic code is active.Expected Result:A CID 0333 FMI 04 is active.Results:
OK - A CID 0333 FMI 04 is active. Proceed to test step 2.
NOT OK - A CID 0333 FMI 04 has not occurred. The diagnostic code is NOT active. Stop.Test Step 2. CHECK THE GSC+.
Disconnect the cable on the B- terminal of the battery or open
