When a fire alarm occurs, the control panel activates Relay A (Terminal 6), providing the trigger input to the “Horn” D192C/D192G. The output from Relay A also changes Point 3’s voltage to 5.0 VDC (electrically, an open condition caused by the 2.4 k. resistor), causing an alarm (burg alarm) condition. This activates Relay B (based on the Summary Alarm Relay programming shown above). Relay B provides the trigger voltage for the “Strobe” D192C/D192G. When the Fire Alarm is acknowledged at the command center, power is no longer applied to Relay A causing the horns to silence and returning Point 3 to a normal state of 2.5 VDC. However, Relay B continues to stay activated until alarm memory is cleared at the command center by using Command 4 or entering Passcode + [ESC]. After the Fire Alarm is acknowledged, the command center first scrolls the fire alarm points, then scrolls AREA 1 1 ALARMS. This occurs because Point 3 is a Burg Point. Once a Command 4 or a Passcode + [ESC] is entered, the Alarm Memory is cleared.

The Timer Test is not coming in. The panel history shows Off Normal Test. The panel is programmed to send all reports in CID. Central does not see an E608 CID report for an off normal test.
Contact ID Reporting. The system can be programmed to send a periodic test report, E602, in Contact ID format. If any system troubles are present at the periodic test time, a new event, E608, which states “New event, off normal at time of periodic test report” is sent. Software versions 2.03 and before sent a generic system trouble P300 report.
