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 DataLock system uses lockcodes to lock panels from programming by unauthorized programmers. A Datalocked panel has a lockcode in memory that the 5200 must match to one of the lockcodes in the 5200 lockcode records before the programming session can continue. If 5200 cannot match the lockcode in the panel, the programming session is terminated.
The D192G panel zone (point) is in trouble and the yellow LED is not on.
With the zone/point in trouble and No Yellow LED On there is a wiring fault. One of the following terminals do not have power connected to them. External Power In (EXT PWR IN) and / or Auxiliary Power In (AUX PWR IN).
Terminal 1 (AUX PWR IN) 13.75 VDC
Terminal 2 (Common)
Terminal 3 (Supervised Zone / Point) 2.50 VDC Normal Condition < 1.50 VDC In Trouble condition
Terminal 4 (Trigger) 13.75 VDC In Alarm Only
Terminal 5 (External Power In) 12 VDC or 24 VDC Depended on needed Output for the NAC's or Power Supply
Terminal 6 (Common) This is the Common from an 24 VDC External Power
Terminal 7 (Positive Alarm Output)
Terminal 8 (Negative Alarm Output)
