Overloaded Power Supply

If the load on the D9112's power supply exceeds it's capacity, the panel follows a routine to protect itself and the battery. It sends reports to the receiver at several points during this routine.

Keep in mind that AC power remains at terminals 1 and 2 as you read the overload scenario below.

The panel is operating normally with a good battery, AC is present at terminals 1 and 2, and auxiliary power load is under 1.4A.

Combined load on terminals 3, 6, 7, 8, 24, and 32, and connector J2 and J4 exceeds and remains above 1.4A. Device failure or premises wiring ground faults might cause the increased load.

The panel begins drawing on the battery to support the increased load. The yellow charging status LED turns on.

The battery begins to drain. When voltage drops to 12.1 volts, the panels sends a LOW BATTERY report and turns on the red Low Battery LED.

When the battery drops to 10.2 volts the panel disconnects it to protect it from deep discharge.

If AC is still present, the panel removes power to terminals 3, 6, 7, 8, 24, and 32, and connector J4 to protect its power supply. The green operation monitor LED turns off, but the panel is still operating.

The panel sends BATTERY MISSING, PT BUS TROUBLE, and SDI FAILURE reports.

If a D128 module is connected to J2, it begins sounding.

After approximately 60 seconds the panel attempts to return to normal operation by returning power to terminals 3, 6, 7, 8, 24, and 32, and connector J4.

If the overload condition is still present, the panel removes power.

The panel attempts to return to normal operation approximately every 60 seconds.

The cause of the overload is removed. Combined load on terminals 3, 6, 7, 8, 24, and 32, and connectors J2 and J4 remains below 1.4A.

With the overload removed, the panel returns power to terminals 3, 6, 7, 8, 24, and 32, and connector J4. The panel sends PT BUS RESTORAL and SDI RESTORAL reports.

If a D128 module is connected to J2, it stops sounding.

If the battery voltage is below 8.4 volts, the panel does not reconnect it. You must replace the battery.

When the battery reaches 13.7 volts the panel sends a BATTERY RESTORE report and turns off the red Low Battery LED.

When the battery reaches 13.9 volts the panel turns off the yellow Charging Status LED.
