Issue What is the Battery Charging Voltage on a D8112 Control Communicator? Solution The float voltage for the Battery Charging Circuit on a D8112 is 13.9 VDC at a maximum current of 1.4 Amps. The actual current available can be found by deducting any continuous load from 1.4 Amps. Part numbers D8112, D8112E, D8112E1, D8112G, D8112G1, D8112G2

Panels DS7400XI, DS7400XIVER3+, DS7400XIVER4+, 

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. Part numbers D192C, D192G, D7212, D7412,D9112, D9124, D9412, D7212G, D7412G, D9112G, D9124G, D9412G
