Power Outputs
Circuit Protection
Three
One thermal circuit breaker protects Terminal 3 - Auxiliary Power and Terminal 24 - ZONEX Power and the Expansion Port (J4). A short on one disrupts the power to the others.
One breaker protects Terminal 6 - Alarm Power Output, Terminal 7 - Alternate Alarm Power Output, and Terminal 8 - Switched Auxiliary Power. A short on one of these terminals disrupts the power to the other two.
One circuit breaker protects terminal 32 - Power +.
Warning, Minimum Requirement for Wire Length: Connect powered devices to terminals 3, 6, 7, 8, 24, and 32 with at least 5 feet of 22 AWG wire or 14 feet of 18 AWG wire. A D9112, with devices connected with shorter lengths of wire, may not operate properly if AC power is interrupted.
Available Power
The D9112 produces up to 1.4A of power at 10.2 VDC to 13.9 VDC for powered devices. The outputs listed below share the available power.
Terminal 3 - Auxiliary Power
Use this terminal to power devices requiring continuous power.
Terminal 6 (Relay A) - Alarm Power Output
Terminal 7 (Relay B) - Alternate Alarm Power Output
Use terminals 6 and 7 to power devices requiring power on alarm. See Programmable Power Outputs.
Terminal 8 (Relay C) - Switched Auxiliary Power
Use this terminal to power devices requiring a programmable power interruption. Command 47 or Alarm Verification interrupts the power . See Programmable Power Outputs in this manual.
Terminal 24 - ZONEX Power
Use this terminal to power ZONEX modules such as the D8125, D8128A, and D8129 modules.
Terminal 32 - Power +
Use this terminal to power SDI (Serial Device Interface) devices such as the D1255 Command Center and the D9131 Parallel Printer Interface.
