Power Outputs
Circuit Protection
Three self-resetting thermal circuit breakers protect the panel from short circuits on both
the continuous and programmable power outputs. The circuit breakers are thermal rated
and open at 3 to 5 Amps. If the panel is programmed for power supervision and short is
sustained on one of the power outputs, the panel transmits a BATTERY LOW or
BATTERY MISSING for Modem II, or TROUBLE ZN 9 for BFSK.
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.
