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
Radionics’ Modem IIIa
2
™ Communication
Format, 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
+.
Total Available Power
The system produces up to 1.4A of combined
power at 10.2 VDC to 13.9 VDC for all powered
devices. The outputs listed below share the
available power. These outputs are shown as red
circles on the face plate.
Terminal 3 - Auxiliary Power. Use this terminal
to power devices requiring continuous power. To
increase output by 1.4 amps, connect a D8132
module to this terminal.
Terminal 6 (Relay A) - Alarm Power Output.
Normally open, power on alarm.
Terminal 7 (Relay B) - Alternate Alarm Power
Output. Normally open, power on alarm.
Terminal 8 (Relay C) - Switched Auxiliary
Power. Normally open, power off on reset.
Terminal 24 - ZONEX Power. Use this terminal to
power ZONEX modules such as the D8125,
D8128C, and D8129 modules. To increase
output by 1.4 amps, connect a D8132 module to
this terminal.
Terminal 32 - Power +
Use this terminal to power SDI (Serial Device
Interface) devices such as command centers, the
D9131A Parallel Printer Interface, and the
D9210B Access Control Interface. To increase
output by 1.4 amps, connect a D8132 module to
this terminal.
Accessory Connector (J2)
The D928 Dual Phone Line Switcher connects to
J2.
Expansion Port (J4)
The Expansion Port is reserved for future use.

Continuous Current Draw
The continuous current draw for powered
devices connected to terminals 3, 8, 24, and 32,
the Expansion Port (J4), and the Accessory
Connector (J2) must not exceed 1.4A . Devices
powered from these outputs must operate over a
range of 10.2 VDC to 13.9 VDC.
Power restricted for fire and combined fire/
burglary systems: Use the Fire System Power
Formula to calculate the current available for fire
and combined fire/burglary systems. See
Programmable Power Outputs.
Increasing Current Output
D8132 Battery Charger Module
The D8132 Battery Charger Module increases
total output from 1.4 amps to 2.8 amps. Up to four
D8132 modules can be connected to the panel.
Figure 5 shows the terminal connections for the
D8132 modules.
Warning: Do not connect a D8132 module to the
battery terminals 4 and 5. Ensure AC power for
the panel and all connected D8132 modules is
on the same circuit.

Programming
The power outputs at terminals 6, 7, and 8 are
programmed as relays A, B, and C. All relays are
programmed in the
Relays module of the
program. Relays are assigned a relay type, Fire
Bell for example, when they are assigned to an
area. Relays can be assigned to one or more
areas.
