D9124 Assembly
System Components
The D9124 Addressable 24 VDC System ships in three separate packages. The
D9112LTB Control/Communicator comes in one package; the D9101 enclosure comes in
another package; the D9100 accessory module carrier, a D1601 transformer, the
transformer enclosure and literature ship in a third package.
You should have the following components when you receive your D9124 Addressable
24 VDC System:
• One D9112LTB Control/Communicator (without terminal blocks)
• One D9101 Enclosure assembly
• One D9100 Accessory Module Carrier, which includes the following:
• One D8125 POPEX Module
• Two D192C Indicating Circuit Supervision Modules
• One Literature Pack
• One D928 Dual Phone Line Switcher Module (with cables)
• One D1256 Fire Command Center
• One D9142 24 VDC Power Supply
• One D1601 hard-wired Dual (16.5/24 VAC) Secondary Transformer
• One motherboard
• One wiring harness
• One extra wiring harness for D8125 Popex Module
• Two 560 Ohm Resistors (for D192C modules)
• Two D161 Dual Modular Telephone Cords
• One D162 Dual Modular Telephone Cord
Minimum Battery Requirements
You also need two D126 12V, 7Ah batteries (or D1218 12V, 17.2Ah batteries) for standby
power for the D9112LTB, the command centers and modules. Two additional batteries
(D126 12V, 7Ah) are needed to provide standby 24 volt power for the 24V devices
connected to the D9124 System. If more than 7Ah capacity is needed, use a UL listed
enclosure for additional batteries. Mount the battery enclosure adjacent to the D9124.
Use conduit to connect the two enclosures. These batteries are not provided, but are
available from Radionics (also contact Radionics for other enclosures and power
supplies). See Auxiliary Current and Standby Battery Requirements for information about
meeting minimum battery requirements.
Caution: all battery lead connects are not power limited!
Use only sealed lead acid batteries: The power supplies in the D9124 System are
designed to operate with sealed lead acid batteries. Using any other type of battery can
cause damage to the D9124 System’s power supplies.

Module (1), D192C Indicating Circuit Supervision Modules (2), D928 Dual Phone Line
Switcher (1), Motherboard (1), D9142 24 VDC Power Supply (1).
