AC Power
The Protege Controller shall be supplied by a dedicated electrical power source rated for a minimum 10Amp
load and have a dedicated circuit breaker. Do not use a switch controlled breaker or a switched electrical point
to supply electrical power. Connect the primary (120VAC) of a 16 to 16.5 VAC, 60Hz, 40VA or 100VA
transformer (refer to the table below) to the electrical circuit and run the secondary (16 to 16.5VAC) to the AC
Input on the Controller terminals.
UL
ULC
The following table outlines the transformers that shall be used in order to comply with UL and ULC
installation standards.
When installed with the power supply manufactured by Marcus, Model M4758CT:
the Digital Security Controls (DSC) Model ULC-LA power indicator light assembly (Installation
Instruction No. 29001877 R0) must be installed within a conduit knockout of either the ICT Model
CAB-LARGE-UL or Bosch Model D8108A enclosure in order to provide green AC power on
indication.
the Littelfuse Part No. 150322 fuseholder and Littelfuse Part No. 0312005 5A, 3AG fast-acting
fuse must be installed in-line to the Models PRT-CTRL-SE, PRT-ZX16-PCB, and PRT-RDI2-PCB.
For ULC Central Station Fire Monitoring installations, a hardwired connection type transformer is
required. Check with the local authority.

AC Power Connection
Specific regional regulations may allow the transformer to be mounted inside the cabinet enclosure. In this case
wire the electrical circuit to the electrical termination point inside the cabinet enclosure and the secondary wires
of the transformer to the AC Input on the Controller. The earth wire shall be routed to the V- terminal on the
Controller when using an internal transformer.
Warning:
This installation should be made by qualified service personnel and should conform to all local
codes and in accordance with the National Electrical Codes (NEC US) or the Canadian Electrical
Codes (CEC Canada).
Termination of wiring to the Controller while power is applied or the battery is connected may
cause serious damage to the Controller and will VOID ALL WARRANTIES OR GUARANTEES.
Power the unit only after all wiring, configuration and jumper settings are completed.
Extra care must be taken when wiring the AC inputs. Improper connection will cause permanent
damage to the Controller.
