PSN-106:3
PSN-106, PSN-64, PSB-10 • 5403590 • REV A • 12/09
General Description
The Potter PSN series of power supplies is designed to provide the power and fl exibility needed for the most demanding fi re
system installations. The PSN-106 is a 10 Amp 24Vdc switch mode power supply design which is up to 50% more effi cient than
linear mode supplies the PSN series is your best choice for powering fi re system notifi cation appliances and accessories. New
and retrofi t construction requirements for ADA compliance are easily accomplished with ample power for additional notifi cation
appliances along with the ability to synchronize the notifi cation appliances using built in sync generation for Potter, System
Sensor ®, Gentex® and Wheelock ® notifi cation appliances. The PSN series goes even further to make retrofi ts easier with the
advanced QuadraSync feature which allows notifi cation appliances from different manufacturers to sync with each other. You
also have the option to monitor an existing circuit by placing a reference resistor of the same value on the power supply and
continuing to monitor the circuit without changing the fi eld EOL.

fasteners. Five mounting holes are provided to accept ¼ inch diameter screws maximum. There are seven knock outs provided.
Operating Instructions
Alarm Condition
Notifi cation Appliance Circuit:
Alarm devices operate in unison with the Trigger inputs from the main Fire Alarm Control Panel (FACP). When activated by
the corresponding trigger input the associated Notifi cation Appliance Circuit (NAC) will reverse polarity from a supervision state
to the alarm state and supply power to the associated notifi cation appliances until the trigger is removed. Each activated NAC
will also power the L.E.D. associated with it, the L.E.D. will follow the steady or pulsing state of the NAC. The alarm-activated
outputs are reset through the operation of the reset function of the Main FACP.
