 Paragon-III Technical Manual

 

 
3.1.6.1 

The rear connections (convection-cooled model shown; fan-cooled model not illustrated) for each of 
the power supply are: 
Fail Alarm –  
Off: Power supply OK; approx. +Vout (via 1k resistor - typ. 13.8V).  
ON: Power supply failure; approx. -Vout (via 11k resistors - typ. 0V)  

+ Remote – Not used for Paragon  
- Sense     – Not used for Paragon 
-VE – main ground (0V) 
+13.8V – Mains DC output supply 
Note: more power supply installation details 
are covered in section 2.5.1 

Figure 12 - Dual power supply, rear connections 

A single PCB backplane is used. The main components are: 

• 

RJ11 connectors (J11, J12) – connects to the Speaker panel front RJ11. Used for program-
ming the Radio modules.  

• 

DB-25F port to ancillary equipement 

• 

One channel-select DIP switch (SW1)  

• 

Cooling fan driver – TB 3 located on backplane connects to the horizontally-mounted fan on 
top of the Radio assembly and activated by BDLC’s PTT signal (setting JP1 2-3 will power 
the fan continuously). 

• 

30 A Fuse  (F2 & F3) – two blade fuses (15ADC) in parallel are used for future Power ampli-
fier 

• 

10 A Fuse (F1) – one blade fuse to power the other base station components (receivers, ex-
citer and optionally the BDLC).
