Features and Specifications 

 

Main Electronics (inside master detector assembly) 
Specifications 

 

Liquid  Crystal  Display:

  4-line  by  20-character  Liquid  Crystal  Display 

(LCD)  for  display  of  detector  background,  count  rate  for  each  channel 
(detector), and sigma level above background while sensors are occupied.   

Mains Power

: able to operate from 100-240 Vac, 50/60Hz, maximum 250 

watts, without a voltage selector switch. The system also has a 12-volt, 12 

amp/hr  trickle-charged  battery  backup,  providing  up  to  20  hours  of 
continued operation in non-alarming condition. 

Fuse

:  250 Vac 1-amp main AC fuse AGC-1; 10-amp battery fuse ABC 10. 

Detector Cable

: Belden 9768 or equivalent, 12 twisted pair conductors with 

individual shields, 22-gauge wires. 

Preamp Cables

: Belden 8305 or equivalent, 5 pair, 22-gauge wires.

 

Output

:  RS-232, Ethernet, and dry contacts for radiation alarm and status 

conditions.

 

Remote Cable

:  Belden 9946 or equivalent 15 conductors, overall shielded, 

22-gauge wires.

 

Sensitivity

: dependent on number and type of detectors.

 

Microprocessor Sampling

: The microprocessor uses a sliding-bin method 

to scan sample data while the portal is occupied. In this mode, checking is 
performed every 100 milliseconds while the portal is occupied. 

Enclosure

: The Model 4525 electronics are housed in the master detector’s 

weather-tight (NEMA-4 dust-tight and water-tight) enclosure.
