MODELS P531, P532 AND P532UI OPERATING MANUAL 

If the viewing head is not listed.  

If the viewing head is not listed as a choice in either 

the Viewing head or the channel branch: 

Check that the viewing head is compatible with the 

P531/P532. 

Check that the viewing head cable is in good condi-

tion. 

Verify that 24 volts DC is present at the cable head.  

Note: power to VH #3 is pulsed when no viewing 

head has answered. Check that the viewing head is 

operational. 

A meter or Oscilloscope on the SC with reference to 

ground will show: 

At least 20% duty cycle at 15 volts Peak for 

S55x viewing heads. 

At least 10% duty cycle at 24 volts Peak for 

S70x/S80x viewing heads.   

With S70x and S80x viewing heads the Green LED 

will flash once per second. 

S55xx viewing heads will show a number on the 

display. 

Viewing heads without numeric displays will flash if 

flame signal is present. 

Substitute a known good viewing head using a 

known good cable. 

Channels display LKOUT 

Channels display LKOUT that will not stay cleared 
(after pressing any key). 

Viewing head problem or cable problem. See above 

steps. (Reset OPTION defaults). 

The Display flashes “HOT”  

Indicates that the viewing head listed is nearing or 

exceeded maximum operational temperature.  The 

system will try to continue operating as long as it can 

and the flashing display is only a warning. 

CODE display. 

This is an indication of a processor failure. 

 It can be caused by a power failure during a memory 

store operation or other more serious fault.  

If the unit is not restored by cycling the power and set-

ting factory defaults: 

Record the numbers on the display.  

Remove the unit from service and return it to 

the factory for failure analysis and repair.
