1.2  4100U Basic Operations 
 
The  Fire  Panel  display  consists  of  two  sections  –  the  Operator 
Interface (upper section) and the Zone Isolate pushbutton switches & 
indicators  (lower  section).  Fire  detectors  are  grouped  into  zones 
(searchable  grouped  areas).  Zones  can be Isolated  by  pressing the 
zone‟s  isolate  pushbutton  on  the  panel  –  this  prevents  an  alarm  in 
that  group  from  activating  the  panel  outputs.  When  a  non-isolated 
detector  detects an  alarm, the fire  panel rings  the  bell, calls  the fire 
brigade, and activates the Warning or Evacuation System along with 
any other programmed functions (site specific).   
 
The  Operator  Interface  indicates  common  Alarm,  Fault  &  Isolation 
Status  on  LEDs,  and  point  (detector)  status  on  the  LCD.  When  an 
Alarm,  Fault  or  Isolation  occurs,  the  buzzer  will  operate  until  the 
corresponding „Acknowledge‟ (e.g. Fire Alarm Ack) key is pressed.  
 
The  panel  is  reset  by  pressing  „System  Reset.‟  If  the  alarm  won‟t 
reset  the  point  may  still  be  activated  (i.e.  detector  is  still  in  alarm). 
Press „Fire Alarm Ack‟ when the point alarm is displayed, then press 
„Disable,‟ „Enter.‟ Press „Fault Ack‟ (to acknowledge the fault caused 
by  disabling  a  point),  then  press  SYSTEM  RESET  again.  The 
disabled detector must be re-enabled when the condition is cleared.
