Zone Light The zone lights are “off” when everything is normal. A zone light will be “on” if the zone has been 
bypassed. If a zone light is “flashing”, that zone is in alarm or has been faulted. If a zone light is 
“flashing” rapidly, it means that the zone is in a trouble condition.   Trouble conditions are 
 
 Tamper      Hardware      Low Battery      Loss of supervision 
  
(A combination of Alarm/Fault and Tamper/Trouble will produce a rapid “flashing” light for a short 
period of time, followed by a slow “flashing” light.) 
 
 
 
 
 
 
 
 
 
EMERGENCY ACTIVATION KEYS 
 
 
 
NOTES: You must hold these keys for 2 seconds to activate these functions. Your system may not be programmed 
for these activation keys. You should press these keys only in an emergency situation that requires response by 
emergency personnel.   If your system is programmed for these functions, the following reports can be sent. 
 
Fire Key – This key can activate the fire alarm when pressed for two seconds. If your system is connected to a 
monitoring center, an emergency report could be sent to that center. 
 
Auxiliary Emergency Key – This key can activate the auxiliary alarm when pressed for two seconds. If your system 
is connected to a monitoring center, an emergency report could be sent to that center.  
 
Police (Panic/Hold-Up) Key - This key can sound a local audible alarm when pressed for two seconds. If your 
system is connected to a monitoring center, an emergency report could be transmitted to that center.  NOTE: Some 
Panic/Hold-Up alarms are programmed to be silent at the protected site while reporting an alarm to the monitoring 
center. Check with your installing company to determine how your security system will respond to the Panic/Hold-
Up activation.
