3.7. Isolate Menu
This menu selection allows for devices to be isolated so they do not respond to an alarm. Zones and points may be
temporarily isolated (taken out of service) for many reasons------device repair, circuit repair, etc. Only Customer Manager
status levels and above may access these menu options.
Note: When system points are isolated, the SYSTEM TROUBLE LED and ZONE
TROUBLE LED related to the isolated point(s) are lighted continuously and the front
panel buzzer will sound intermittently.
