Fire zone type.
FV (Fire Verify zone)
Used primarily for smoke detector circuits to verify the existence of an actual fire condition. When a Fire Verify zone
initiates an alarm, the panel performs a Fire Reset. If any Fire Verify zone initiates an alarm within 120 seconds after the
reset, an alarm is indicated. If an alarm is initiated after 120 seconds, the cycle repeats.
SV (Supervisory zone)
Used to provide 24-hour zone supervision to devices associated with fire systems. Typical applications are tamper
switches on Post Indicator Valves (PIVs), gate valves, and low and high temperature gauges.
CO (Carbon Monoxide)
This output turns on any time a Carbon Monoxide Zone (CO) is placed in alarm. The output is turned o using Sensor
Reset option while no additional CO type zones are in alarm.
